Re: InstantDB: RMIJDBC-memory problem


Annett 

A future version of IDB will allow some background garbage collection 
to be configured. However, in the meantime, you could modify the 
RmiJdbc code so that it calls java.lang.system.gc() periodically, say 
by checking the amount of available memory within 
RJStatementServer.executeQuery() (and similar) calls.

Hello,

I have some problems with the InstantDB.
I use Instant-DB 3.24beta3 and the RMI-driver (RmiJdbc 2.0) - both run.
I have a small program to test the database-login. 
I notice that the CPU- and Memory-use by the RMIJDBC becomes extremly high.
The first entry "java exe" (PID 322) is RMIJDBC - see screenshot please:

  <<tm-memory.gif>>  <<tm-process.gif>>                 

The RMIJDBC shows also an error:

 <<RMIError.txt>> 

The result is that my application which runs with instant-DB notifies:
"OutOfMemoryException" and stops!

Have you any ideas for that problem?
I think it's caused by the RMIJDBC?
Have you already heard anything similar?


Thanks 

Regards
Annett
