Why does Weblogic cache so much memory and how can is see how much memory has been cached ?

Why does BEA's WebLogic cache so much o/s memory and how can i see how much is being cached and can i released more back to the o/s. We are running a third party application called 'Manugistics' using BEA Weblogic running on top of an Oracle Database. After running a big batch job through Weblogic the o/s physical memory is being almost totally used and nothing is given back after the process has ended - is this a memory leak or is this how weblogics work ??
thanks

Hello,

Can you describe your server's environment. Memory, Server OS, etc.

Hi RLI,

We are running on unix IBM AIX 5.2 - there is 8GB RAM available - with the Oracle 9.2 database and Weblogic started up only 500M is used. After running a batch through WebLogic - approx 7GB is taken from the o/s and this is kept and not released back to the o/s by WebLogic once the batch has stopped and completed successfully - thus other programs and database queries and even processes fail with no memory available. Once Weblogic has been restarted/rebooted the memory is released back to the o/s and everything else works fine again. If we continuosly bounce Weblogic we won't get any problems but this is not a viable solution.

cheers
