java.lang.OutOfMemoryError: allocLargeObjectOrArray: [B, size 16400.

Oracle Identity Management (OIM) configured with LDAP for fusion applications 11.1.4, throws error after 2 days of operations.

The error was as follows:

The error was due to setDomainEnv.sh which is called by startWeblogic.sh during Managed server start.


So search the setDomainEnv.sh which is used by which files.

[oracle@fusionapp bin]$ grep -r "setDomainEnv.sh" .
./secureWebLogic.sh:. ${DOMAIN_HOME}/bin/setDomainEnv.sh $*
./nodemanager/wlscontrol.sh:        # setDomainEnv.sh script exists, so call it to set up the default
./nodemanager/wlscontrol.sh:        # No setDomainEnv.sh script available, so set up default environment
./nodemanager/wlscontrol.sh:SetDomainEnvScript=$DomainDir/bin/setDomainEnv.sh
./stopWebLogic.sh:. ${DOMAIN_HOME}/bin/setDomainEnv.sh ${exitFlag}
./startWebLogic.sh:. ${DOMAIN_HOME}/bin/setDomainEnv.sh $*



Fix:

Edit the lines in setDomainEnv.sh from DOMAIN_HOME/bin (IDMDomain/aserver/IDMDomain/bin)

Save and exit.


Bounce the Managed server. Look for the memory usage in weblogic control or through OS commands.
