[Opensim-users] Opensim-users Digest, Vol 74, Issue 4

[Fred]

You edit Opensim.ini, the var you need is regionload_regionsdir, none of 
you other edits do anything for you.  You can make it so only one 
Opensim exe and folder is used across all simulators at the same time. I 
do niot know about Linux pure code sharing, but Windows will only load 
the program into memory once no matter how many opensims you run.

In DreamGrid, all instances run out of that one updatable folder.  I 
just move Opensim.ini out and the edits in it move more files.  It is 
AGPL, and the souce code is at /Outworldz at Github.

Maptiles and Scriptengines never gets updated, and can be shared.  
Likewise there is no  GridHypergrid.ini or GridCommon.ini in an update. 
So there is zrro need to move them.

You do need to rename or move ossEnable.ini.  I just rename it in the 
Opensim.ini include to get the renamed file.

Edits  made to Opensim.ini listed below.  Then I put Opensim.ini in a 
opensim\bin\Regions folder for each Instance I want to run. I can thus 
run s many different phsyics engines or settings as a I want for each 
Instance.  Dreamgrid pulls using code extra INI settings for 
Opensim.,ini from each Region file and writes the OPensim.ini for you.   
You could do this with grep and sed on Linux.

The name of each Instance (Dos box or bash shell) goes in the CONST 
section as "RegionFolderName", such as bin\Regions

[CONST}

;# used by the one-exe-per-instance logic. This becomes the folder for 
the regions file.RegionFolderName=Welcome

The above edit to Openim.ini and the following line results in the 
Region running out of file being in bin\Regions\Welcome, 
bin\Regions\Some Other Sim, and so on, where I put the Opensim.ini,  a 
folder for Datasnapshot, the Process ID, and both logs as they are 
specific to that Instance.

[Startup]

; move the region ini
regionload_regionsdir=./Regions/${Const|RegionFolderName}/Region/

;I also move the PID file:
PIDFile="./Regions/${Const|RegionFolderName}/PID.pid"

;Move Datasnapshot as it is created by each region, and thus cannot be 
written at the same time by two processes
snapshot_cache_directory="./Regions/${Const|RegionFolderName}/DataSnapshot"

Logs cannot be shared among instances, as multiple writes to the same 
file are not possible. DreamGrid fixes this by starting each instance by 
exporting a variable and getting that into the Opensim.exe.config file

Everywhere you have <file value=".\OpenSim.log" />   or other file in 
the Opensim.exe.config XML file add the path ${OSIM_LOGPATH}. Opensim 
knows how tand  read this.

<file value="${OSIM_LOGPATH}\OpenSim.log" /> and <file 
value="${OSIM_LOGPATH}\OpenSimStats.log"/>

One other tip:  set the logging level programmatically by another 
environment variable in the various places in Opensim.ini.config

<level value="${OSIM_LOGLEVEL}" />

Now you can use an environment variable such as OSIM_LOGLEVEL=ERROR  or 
ALL or WARN etc, to set it across all instances.

Launch Opensim with something like this windows file 'go.bat' as in 'go 
Welcome<enter>'

The key line is

OpenSim.exe -inidirectory="Regions/%SimName%"

On Linux I think this name is  $1.

Windows/DOS format:

@echo Loading %1
cd bin
set SimName=%1
set OSIM_LOGPATH = "%~dp0\bin\Regions\%SimName%"
OpenSim.exe -inidirectory="Regions/%SimName%"
cd ..
echo %SimName% has exited.

This can be easily ported to Linux bash with EXPORT.

tl;dr, all you neeed is regionload_regionsdir
