Hello.
Well... I'm using "Orion/1.5.2 (build 10460)" for reasons other than the
beans.
Well actually I do need more that 10 million rows. No, they are not
created withing one and the same transaction. Each one is created in a
different transaction (the code I posted was an excerpt of a stand-alone
client using com.evermind.server.rmi.RMIInitialContextFactory.
The database itself has no problems with a 1 million rows, but the
container does not passivate/clear/rele4ase the beans with time. They keep
growing and growing. The test beans had only an Integer primary key and no
data fields at all. The "real-life" beans will hold 1-2K data. You can see
the problem... 10K beans will be around 20MB data only. Too much for me.
I tried some tune-up settings, but could not get any results except with
the 'exclusive-write-access="false"', but in that case I get only one bean
generated, and that shits the hell out of me. I just need to set some
sensible time-out value, but neither instance-cache-timeout, nor
validity-timeout, nor pool-cache-timeout, nor max-instances did the job for
me. Non of these changed the logics. If the exclusive-write-access is true,
a bean instance gets generated every time I create an entity. If set to
false I get enormous lag for using the beans. That is not good. Isn't there
any setting, that can tell orion to flush the bean instances every let's say
10 seconds?
Thanks for the help anyway. A food for thought.
Looking forward for some helper settings.
Lachezar.
