Integration

Done with weblogic domain setup a couple of days ago and observed the the heap reaches max. We get 90% heap alerts on a daily basis.

There are no applications running on the server. We have installed JVM diagnostics for OEM montoring & a war which monitors the status on the VIPs.

We have installed on a 2 node cluster running on RHEL 5.8 64 bit VM. Below is the weblogic & Jrockit version.


WebLogic Server 10.3.6.0
java version "1.6.0_31"


Heap Size : -Xms1536m -Xmx1536m

Gc strategy is default which is parallel Mark & Sweep.

-Xverbose:gcreport,memory,gcpause, -XverboseTimeStamp


Please advise why there is a high heap usage even though there are no business applications deployed and running.
