== What is the Grid List? ==

There are hundreds (thousands?) of OpenSimulator-based virtual worlds out there. Many of them are free to use and welcome new users. This grid list is a community-generated list of such worlds. If you would like to experience an OpenSimulator-based virtual world before installing your own, try one of these.

'''IMPORTANT NOTE:''' The OpenSimulator project is not responsible for, nor in any way associated with, any grid listed on this page, nor for any grid's content or activities. Visit at your own risk. Also, there are no guarantees that these worlds are up and running.

== Public grids ==

'''Grid List Policy:''' Please list your grid only if uses OpenSimulator as a component. Do not include advertising language. The entries in the main list should just contain the grid name and the plain numbers as defined by the column headers. '''Please use [[Grid List/Template|this template]] for the subpages to keep the information in a comparable manner.''' Grids are listed in the order of appearance, so please add your entry to the bottom of the list. Anyone found inserting a grid up higher in the list will have their entry moved or removed.

You may want provide a link on your world's website back to the project by using the [[OpenSim Graphics|Powered by OpenSimulator logo]]. Credit is appreciated but not required.

If you own a grid and are interested in joining a grid association see this page: [[Grid Associations]]

Hypergrid Business maintains a list of active grids, updated monthly: [http://www.hypergridbusiness.com/statistics/active-grids/ Active OpenSim grids]

OpenSim Archives

=How do I use the OpenSim Archive Function?=

==Introduction==

The OpenSim Archive (OAR) function has existed since OpenSim 0.5.9. The facility does a similar job to load-xml2/save-xml2 in that it saves prims so that they can be later reloaded. However, OpenSim archives (OAR) go a step further in that they can save all the necessary asset data so that you may fully restore the terrain, region parcel data, the textures of objects and their inventories when loaded onto a completely different system using a different asset database.

== Usage ==

From the region console, one can type

save oar [--noassets] [-h|--home=<url>] [<filename>]

to save an OpenSim archive. If no filename is given, then the name region.oar is used in the current directory.

'''EXAMPLES:'''
save oar
save oar my.oar
save oar c:/mybackups/filename.oar
save oar oars/11nov.oar

To load an archive, type

load oar [--merge] [<location>]

at the console. The location can be a filesystem path (as for "save oar") or an HTTP address to load an oar directly over the web. If no location is given, then the server looks for a file called region.oar in the current directory.

'''EXAMPLES:'''
load oar
load oar my.oar
load oar --merge oars/3rd-party.oar
load oar http://path.to/oarfile.oar

By default, loading an archive will delete all the existing objects in the regions and replace them with the archive contents. It's like being in the Matrix (when they swap environments), except much slower (all the scene objects are slowly deleted before the new environment is loaded :-)

When an archive is loaded, owners will be restored if the relevant uuids can be found in the OpenSim installation's user database. Otherwise, prim ownership will default to the master avatar for the region.

I recommend that you use filenames with the extension '''.oar'''. The filename extension of the download links on this page is '''.tar.gz''' which illustrates that the '''.oar''' format is actually a zipped tar file.

=== Switches ===
==== Saving ====

===== --noassets =====

If the --noassets option is specified then the oar will be saved without assets. This can be handy if you're backing up the asset database separately and don't want the expense of including all the assets in each OAR.

===== --home =====

(formerly known as --profile up to 0.7.3)

If the --home option is specified then all names of creators from this world will be appended with links to their home world. It is not required that the service be operational; the information will be added and it will be available in all worlds that import this OAR.

<url> is the URL of this world's profile service.

Example:
save oar --home=http://mygrid.com my.oar

==== Loading ====

===== --merge =====

If the --merge option is specified then the oar will be merged with the existing region objects rather than replace them. The existing terrain, region settings and parcels will be left in place.

==Example OARs==

The [http://openvce.net OpenVCE.net] virtual worlds assets described at http://openvce.net/vwassets provided by Clever Zebra and the OpenVCE.net team at AIAI in the University of Edinburgh are available as an OAR (Opensim Archive) file.

http://openvce.net/resources/downloads/

Get file "opensim-openvce.oar" from there (right click on the file in the above directory in your browser, and select download is the easiest way to obtain the materials). A "full" set of the buildings with a large 400 seat amphitheatre intended to be placed on the corner of 4 sims is also available via "opensim-openvce-full.oar". Images of the buildings in place in Opensim are at:

==Further Information==

* [http://justincc.org/blog/category/oars/ http://justincc.org/blog/category/oars/] - various OAR related articles from justincc, including background information and possible future development.

==Use cases==

Possible current uses are

1. To migrate data from an SQLite region database to one based on MySQL

2. To distribute entire regions to other people.

==Current limitations==

* Performance is not very good, especially with large archives. This will be addressed in the future
* Loading large OARs using the default SQLite database plugin will take a very very long time (in the order of many hours). I highly recommend that you switch to MySQL if you want to load large archives.

==Upcoming enhancements==

===== --perm =====

A new option will be added when saving OARs:

save oar [--perm=<permissions>]

If the --perm option is specified then objects with insufficient permissions will not be saved to the OAR. The user whose permissions are checked is the estate owner. This can be useful for grids that allow their customers to export their regions to OARs, because it ensures that exporting to OAR can't be used to bypass content permissions.

<permissions> specifies which permissions are required. It's a string that contains one or more of these characters:
* "C" = Copy
* "T" = Transfer

Example:
save oar --perm=CT my.oar

==OAR Format==

The region [[OpenSim_Archives|OpenSim Archive (OAR)]] format is designed with three aims in mind:

# Make it easy for people to read and change individual objects, assets, etc. within an archive.
# Make it easy to compose two region archives into a single region archive.
# Make it easy to compose archives from scratch.

Therefore, all the different entities (assets, objects, terrains, etc.) are packaged in individual files (e.g. one for each asset) with human readable filenames and machine readable extensions (e.g. .jp2 for textures, .txt for notecards).

*[[OAR Format 0.1]]
*[[OAR Format 0.2]]
*[[OAR Format 0.6]]
*[[OAR Format 0.7]]

==FAQ==

1. What is this .tar.gz format you are using for the internal OAR format? Why not zip?

.tar.gz is a standard unix way of zipping up files into a single larger compressed file for distribution. Windows users should be able to open these files using freeware programs such as [http://www.7-zip.org/ 7-zip].

I'm using .tar.gz because all the zip (and tar) libraries for .net are licensed either under the GPL (with exception) or under the MSPL. Unfortunately, not all members of the OpenSim development team are comfortable with the MSPL, so these libaries are not currently an option. It is also significantly easier to write code to create and read tar archives than zip archives.

Also, if you're only ever loading and saving oars (rather than pulling them apart and putting them back together), then you don't need to worry about the internal format at all :)

2. Can you load and save multiple regions to an archive?

Not yet.

3. Can you load and save parts of a region to an archive?

Not yet.

==Bugs==

* Due to a possible bug in the Mono 1.2.4 libraries, this feature may cause a debug dump when used (the problem appears to be in writing out a compressed stream). Mono 1.2.6 is okay. Since Mono 1.2.4 is fairly old now, this bug will not be addressed.

==Current Status==

Operational. Bug reports are appreciated [[User:Justincc|Justincc]] 14:53, 14 September 2009 (UTC)

Though we will strive to maintain compatibilty for old archives with newer OpenSimulator versions, please don't rely on these archives as the only backup for regions.

OpenSim Archives

=How do I use the OpenSim Archive Function?=

==Introduction==

The OpenSim Archive (OAR) function has existed since OpenSim 0.5.9. The facility does a similar job to load-xml2/save-xml2 in that it saves prims so that they can be later reloaded. However, OpenSim archives (OAR) go a step further in that they can save all the necessary asset data so that you may fully restore the terrain, region parcel data, the textures of objects and their inventories when loaded onto a completely different system using a different asset database.

== Usage ==

From the region console, one can type

save oar [--noassets] [-h|--home=<url>] [<filename>]

to save an OpenSim archive. If no filename is given, then the name region.oar is used in the current directory.

'''EXAMPLES:'''
save oar
save oar my.oar
save oar c:/mybackups/filename.oar
save oar oars/11nov.oar

To load an archive, type

load oar [--merge] [<location>]

at the console. The location can be a filesystem path (as for "save oar") or an HTTP address to load an oar directly over the web. If no location is given, then the server looks for a file called region.oar in the current directory.

'''EXAMPLES:'''
load oar
load oar my.oar
load oar --merge oars/3rd-party.oar
load oar http://path.to/oarfile.oar

By default, loading an archive will delete all the existing objects in the regions and replace them with the archive contents. It's like being in the Matrix (when they swap environments), except much slower (all the scene objects are slowly deleted before the new environment is loaded :-)

When an archive is loaded, owners will be restored if the relevant uuids can be found in the OpenSim installation's user database. Otherwise, prim ownership will default to the master avatar for the region.

I recommend that you use filenames with the extension '''.oar'''. The filename extension of the download links on this page is '''.tar.gz''' which illustrates that the '''.oar''' format is actually a zipped tar file.

=== Switches ===
==== Saving ====

===== --noassets =====

If the --noassets option is specified then the oar will be saved without assets. This can be handy if you're backing up the asset database separately and don't want the expense of including all the assets in each OAR.

===== --home =====

(formerly known as --profile up to 0.7.3)

If the --home option is specified then all names of creators from this world will be appended with links to their home world. It is not required that the service be operational; the information will be added and it will be available in all worlds that import this OAR.

<url> is the URL of this world's profile service.

Example:
save oar --home=http://mygrid.com my.oar

==== Loading ====

===== --merge =====

If the --merge option is specified then the oar will be merged with the existing region objects rather than replace them. The existing terrain, region settings and parcels will be left in place.

==About OpenSim==
===What is OpenSim?===
OpenSim is a platform for operating a virtual world, and supports multiple independent regions connecting to a single centralized grid. This is somewhat similar to the web, where anyone can run their own web server, tied together through the internet. It can also be used to create a private grid, analogous to a private intranet.

===What is a region?===
A region is what you see when you log into OpenSim. It is the physical place (well, virtual physical space) where avatars move and interact. It is a square patch of land which may contain an island, mountains, a plain, buildings, etc., or just an ocean.

===What is the grid?===
The grid is the level that organizes the regions and their positions in the world, and handles things that need to exist across regions, such as a user's inventory. You can think of it as similar to the world map.

===What does ... mean?===
See [[Technical_Reference | OpenSim:Technical Reference]] for definitions of some terms commonly used in OpenSim.

==Configuring OpenSim==
First, read [[OpenSim Configuration]].
===Where can I get a new UUID for my sim config?===
* See [[OpenSim Configuration]]

===Can I run multiple regions with OpenSim?===
* See [[OpenSim Configuration]]

===What databases can be used with OpenSim?===
* See [[OpenSim Configuration]]

==Running OpenSim==

==Connecting to OpenSim==
===I've set up my OpenSim server and it looks like the login works but the client hangs on 'connecting to region'===

There are 2 steps to login.

1) When you start up the client and enter your name/password, it sends those details to the OpenSim login service. If your password is correct, it tells the region simulator that you're coming. It then sends back to you (the client) the ip address and port to use to enter that region (as gleaned from your Regions.ini file).

2) Your client then connects to the region using those details.

If the client hangs on 'connecting to region' then the details being sent to it in step 2) are not allowing it to connect. Check your Regions.ini carefully and try to telnet to the ip & port that should be available.

If you're seeing this problem after you've made your sim available to the outside world (where people outside your network can connect to it but you cannot) then you probably don't have a router that supports NAT loopback. This allows you to connect to a local machine through your router via an external address. See [[NAT_Loopback_Routers]] for a list of routers that support this feature.

==OpenSim in the Wild==
=== Are there test servers running OpenSim I can connect to? ===

Yes. Check out our [[Grid List]]! There are often many private servers up for testing. Hang out on the IRC channel (Freenode #opensim), and troll for URI's.

There are also several private organizations offering directories and search engines. They include:

*[http://www.hyperica.com Hyperica] -- a categorized directory of hypergrid-enabled OpenSim destinations, currently over 250 locations 
*[http://www.metaverseink.com MetaverseInk] -- ha key-word-based search engine for OpenSim grids, mostly those running the Diva Distro
*[http://www.gridhop.net GridHop] -- a list covering the major OpenSim grids, currently over 150 destinations accessible over hypergrid teleport
*[http://www.hgurl.com HGURL] -- a key-word-search database for all grid, all accessible via hypergrid (in progress API for acces to search engine and info in world).
*[http://www.thehypergates.com/ The HyperGates] -- The first dynamic, auto-updating HyperGrid directory for both HyperGrid 1.5 ( OpenSim 0.7.x ) and HyperGrid 1.0 ( OpenSim 0.6.x ) standalones & grids. Download the HyperGate from the site now and Join the HyperGate Network. The most reliable HyperGrid directory.

=== Are there any companies that will host my grid for me? ===

Yes there are dozens of independent OpenSim hosting providers. The following are not affiliated with OpenSimulator.org.

*[http://www.dreamlandmetaverse.com DreamLand Metaverse]
*[http://www.ReactionGrid.com/ ReactionGrid]
*[http://www.simhost.com SimHost]

More vendors listed here: [http://www.hypergridbusiness.com/opensim-hosting-providers/ Hypergrid Business Vendors Directory] -- a categorized directory of OpenSim vendors, currently listing about three dozen providers. 

=== Can I teleport from the Linden Lab Second Life grid to my Sim? ===
No. In 2008 and 2009, there had been the connection to vaak grid, [http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/ which enabled us to teleport from Second Life over to an OpenSim grid] before LindenLab closing it. As of 2010, "The vaak grid is currently unavailable as we transition from OGP based services to VWRAP based services."([http://wiki.secondlife.com/wiki/Open_Grid_Public_Beta "Open Grid Public Beta" in Second Life Wiki])

==MySQL==
===How do I isolate and delete a user's Trash items in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE!

CAUTION: The Linux default directory for the MySQL database is /var/lib/mysql Many backup tools (e.g. backupPC) do NOT back up /var/*! Make certain that the database and not just the MySQL code (/usr/bin/mysql) is included in your nightly backups! The actual paths will be different for different operating systems and databases, but the problem is the same.

'''1.''' Locate the avatars UUID you wish to find the trash items of, in the '''users''' table 
This query will locate a specified users UUID: (replace User/Test with username/lastname)
<nowiki>SELECT `UUID` FROM `users` WHERE `username` LIKE 'User' AND `lastname` LIKE 'Test' LIMIT 0 , 30;</nowiki>
 
'''2.''' Use the avatars UUID to search the field_name '''AgentID''' in the '''inventoryFolders''' table, using '''Trash''' as the '''folderName''' to isolate the users Trash '''folderID''' 
This query will locate the users Trash folder entry: (replace 00000000-0000-0000-0000-000000000000 with UUID of user)
<nowiki>SELECT `folderID` FROM `inventoryfolders` WHERE `agentID` LIKE '00000000-0000-0000-0000-000000000000' AND `folderName` LIKE 'Trash'
LIMIT 0 , 30;</nowiki>
 
'''3.''' Use the '''folderID''' UUID obtained in the last query to find all of the trash items in the '''inventoryitems''' table, you can then delete them once you have isolated them. 
This query will locate the trash items of the avatar in question: (replace 00000000-0000-0000-0000-000000000000 with Trash folder UUID obtained in the last query)
<nowiki>SELECT * FROM `inventoryitems` WHERE `parentFolderID` LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 9999;</nowiki>
 
'''NOTE:''' These steps will not remove the associated assets from the assets table, just the items in the inventory '''inventoryitems''' table.

===How do I isolate and resolve duplicate inventory folder entries in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE! 

'''1.''' It's first a good idea to search for the affected avatars UUID in the '''inventoryFolders''' table to see the duplicate entries. When you see this, you'll see the problem of duplicate entries. The key here will be to find out which is being used. 

'''2.''' Upload a file inworld and name it something unique. This will isolate the UUID of your root folder that is being used (even though there are dups only one is being used) 

'''3.''' Search the '''inventoryitems''' table for your uniquely named item and locate it's '''parentFolderID''' 
This query will isolate the '''parentFolderID''' based on your search for the unique item (replace '''unique_name''' with your unique item name)
<nowiki>SELECT `parentFolderID` FROM `inventoryitems` WHERE `inventoryName` LIKE 'unique_name' LIMIT 0 , 30;</nowiki>

'''4.''' Check the '''inventoryfolders''' table against the '''parentFolderID''' UUID obtained in the last search. That is your root folder that is being used.. you can delete all duplicate entries that do not match that parentFolderID. In the end, you should only have one of each type (Trash, etc) 
This query will return all values that are NOT the parentID obtained in the last search. (replace 00000000-0000-0000-0000-000000000000 with the parentID located in step 3)
<nowiki>SELECT * FROM `inventoryfolders` WHERE `folderID` NOT LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 30;</nowiki>

==In World Questions==
=== Does in world scripting work yet? ===
Not fully implemented, but there is a lot of work going on here. Please see [[ScriptEngines]], [[LSL Status]] and [[OSSL Status]] for the latest info.

===Can I customize my avatar?===
Yes. In order to do this:
* Click the Inventory Button
* Create -> New Clothes -> Shirt, Pants, etc
* Create -> New Body Parts -> Hair, Shape, etc
* Edit those from your inventory
* Wear them

Your avatar doesn't always face a nice direction for doing this, so you'll need to use the camera operations to see your face for some of the modifications. This is a known issue, will be fixed in the future. Also, you'll need to rewear you parts once you first join the environment. Right now default appearance is always "Ruth".

===Why do I look like I gas cloud right after I did the the previous steps?===
Second Life eliminated Ruth from their client. The Ruth we see in OpenSim is our own attempt of a yoga teacher and not truly Second Life's Ruth. When you create a shirt, pants, skin and shape and wear them without changing any parameters, the Second Life Viewer understands you are not Ruth. Since Ruth is no more, you become a cloud of gas. To fix it, either change a parameter of one of them before wearing all 4, or, if you already are a gas cloud, right click one of these items in your inventory and click edit. That should bring up the edit appearance menus. Just move any sliders and voilá.

===I used [[XEngine]], but my recent update caused [[DotNetEngine]] to come on again===
There were some changes and you will need to change or create the line DefaultScriptEngine = "XEngine" in the startup section to get XEngine back. See [[ScriptEngines]]

===Why doesn't my world map update when I edit the terrain?===
There are three approaches depending on just how adventurous you want to be. From the least to the most adventurous:
* Wait two days. You will need to restart your sim at the end of the two days to get the updates.
* Exit the .xml file for the region. Change the value in the "lastmap_refresh" attribute to "0". You will need to restart the sim.
* Not for the faint of heart! Edit the "WorldMapModule.cs" file and change the "LazySaveGeneratedMaptile" method to change the "RefreshSeconds" value to something less than two days. Be sure to read the comments and understand why things are the way they are.

Once your terrain stabilizes, this won't be much of a problem, but it is nice to see the updates while you're furiously developing something.

===Why are my knees bent when I stand idle?===
This seems to be a result of the ODE Physics Engine on 64 bit systems. A fix is to edit OpenSim.ini and change the following line:
* av_capsule_standup_tensor_linux = 550000
to
* av_capsule_standup_tensor_linux = 1700000

Note that this line of code is under the [ODEPhysicsSettings] section of the OpenSim.ini file.

===when I create a new skin and shape, the thing goes bonkers creating new assets constantly===
you have not configured an asset cache

you need to configure either the cenome cache or the flotsam cache

without an asset cache, temporary assets can't be held which means they are continously rerequested

copy either config-include/CenomeMemoryAssetCache.ini.example, or the relevant flotsam file, to .ini edit and set it up for your needs then check GridCommon.ini or StandaloneCommon.ini uncomment the line for that cache

(standalone defaults to cenome grid to flotsam)

==Grid Mode==
=== After the shiny new grid is running, what is next? ===
* Make sure one can stop/restart UGA &S (sims). Check out any ordering issues of stop/restart UGA w/o stop/restart sim(s).
* Make sure one can add/delete both a region and a user from the database.
* Make sure it runs overnight and check it each morning by logging into 1 or 2 key sims.
* '<tt>tail -f userserver.log</tt>' and watch/understand the login process.
* Make sure when you logoff your system, you can log back on and get control of the UGAS consoles.

==Region Statistics on a Web Page==
===Information about your regions.===
Region statistics such as region name, avatar name, avatar position<x,y,z>, number of prims, and a lot of other information can be obtained on a web page by:
* Adding the following to the bottom of the [[OpenSim.ini]] file
[WebStats]
enabled=true
* Using a web browser and typing in the "Login URI" + "/SStats/" of your standalone server.
For example- <nowiki>http://127.0.0.1:9000/SStats/</nowiki>
The resulting web page is continually updated using AJAX, so there is no need to refresh the page to obtain current information. One possible use for this web page information would be to see who is logged on to the region in real time - without actually logging in. 
This web page provides region information similar to the kind generated by using various server console commands to obtain region statistics. See [[Server_Commands]]

== Misc ==
=== You guys like April 1st, eh? Looks like the joke is on us... ===
Yes, every year we've had a piece of non destructive code in the unstable, unreleased, upstream subversion tree. The source tree that is only designed for testers and developers. In each case it has shown something that is possible in OpenSim that most people might not have realized. In 2008 this was an avatar created entirely from a Region Module (no user), in 2009 it was making all users a giant (and I mean giant) stick bug avatar. There will be more in the future, don't worry. The developers seem to have a sense of humor.

==Running OpenSim==

==Connecting to OpenSim==
===I've set up my OpenSim server and it looks like the login works but the client hangs on 'connecting to region'===

There are 2 steps to login.

1) When you start up the client and enter your name/password, it sends those details to the OpenSim login service. If your password is correct, it tells the region simulator that you're coming. It then sends back to you (the client) the ip address and port to use to enter that region (as gleaned from your Regions.ini file).

2) Your client then connects to the region using those details.

If the client hangs on 'connecting to region' then the details being sent to it in step 2) are not allowing it to connect. Check your Regions.ini carefully and try to telnet to the ip & port that should be available.

If you're seeing this problem after you've made your sim available to the outside world (where people outside your network can connect to it but you cannot) then you probably don't have a router that supports NAT loopback. This allows you to connect to a local machine through your router via an external address. See [[NAT_Loopback_Routers]] for a list of routers that support this feature.

==OpenSim in the Wild==
=== Are there test servers running OpenSim I can connect to? ===

Yes. Check out our [[Grid List]]! There are often many private servers up for testing. Hang out on the IRC channel (Freenode #opensim), and troll for URI's.

There are also several private organizations offering directories and search engines. They include:

*[http://www.hyperica.com Hyperica] -- a categorized directory of hypergrid-enabled OpenSim destinations, currently over 250 locations 
*[http://www.metaverseink.com MetaverseInk] -- ha key-word-based search engine for OpenSim grids, mostly those running the Diva Distro
*[http://www.gridhop.net GridHop] -- a list covering the major OpenSim grids, currently over 150 destinations accessible over hypergrid teleport
*[http://www.hgurl.com HGURL] -- a key-word-search database for all grid, all accessible via hypergrid (in progress API for acces to search engine and info in world).
*[http://www.thehypergates.com/ The HyperGates] -- The first dynamic, auto-updating HyperGrid directory for both HyperGrid 1.5 ( OpenSim 0.7.x ) and HyperGrid 1.0 ( OpenSim 0.6.x ) standalones & grids. Download the HyperGate from the site now and Join the HyperGate Network. The most reliable HyperGrid directory.

=== Are there any companies that will host my grid for me? ===

Yes there are dozens of independent OpenSim hosting providers. The following are not affiliated with OpenSimulator.org.

*[http://www.ReactionGrid.com/ ReactionGrid]
*[http://www.simhost.com SimHost]

More vendors listed here: [http://www.hypergridbusiness.com/opensim-hosting-providers/ Hypergrid Vendors Directory] -- a categorized directory of OpenSim vendors, currently listing about three dozen providers 

=== Can I teleport from the Linden Lab Second Life grid to my Sim? ===
No. In 2008 and 2009, there had been the connection to vaak grid, [http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/ which enabled us to teleport from Second Life over to an OpenSim grid] before LindenLab closing it. As of 2010, "The vaak grid is currently unavailable as we transition from OGP based services to VWRAP based services."([http://wiki.secondlife.com/wiki/Open_Grid_Public_Beta "Open Grid Public Beta" in Second Life Wiki])

==MySQL==
===How do I isolate and delete a user's Trash items in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE!

CAUTION: The Linux default directory for the MySQL database is /var/lib/mysql Many backup tools (e.g. backupPC) do NOT back up /var/*! Make certain that the database and not just the MySQL code (/usr/bin/mysql) is included in your nightly backups! The actual paths will be different for different operating systems and databases, but the problem is the same.

'''1.''' Locate the avatars UUID you wish to find the trash items of, in the '''users''' table 
This query will locate a specified users UUID: (replace User/Test with username/lastname)
<nowiki>SELECT `UUID` FROM `users` WHERE `username` LIKE 'User' AND `lastname` LIKE 'Test' LIMIT 0 , 30;</nowiki>
 
'''2.''' Use the avatars UUID to search the field_name '''AgentID''' in the '''inventoryFolders''' table, using '''Trash''' as the '''folderName''' to isolate the users Trash '''folderID''' 
This query will locate the users Trash folder entry: (replace 00000000-0000-0000-0000-000000000000 with UUID of user)
<nowiki>SELECT `folderID` FROM `inventoryfolders` WHERE `agentID` LIKE '00000000-0000-0000-0000-000000000000' AND `folderName` LIKE 'Trash'
LIMIT 0 , 30;</nowiki>
 
'''3.''' Use the '''folderID''' UUID obtained in the last query to find all of the trash items in the '''inventoryitems''' table, you can then delete them once you have isolated them. 
This query will locate the trash items of the avatar in question: (replace 00000000-0000-0000-0000-000000000000 with Trash folder UUID obtained in the last query)
<nowiki>SELECT * FROM `inventoryitems` WHERE `parentFolderID` LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 9999;</nowiki>
 
'''NOTE:''' These steps will not remove the associated assets from the assets table, just the items in the inventory '''inventoryitems''' table.

===How do I isolate and resolve duplicate inventory folder entries in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE! 

'''1.''' It's first a good idea to search for the affected avatars UUID in the '''inventoryFolders''' table to see the duplicate entries. When you see this, you'll see the problem of duplicate entries. The key here will be to find out which is being used. 

'''2.''' Upload a file inworld and name it something unique. This will isolate the UUID of your root folder that is being used (even though there are dups only one is being used) 

'''3.''' Search the '''inventoryitems''' table for your uniquely named item and locate it's '''parentFolderID''' 
This query will isolate the '''parentFolderID''' based on your search for the unique item (replace '''unique_name''' with your unique item name)
<nowiki>SELECT `parentFolderID` FROM `inventoryitems` WHERE `inventoryName` LIKE 'unique_name' LIMIT 0 , 30;</nowiki>

'''4.''' Check the '''inventoryfolders''' table against the '''parentFolderID''' UUID obtained in the last search. That is your root folder that is being used.. you can delete all duplicate entries that do not match that parentFolderID. In the end, you should only have one of each type (Trash, etc) 
This query will return all values that are NOT the parentID obtained in the last search. (replace 00000000-0000-0000-0000-000000000000 with the parentID located in step 3)
<nowiki>SELECT * FROM `inventoryfolders` WHERE `folderID` NOT LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 30;</nowiki>

==In World Questions==
=== Does in world scripting work yet? ===
Not fully implemented, but there is a lot of work going on here. Please see [[ScriptEngines]], [[LSL Status]] and [[OSSL Status]] for the latest info.

===Can I customize my avatar?===
Yes. In order to do this:
* Click the Inventory Button
* Create -> New Clothes -> Shirt, Pants, etc
* Create -> New Body Parts -> Hair, Shape, etc
* Edit those from your inventory
* Wear them

Your avatar doesn't always face a nice direction for doing this, so you'll need to use the camera operations to see your face for some of the modifications. This is a known issue, will be fixed in the future. Also, you'll need to rewear you parts once you first join the environment. Right now default appearance is always "Ruth".

===Why do I look like I gas cloud right after I did the the previous steps?===
Second Life eliminated Ruth from their client. The Ruth we see in OpenSim is our own attempt of a yoga teacher and not truly Second Life's Ruth. When you create a shirt, pants, skin and shape and wear them without changing any parameters, the Second Life Viewer understands you are not Ruth. Since Ruth is no more, you become a cloud of gas. To fix it, either change a parameter of one of them before wearing all 4, or, if you already are a gas cloud, right click one of these items in your inventory and click edit. That should bring up the edit appearance menus. Just move any sliders and voilá.

===I used [[XEngine]], but my recent update caused [[DotNetEngine]] to come on again===
There were some changes and you will need to change or create the line DefaultScriptEngine = "XEngine" in the startup section to get XEngine back. See [[ScriptEngines]]

===Why doesn't my world map update when I edit the terrain?===
There are three approaches depending on just how adventurous you want to be. From the least to the most adventurous:
* Wait two days. You will need to restart your sim at the end of the two days to get the updates.
* Exit the .xml file for the region. Change the value in the "lastmap_refresh" attribute to "0". You will need to restart the sim.
* Not for the faint of heart! Edit the "WorldMapModule.cs" file and change the "LazySaveGeneratedMaptile" method to change the "RefreshSeconds" value to something less than two days. Be sure to read the comments and understand why things are the way they are.

Once your terrain stabilizes, this won't be much of a problem, but it is nice to see the updates while you're furiously developing something.

===Why are my knees bent when I stand idle?===
This seems to be a result of the ODE Physics Engine on 64 bit systems. A fix is to edit OpenSim.ini and change the following line:
* av_capsule_standup_tensor_linux = 550000
to
* av_capsule_standup_tensor_linux = 1700000

Note that this line of code is under the [ODEPhysicsSettings] section of the OpenSim.ini file.

===when I create a new skin and shape, the thing goes bonkers creating new assets constantly===
you have not configured an asset cache

you need to configure either the cenome cache or the flotsam cache

without an asset cache, temporary assets can't be held which means they are continously rerequested

copy either config-include/CenomeMemoryAssetCache.ini.example, or the relevant flotsam file, to .ini edit and set it up for your needs then check GridCommon.ini or StandaloneCommon.ini uncomment the line for that cache

(standalone defaults to cenome grid to flotsam)

==Grid Mode==
=== After the shiny new grid is running, what is next? ===
* Make sure one can stop/restart UGA &S (sims). Check out any ordering issues of stop/restart UGA w/o stop/restart sim(s).
* Make sure one can add/delete both a region and a user from the database.
* Make sure it runs overnight and check it each morning by logging into 1 or 2 key sims.
* '<tt>tail -f userserver.log</tt>' and watch/understand the login process.
* Make sure when you logoff your system, you can log back on and get control of the UGAS consoles.

==Region Statistics on a Web Page==
===Information about your regions.===
Region statistics such as region name, avatar name, avatar position<x,y,z>, number of prims, and a lot of other information can be obtained on a web page by:
* Adding the following to the bottom of the [[OpenSim.ini]] file
[WebStats]
enabled=true
* Using a web browser and typing in the "Login URI" + "/SStats/" of your standalone server.
For example- <nowiki>http://127.0.0.1:9000/SStats/</nowiki>
The resulting web page is continually updated using AJAX, so there is no need to refresh the page to obtain current information. One possible use for this web page information would be to see who is logged on to the region in real time - without actually logging in. 
This web page provides region information similar to the kind generated by using various server console commands to obtain region statistics. See [[Server_Commands]]

== Misc ==
=== You guys like April 1st, eh? Looks like the joke is on us... ===
Yes, every year we've had a piece of non destructive code in the unstable, unreleased, upstream subversion tree. The source tree that is only designed for testers and developers. In each case it has shown something that is possible in OpenSim that most people might not have realized. In 2008 this was an avatar created entirely from a Region Module (no user), in 2009 it was making all users a giant (and I mean giant) stick bug avatar. There will be more in the future, don't worry. The developers seem to have a sense of humor.

==About OpenSim==
===What is OpenSim?===
OpenSim is a platform for operating a virtual world, and supports multiple independent regions connecting to a single centralized grid. This is somewhat similar to the web, where anyone can run their own web server, tied together through the internet. It can also be used to create a private grid, analogous to a private intranet.

===What is a region?===
A region is what you see when you log into OpenSim. It is the physical place (well, virtual physical space) where avatars move and interact. It is a square patch of land which may contain an island, mountains, a plain, buildings, etc., or just an ocean.

===What is the grid?===
The grid is the level that organizes the regions and their positions in the world, and handles things that need to exist across regions, such as a user's inventory. You can think of it as similar to the world map.

===What does ... mean?===
See [[Technical_Reference | OpenSim:Technical Reference]] for definitions of some terms commonly used in OpenSim.

==Configuring OpenSim==
First, read [[OpenSim Configuration]].

MariaKorolov: /* Are there test servers running OpenSim I can connect to? */

{{Template:Quicklinks}}
 

[[Category:Users]]
==About OpenSim==
===What is OpenSim?===
OpenSim is a platform for operating a virtual world, and supports multiple independent regions connecting to a single centralized grid. This is somewhat similar to the web, where anyone can run their own web server, tied together through the internet. It can also be used to create a private grid, analogous to a private intranet.

===What is a region?===
A region is what you see when you log into OpenSim. It is the physical place (well, virtual physical space) where avatars move and interact. It is a square patch of land which may contain an island, mountains, a plain, buildings, etc., or just an ocean.

===What is the grid?===
The grid is the level that organizes the regions and their positions in the world, and handles things that need to exist across regions, such as a user's inventory. You can think of it as similar to the world map.

===What does ... mean?===
See [[Technical_Reference | OpenSim:Technical Reference]] for definitions of some terms commonly used in OpenSim.

==Configuring OpenSim==
First, read [[OpenSim Configuration]].
===Where can I get a new UUID for my sim config?===
* See [[OpenSim Configuration]]

===Can I run multiple regions with OpenSim?===
* See [[OpenSim Configuration]]

===What databases can be used with OpenSim?===
* See [[OpenSim Configuration]]

==Running OpenSim==

===I get a bunch of ERROR: There was an error while scanning assembly:... 
errors on startup, but OpenSim appears to run normally. Is this a problem?===
No. These errors are being put out by the third party plugin scanning code. As we have it scanning the entire bin/ directory, it picks up dlls which don't have the correct information to be scanned, and so puts out this error. Don't worry about it :)

For the record, the current set of errors are

ERROR: There was an error while scanning assembly: /home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/PhysX-wrapper.dll (Could not load file or assembly '/home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/PhysX-wrapper.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.)

ERROR: There was an error while scanning assembly: /home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/ode-debug.dll (Could not load file or assembly '/home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/ode-debug.dll' or one of its dependencies.

ERROR: There was an error while scanning assembly: /home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/sqlite3.dll (Could not load file or assembly '/home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/sqlite3.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.)

===Errors about modules not found and RegionBanListItem could not be loaded===

This is caused if you upgrade from trunk through svn and copy new files in the same directory.
To solve these errors during the startup of opensim.exe remove the following files from your bin folder:

OpenSIm.DataStore.MSSQL.dll

OpenSIm.DataStore.MSSQL.dll.mdm

===Errors from incomplete data migrations===

This can happen during version upgrades if for some reason a database migration fails when there is a change in the way OpenSim stores data.

You may see errors on the OpenSim console like:

[LLOGIN SERVICE]: Exception processing login for [username]: MySql.Data.MySqlClient.MySqlException: Table 'opensim.UserAccounts' doesn't exist
at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000]
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000] at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000]
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000]

In this case the 'users' table had not been migrated to the 'UserAccounts' table which OpenSim was expecting, also resulting in the viewerside error:

Login Failed
Error generating Login Response

I solved by fixing the filesystem permissions that were causing the migration to fail (on my Linux box '/var/lib/mysql/...' had got itself messed up), then dropping the 'migration' table and running the server again (from the [non-critical] migration warnings encountered there was probably a more precise way to do this, but I was fully backed up so I did it quick-and-dirty). Other than loosing terrain data refs. and current shape/clothing/attachment data (easily restored in-sim) all was now good for me.

==OpenSim in the Wild==
=== Are there test servers running OpenSim I can connect to? ===

Yes. Check out our [[Grid List]]! There are often many private servers up for testing. Hang out on the IRC channel (Freenode #opensim), and troll for URI's.

There are also several private organizations offering directories and search engines. They include:

*[http://www.hyperica.com Hyperica] -- a categorized directory of hypergrid-enabled OpenSim destinations, currently over 250 locations 
*[http://www.metaverseink.com MetaverseInk] -- ha key-word-based search engine for OpenSim grids, mostly those running the Diva Distro
*[http://www.gridhop.net GridHop] -- a list covering the major OpenSim grids, currently over 150 destinations accessible over hypergrid teleport
*[http://www.hgurl.com HGURL] -- a key-word-search database covering mostly destinations on the French-language FrancoGrid and related grids, all accessible via hypergrid
*[[Thehypergates.com|The Hypergates]] -- a directory of hypergrid-enabled destinations part of a hypergate teleportation network

=== Can I teleport from the Linden Lab Second Life grid to my Sim? (updated!)===
Yes and No, Since the new public beta, launched on july 31th 2008 by Linden Lab, it is now possible to connect opensim servers/regions with the Second life grid, however this is not intended for regular users. 
NOTE: currently it ONLY works with the preview/beta grid of second life, not the main grid.) 
It's in an early development stage and thus geared towards developers of virtual world/techniques, and is all but easy to setup. Furthermore, when an avatar is hopping from an SL region to an Opensim region, the avatar will be "ruthed", meaning it will be the default Secondlife avatar. NO assets (incl, shapes, skins, clothing etc) are tranfered during teleport, hence you wont have access to them, on the other grid. The beta test, is currently focussing on Teleportation between grids mainly. In the future, it should be possible to teleport WITH asset tranfers. But that wont be happening any time soon. If you want to try it out, read this page for more info on how to get started (with all the risks involved, don't say i didn't warn you): [http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/ http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/] 
For normal operation, stick to the regular versions of opensim.

==MySQL==
===How do I isolate and delete a user's Trash items in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE!

CAUTION: The Linux default directory for the MySQL database is /var/lib/mysql Many backup tools (e.g. backupPC) do NOT back up /var/*! Make certain that the database and not just the MySQL code (/usr/bin/mysql) is included in your nightly backups! The actual paths will be different for different operating systems and databases, but the problem is the same.

'''1.''' Locate the avatars UUID you wish to find the trash items of, in the '''users''' table 
This query will locate a specified users UUID: (replace User/Test with username/lastname)
<nowiki>SELECT `UUID` FROM `users` WHERE `username` LIKE 'User' AND `lastname` LIKE 'Test' LIMIT 0 , 30;</nowiki>
 
'''2.''' Use the avatars UUID to search the field_name '''AgentID''' in the '''inventoryFolders''' table, using '''Trash''' as the '''folderName''' to isolate the users Trash '''folderID''' 
This query will locate the users Trash folder entry: (replace 00000000-0000-0000-0000-000000000000 with UUID of user)
<nowiki>SELECT `folderID` FROM `inventoryfolders` WHERE `agentID` LIKE '00000000-0000-0000-0000-000000000000' AND `folderName` LIKE 'Trash'
LIMIT 0 , 30;</nowiki>
 
'''3.''' Use the '''folderID''' UUID obtained in the last query to find all of the trash items in the '''inventoryitems''' table, you can then delete them once you have isolated them. 
This query will locate the trash items of the avatar in question: (replace 00000000-0000-0000-0000-000000000000 with Trash folder UUID obtained in the last query)
<nowiki>SELECT * FROM `inventoryitems` WHERE `parentFolderID` LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 9999;</nowiki>
 
'''NOTE:''' These steps will not remove the associated assets from the assets table, just the items in the inventory '''inventoryitems''' table.

===How do I isolate and resolve duplicate inventory folder entries in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE! 

'''1.''' It's first a good idea to search for the affected avatars UUID in the '''inventoryFolders''' table to see the duplicate entries. When you see this, you'll see the problem of duplicate entries. The key here will be to find out which is being used. 

'''2.''' Upload a file inworld and name it something unique. This will isolate the UUID of your root folder that is being used (even though there are dups only one is being used) 

'''3.''' Search the '''inventoryitems''' table for your uniquely named item and locate it's '''parentFolderID''' 
This query will isolate the '''parentFolderID''' based on your search for the unique item (replace '''unique_name''' with your unique item name)
<nowiki>SELECT `parentFolderID` FROM `inventoryitems` WHERE `inventoryName` LIKE 'unique_name' LIMIT 0 , 30;</nowiki>

'''4.''' Check the '''inventoryfolders''' table against the '''parentFolderID''' UUID obtained in the last search. That is your root folder that is being used.. you can delete all duplicate entries that do not match that parentFolderID. In the end, you should only have one of each type (Trash, etc) 
This query will return all values that are NOT the parentID obtained in the last search. (replace 00000000-0000-0000-0000-000000000000 with the parentID located in step 3)
<nowiki>SELECT * FROM `inventoryfolders` WHERE `folderID` NOT LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 30;</nowiki>

==In World Questions==
=== Does in world scripting work yet? ===
Not fully implemented, but there is a lot of work going on here. Please see [[ScriptEngines]], [[LSL Status]] and [[OSSL Status]] for the latest info.

===Why do I walk through objects?===
Basicphysics doesn't support collisions between objects (just between you and the ground). There is active work on other [[PhysicsEngines | physics engines]] for OpenSim, the one that does most of the job and is most stable is the ODE (Open Dynamics Engine), which can be configured for use in OpenSim.ini.

===Can I customize my avatar?===
Yes. In order to do this:
* Click the Inventory Button
* Create -> New Clothes -> Shirt, Pants, etc
* Create -> New Body Parts -> Hair, Shape, etc
* Edit those from your inventory
* Wear them

Your avatar doesn't always face a nice direction for doing this, so you'll need to use the camera operations to see your face for some of the modifications. This is a known issue, will be fixed in the future. Also, you'll need to rewear you parts once you first join the environment. Right now default appearance is always "Ruth".

===Why do I look like I gas cloud right after I did the the previous steps?===
Second Life eliminated Ruth from their client. The Ruth we see in OpenSim is our own attempt of a yoga teacher and not truly Second Life's Ruth. When you create a shirt, pants, skin and shape and wear them without changing any parameters, the Second Life Viewer understands you are not Ruth. Since Ruth is no more, you become a cloud of gas. To fix it, either change a parameter of one of them before wearing all 4, or, if you already are a gas cloud, right click one of these items in your inventory and click edit. That should bring up the edit appearance menus. Just move any sliders and voilá.

===Why don't my terrain settings and prims stay through restarts?===
You haven't set it up to use a database. See [[OpenSim_Database_support|OpenSim Database support]] for info on how to set it up to use a database. (SqLite is the easiest of these to set up and should probably be used by anyone unfamiliar with any of the options).

===I used XEngine, but my recent update caused DotNetEngine to come on again===
There were some changes and you will need to change or create the line DefaultScriptEngine = "XEngine" in the startup section to get XEngine back. See [[ScriptEngines]]

===Why doesn't my world map update when I edit the terrain?===
There are three approaches depending on just how adventurous you want to be. From the least to the most adventurous:
* Wait two days. You will need to restart your sim at the end of the two days to get the updates.
* Exit the .xml file for the region. Change the value in the "lastmap_refresh" attribute to "0". You will need to restart the sim.
* Not for the faint of heart! Edit the "WorldMapModule.cs" file and change the "LazySaveGeneratedMaptile" method to change the "RefreshSeconds" value to something less than two days. Be sure to read the comments and understand why things are the way they are.

Once your terrain stabilizes, this won't be much of a problem, but it is nice to see the updates while you're furiously developing something.

===Why are my knees bent when I stand idle?===
This seems to be a result of the ODE Physics Engine on 64 bit systems. A fix is to edit OpenSim.ini and change the following line:
* av_capsule_standup_tensor_linux = 550000
to
* av_capsule_standup_tensor_linux = 1700000

Note that this line of code is under the [ODEPhysicsSettings] section of the OpenSim.ini file.

===when I create a new skin and shape, the thing goes bonkers creating new assets constantly===
you have not configured an asset cache

you need to configure either the cenome cache or the flotsam cache

without an asset cache, temporary assets can't be held which means they are continously rerequested

copy either config-include/CenomeMemoryAssetCache.ini.example, or the relevant flotsam file, to .ini edit and set it up for your needs then check GridCommon.ini or StandaloneCommon.ini uncomment the line for that cache

(standalone defaults to cenome grid to flotsam)

==Grid Mode==
=== After the shiny new grid is running, what is next? ===
* Make sure one can stop/restart UGA &S (sims). Check out any ordering issues of stop/restart UGA w/o stop/restart sim(s).
* Make sure one can add/delete both a region and a user from the database.
* Make sure it runs overnight and check it each morning by logging into 1 or 2 key sims.
* '<tt>tail -f userserver.log</tt>' and watch/understand the login process.
* Make sure when you logoff your system, you can log back on and get control of the UGAS consoles.

==Region Statistics on a Web Page==
===Information about your regions.===
Region statistics such as region name, avatar name, avatar position<x,y,z>, number of prims, and a lot of other information can be obtained on a web page by:
* Adding the following to the bottom of the [[Technical Reference/terms/OpenSim.ini | OpenSim.ini ]] file
[WebStats]
enabled=true
* Using a web browser and typing in the "Login URI" + "/SStats/" of your standalone server.
For example- <nowiki>http://127.0.0.1:9000/SStats/</nowiki>
The resulting web page is continually updated using AJAX, so there is no need to refresh the page to obtain current information. One possible use for this web page information would be to see who is logged on to the region in real time - without actually logging in. 
This web page provides region information similar to the kind generated by using various server console commands to obtain region statistics. See [[Technical_Reference/Server_Commands | Server_Commands]]

== Misc ==
=== You guys like April 1st, eh? Looks like the joke is on us... ===
Yes, every year we've had a piece of non destructive code in the unstable, unreleased, upstream subversion tree. The source tree that is only designed for testers and developers. In each case it has shown something that is possible in OpenSim that most people might not have realized. In 2008 this was an avatar created entirely from a Region Module (no user), in 2009 it was making all users a giant (and I mean giant) stick bug avatar. There will be more in the future, don't worry. The developers seem to have a sense of humor.

==About OpenSim==
===What is OpenSim?===
OpenSim is a platform for operating a virtual world, and supports multiple independent regions connecting to a single centralized grid. This is somewhat similar to the web, where anyone can run their own web server, tied together through the internet. It can also be used to create a private grid, analogous to a private intranet.

===What is a region?===
A region is what you see when you log into OpenSim. It is the physical place (well, virtual physical space) where avatars move and interact. It is a square patch of land which may contain an island, mountains, a plain, buildings, etc., or just an ocean.

===What is the grid?===
The grid is the level that organizes the regions and their positions in the world, and handles things that need to exist across regions, such as a user's inventory. You can think of it as similar to the world map.

===What does ... mean?===
See [[Technical_Reference | OpenSim:Technical Reference]] for definitions of some terms commonly used in OpenSim.

==Configuring OpenSim==
First, read [[OpenSim Configuration]].
===Where can I get a new UUID for my sim config?===
* See [[OpenSim Configuration]]

===Can I run multiple regions with OpenSim?===
* See [[OpenSim Configuration]]

===What databases can be used with OpenSim?===
* See [[OpenSim Configuration]]

==Running OpenSim==

===I get a bunch of ERROR: There was an error while scanning assembly:... 
errors on startup, but OpenSim appears to run normally. Is this a problem?===
No. These errors are being put out by the third party plugin scanning code. As we have it scanning the entire bin/ directory, it picks up dlls which don't have the correct information to be scanned, and so puts out this error. Don't worry about it :)

For the record, the current set of errors are

ERROR: There was an error while scanning assembly: /home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/PhysX-wrapper.dll (Could not load file or assembly '/home/caseyj/jc/it/v/virtual-worlds/second-life/servers/opensim/src/opensim-svn-minim/bin/PhysX-wrapper.dll' or one of its dependencies.

An attempt was made to load a program with an incorrect format.)

===Errors about modules not found and RegionBanListItem could not be loaded===

This is caused if you upgrade from trunk through svn and copy new files in the same directory.
To solve these errors during the startup of opensim.exe remove the following files from your bin folder:

OpenSIm.DataStore.MSSQL.dll

OpenSIm.DataStore.MSSQL.dll.mdm

===Errors from incomplete data migrations===

This can happen during version upgrades if for some reason a database migration fails when there is a change in the way OpenSim stores data.

You may see errors on the OpenSim console like:

[LLOGIN SERVICE]: Exception processing login for [username]: MySql.Data.MySqlClient.MySqlException: Table 'opensim.UserAccounts' doesn't exist
at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000]
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000] at MySql.Data.MySqlClient.MySqlStream.OpenPacket () [0x00000]
at MySql.Data.MySqlClient.NativeDriver.ReadResult (System.UInt64& affectedRows, System.Int64& lastInsertId) [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.GetResultSet () [0x00000]
at MySql.Data.MySqlClient.MySqlDataReader.NextResult () [0x00000]

In this case the 'users' table had not been migrated to the 'UserAccounts' table which OpenSim was expecting, also resulting in the viewerside error:

Login Failed
Error generating Login Response

I solved by fixing the filesystem permissions that were causing the migration to fail (on my Linux box '/var/lib/mysql/...' had got itself messed up), then dropping the 'migration' table and running the server again (from the [non-critical] migration warnings encountered there was probably a more precise way to do this, but I was fully backed up so I did it quick-and-dirty). Other than loosing terrain data refs. and current shape/clothing/attachment data (easily restored in-sim) all was now good for me.

==OpenSim in the Wild==
===Are there test servers running OpenSim I can connect to?===
Yes. Check out our [[Grid List]]! There are often many private servers up for testing. Hang out on the IRC channel (Freenode #opensim), and troll for URI's.

There are also several private organizations offering directories and search engines. They include:

Hyperica -- http://www.hyperica.com -- a categorized directory of hypergrid-enabled OpenSim destinations, currently over 250 locations
MetaverseInk -- http://www.metaverseink.com -- a key-word-based search engine for OpenSim grids, mostly those running the Diva Distro
GridHop -- http://www.gridhop.net -- a list covering the major OpenSim grids, currently over 150 destinations accessible over hypergrid teleport
HGURL -- a key-word-search database covering mostly destinations on the French-language FrancoGrid and related grids, all accessible via hypergrid
The Hypergates -- a directory of hypergrid-enabled destinations part of a hypergate teleportation network

=== Can I teleport from the Linden Lab Second Life grid to my Sim? (updated!)===
Yes and No, Since the new public beta, launched on july 31th 2008 by Linden Lab, it is now possible to connect opensim servers/regions with the Second life grid, however this is not intended for regular users. 
NOTE: currently it ONLY works with the preview/beta grid of second life, not the main grid.) 
It's in an early development stage and thus geared towards developers of virtual world/techniques, and is all but easy to setup. Furthermore, when an avatar is hopping from an SL region to an Opensim region, the avatar will be "ruthed", meaning it will be the default Secondlife avatar. NO assets (incl, shapes, skins, clothing etc) are tranfered during teleport, hence you wont have access to them, on the other grid. The beta test, is currently focussing on Teleportation between grids mainly. In the future, it should be possible to teleport WITH asset tranfers. But that wont be happening any time soon. If you want to try it out, read this page for more info on how to get started (with all the risks involved, don't say i didn't warn you): [http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/ http://blog.secondlife.com/2008/07/31/open-grid-public-beta-begins-today/] 
For normal operation, stick to the regular versions of opensim.

==MySQL==
===How do I isolate and delete a user's Trash items in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE!

CAUTION: The Linux default directory for the MySQL database is /var/lib/mysql Many backup tools (e.g. backupPC) do NOT back up /var/*! Make certain that the database and not just the MySQL code (/usr/bin/mysql) is included in your nightly backups! The actual paths will be different for different operating systems and databases, but the problem is the same.

'''1.''' Locate the avatars UUID you wish to find the trash items of, in the '''users''' table 
This query will locate a specified users UUID: (replace User/Test with username/lastname)
<nowiki>SELECT `UUID` FROM `users` WHERE `username` LIKE 'User' AND `lastname` LIKE 'Test' LIMIT 0 , 30;</nowiki>
 
'''2.''' Use the avatars UUID to search the field_name '''AgentID''' in the '''inventoryFolders''' table, using '''Trash''' as the '''folderName''' to isolate the users Trash '''folderID''' 
This query will locate the users Trash folder entry: (replace 00000000-0000-0000-0000-000000000000 with UUID of user)
<nowiki>SELECT `folderID` FROM `inventoryfolders` WHERE `agentID` LIKE '00000000-0000-0000-0000-000000000000' AND `folderName` LIKE 'Trash'
LIMIT 0 , 30;</nowiki>
 
'''3.''' Use the '''folderID''' UUID obtained in the last query to find all of the trash items in the '''inventoryitems''' table, you can then delete them once you have isolated them. 
This query will locate the trash items of the avatar in question: (replace 00000000-0000-0000-0000-000000000000 with Trash folder UUID obtained in the last query)
<nowiki>SELECT * FROM `inventoryitems` WHERE `parentFolderID` LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 9999;</nowiki>
 
'''NOTE:''' These steps will not remove the associated assets from the assets table, just the items in the inventory '''inventoryitems''' table.

===How do I isolate and resolve duplicate inventory folder entries in a MySQL grid database?===
NOTE: BACK UP YOUR DATABASE! 

'''1.''' It's first a good idea to search for the affected avatars UUID in the '''inventoryFolders''' table to see the duplicate entries. When you see this, you'll see the problem of duplicate entries. The key here will be to find out which is being used. 

'''2.''' Upload a file inworld and name it something unique. This will isolate the UUID of your root folder that is being used (even though there are dups only one is being used) 

'''3.''' Search the '''inventoryitems''' table for your uniquely named item and locate it's '''parentFolderID''' 
This query will isolate the '''parentFolderID''' based on your search for the unique item (replace '''unique_name''' with your unique item name)
<nowiki>SELECT `parentFolderID` FROM `inventoryitems` WHERE `inventoryName` LIKE 'unique_name' LIMIT 0 , 30;</nowiki>

'''4.''' Check the '''inventoryfolders''' table against the '''parentFolderID''' UUID obtained in the last search. That is your root folder that is being used.. you can delete all duplicate entries that do not match that parentFolderID. In the end, you should only have one of each type (Trash, etc) 
This query will return all values that are NOT the parentID obtained in the last search. (replace 00000000-0000-0000-0000-000000000000 with the parentID located in step 3)
<nowiki>SELECT * FROM `inventoryfolders` WHERE `folderID` NOT LIKE '00000000-0000-0000-0000-000000000000' LIMIT 0 , 30;</nowiki>

==In World Questions==
=== Does in world scripting work yet? ===
Not fully implemented, but there is a lot of work going on here. Please see [[ScriptEngines]], [[LSL Status]] and [[OSSL Status]] for the latest info.

===Why do I walk through objects?===
Basicphysics doesn't support collisions between objects (just between you and the ground). There is active work on other [[PhysicsEngines | physics engines]] for OpenSim, the one that does most of the job and is most stable is the ODE (Open Dynamics Engine), which can be configured for use in OpenSim.ini.

===Can I customize my avatar?===
Yes. In order to do this:
* Click the Inventory Button
* Create -> New Clothes -> Shirt, Pants, etc
* Create -> New Body Parts -> Hair, Shape, etc
* Edit those from your inventory
* Wear them

Your avatar doesn't always face a nice direction for doing this, so you'll need to use the camera operations to see your face for some of the modifications. This is a known issue, will be fixed in the future. Also, you'll need to rewear you parts once you first join the environment. Right now default appearance is always "Ruth".

===Why do I look like I gas cloud right after I did the the previous steps?===
Second Life eliminated Ruth from their client. The Ruth we see in OpenSim is our own attempt of a yoga teacher and not truly Second Life's Ruth. When you create a shirt, pants, skin and shape and wear them without changing any parameters, the Second Life Viewer understands you are not Ruth. Since Ruth is no more, you become a cloud of gas. To fix it, either change a parameter of one of them before wearing all 4, or, if you already are a gas cloud, right click one of these items in your inventory and click edit. That should bring up the edit appearance menus. Just move any sliders and voilá.

===Why don't my terrain settings and prims stay through restarts?===
You haven't set it up to use a database. See [[OpenSim_Database_support|OpenSim Database support]] for info on how to set it up to use a database. (SqLite is the easiest of these to set up and should probably be used by anyone unfamiliar with any of the options).

===I used XEngine, but my recent update caused DotNetEngine to come on again===
There were some changes and you will need to change or create the line DefaultScriptEngine = "XEngine" in the startup section to get XEngine back. See [[ScriptEngines]]

===Why doesn't my world map update when I edit the terrain?===
There are three approaches depending on just how adventurous you want to be. From the least to the most adventurous:
* Wait two days. You will need to restart your sim at the end of the two days to get the updates.
* Exit the .xml file for the region. Change the value in the "lastmap_refresh" attribute to "0". You will need to restart the sim.
* Not for the faint of heart! Edit the "WorldMapModule.cs" file and change the "LazySaveGeneratedMaptile" method to change the "RefreshSeconds" value to something less than two days. Be sure to read the comments and understand why things are the way they are.

Once your terrain stabilizes, this won't be much of a problem, but it is nice to see the updates while you're furiously developing something.

===Why are my knees bent when I stand idle?===
This seems to be a result of the ODE Physics Engine on 64 bit systems. A fix is to edit OpenSim.ini and change the following line:
* av_capsule_standup_tensor_linux = 550000
to
* av_capsule_standup_tensor_linux = 1700000

Note that this line of code is under the [ODEPhysicsSettings] section of the OpenSim.ini file.

===when I create a new skin and shape, the thing goes bonkers creating new assets constantly===
you have not configured an asset cache

you need to configure either the cenome cache or the flotsam cache

without an asset cache, temporary assets can't be held which means they are continously rerequested

copy either config-include/CenomeMemoryAssetCache.ini.example, or the relevant flotsam file, to .ini edit and set it up for your needs then check GridCommon.ini or StandaloneCommon.ini uncomment the line for that cache

(standalone defaults to cenome grid to flotsam)

==Grid Mode==
=== After the shiny new grid is running, what is next? ===
* Make sure one can stop/restart UGA &S (sims). Check out any ordering issues of stop/restart UGA w/o stop/restart sim(s).
* Make sure one can add/delete both a region and a user from the database.
* Make sure it runs overnight and check it each morning by logging into 1 or 2 key sims.
* '<tt>tail -f userserver.log</tt>' and watch/understand the login process.
* Make sure when you logoff your system, you can log back on and get control of the UGAS consoles.

==Region Statistics on a Web Page==
===Information about your regions.===
Region statistics such as region name, avatar name, avatar position<x,y,z>, number of prims, and a lot of other information can be obtained on a web page by:
* Adding the following to the bottom of the [[Technical Reference/terms/OpenSim.ini | OpenSim.ini ]] file
[WebStats]
enabled=true
* Using a web browser and typing in the "Login URI" + "/SStats/" of your standalone server.
For example- <nowiki>http://127.0.0.1:9000/SStats/</nowiki>
The resulting web page is continually updated using AJAX, so there is no need to refresh the page to obtain current information. One possible use for this web page information would be to see who is logged on to the region in real time - without actually logging in. 
This web page provides region information similar to the kind generated by using various server console commands to obtain region statistics. See [[Technical_Reference/Server_Commands | Server_Commands]]

== Misc ==
=== You guys like April 1st, eh? Looks like the joke is on us... ===
Yes, every year we've had a piece of non destructive code in the unstable, unreleased, upstream subversion tree. The source tree that is only designed for testers and developers. In each case it has shown something that is possible in OpenSim that most people might not have realized. In 2008 this was an avatar created entirely from a Region Module (no user), in 2009 it was making all users a giant (and I mean giant) stick bug avatar. There will be more in the future, don't worry. The developers seem to have a sense of humor.
