FS Assets

FSAssets ist für Grids vorgesehen, bei denen die Größe der Datenbank voraussichtlich 50 GB überschreitet. Diese Option speichert die Assets im Dateisystem im Gegensatz zum Standarddienst, der Assets als Blobs in der Datenbank speichert. Diese Option bietet auch Deduplizierungsfunktionen. Jedes Asset wird gehasht, wenn es zur Speicherung empfangen wird. Wenn das Asset bereits vorhanden ist, wird der Asset-Service mit der vorhandenen Datei verknüpft, anstatt zwei Kopien zu speichern. Einzelpersonen erreichen sehr schnell ein Inventar der Größe 12 GB im laufe der zeit erhöht sich das ganze meist auf 18 GB pro Benutzer, es gibt aber ausnahmen wo einzelne Personen schon 50 GB erreichen.

Konfigurationsoptionen

Öffnen Sie zum Aktivieren von FSAssets die Robust.ini oder Robust.HG.ini, je nachdem, ob Sie ein Standard- oder Hypergrid- fähiges Grid betreiben, und suchen Sie den Abschnitt AssetService. Ändern Sie das LocalServiceModule in FSAssetService wie folgt:

LocalServiceModule = "OpenSim.Services.FSAssetService.dll:FSAssetConnector"

Also uncomment the following required settings, these are specific to FSAssets:

BaseDirectory = "./fsassets/data"
SpoolDirectory = "./fsassets/tmp"

The following are optional FSAsset config options:

;FallbackService = "OpenSim.Services.AssetService.dll:AssetService"
;DaysBetweenAccessTimeUpdates = 30

;StorageProvider = ""
;ConnectionString = ""
;Realm = "fsassets"

• BaseDirectory

This is the folder in which the asset data will be saved.

• SpoolDirectory

The spool directory is a folder used for temporary storage while the asset is hashed and compressed before it gets moved to the BaseDirectory. This must be on the same file system as the base directory.

• FallbackService

If you are upgrading from the default asset service, uncomment this and set the default asset connector. This will allow FSAssets to retrieve an existing asset from the old service and add it to the BaseDirectory. The fallback service is checked when an asset is requested but not found by FSAssets.

• DaysBetweenAccessTimeUpdates

By default, the access time is updated each time an asset is requested. This option can be used to skip this update for assets that already have a recent access time and reduce calls to the database.

• StorageProvider

To change where the metadata is saved you can set a specific storage provider and connection string. If this is disabled, the default storage provider given in the database section will be used to save metadata.

• ConnectionString

DB connection string for the optional StorageProvider mentioned above.

• Realm

The table name to save metadata in the database. Default is 'fsassets'

Migration

While FSAssets will use the FallBackService if set, to convert any existing assets when they are requested and not found, this will not automatically convert all the old assets to the new service. To convert all assets from the default service there is a console command provided:

 import <conn> <table> [<start> <count>]

The import command expects a database connection string and the name of the legacy asset table to be passed as parameters. The following example shows how to start the import process for a MySQL database, just change the connection details to match your database schema, username and password:

 import "Data Source=localhost;Database=SCHEMA;User ID=USER;Password=PASS;Old Guids=true;" assets

Depending on the size of your existing assets table, the import process will take some time to complete. The optional parameters, start and count allow you to specify the position and number of rows to convert.

If the import command fails with a timeout error., add "command timeout=300;" to the connection string:

import "Data Source=localhost;Port=3306;Database=Robust;User ID=SomeRobustuser;Password=Somerobustpassword;Old Guids=true;Command Timeout=300;" assets

The timeout is in minutes, and the default is only 30 seconds.

Hypergrid Assets

If your grid has hypergrid enabled, you probably have it setup to use the HGAssetService for sharing assets with other grids. In this situation you will need to change the HGAssetService section of your Robust.ini to point to the FSAssets version of the HGAssetService known as HGFSAssetService.

To enable the HGFSAssetService, find the HGAssetService section of your Robust.ini, the LocalServiceModule should be changed to:

 LocalServiceModule = "OpenSim.Services.HypergridService.dll:HGFSAssetService"
