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 ??

    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.
