***************************************************************************
The WebLogic Server encountered a critical failure
Reason: PermGen space
***************************************************************************
Exception in thread "main"
Solution:
Weblogic is running with Java JDK. For JDK we need to pass this parameter -XX:MaxPermSize in startup argument.
This parameter needs to be setup along with the heap argument.
Go to setDomainEnv.sh file, edit the memory parameter for each server as:
if [ "${SERVER_NAME}" = "AdminServer" ] ; then
USER_MEM_ARGS="-Xms2048m -Xmx2048m -XX:MaxPermSize=1024m"
fi
if [ "${SERVER_NAME}" = "soa_server1" ] ; then
USER_MEM_ARGS="-Xms2048m -Xmx2048m -XX:MaxPermSize=1024m"
fi
