Second report:
---------------------------------
- Created a new assembly: Opensim.Framework.Data.Hibernate.
- Opensim.ini: new configuration ===> asset_database = "hibernate"
Every other server,
example: inventory_plugin = "OpenSim.Framework.Data.Hibernate.dll"
* I don't want to do deep changes now
so it is implemented as a plugin like the others (mysql, sqlite...)
- Changes in database: minimums by now, only some primary keys created and
TEXT fields changed to VARCHAR
- All the database objects mapped to hibernate.
- Tested on MySQL. When completed will be tested in sqlite & mssql (maybe
oracle if I have time)
- Status: Opensim starts up step by step until
RegionApplicationBase.SetupScene. I have stopped (I'm very tired :-P, today
I coded 10 hours w/o rest ) inscene.performParcelPrimCountUpdate();
Well, seems that is quite easy to make the change, but is really really
really sloooooooow. I hope in 5 or 6 days could have a stable server, then I
will upload the files and documentation where you tell me.
