Caused By: java.lang.OutOfMemoryError: Metaspace

Solution :

1.Take the backup of setDomainEnv.sh file of our Oracle SOA 12c instance.

2. Add below parameters in setDomainEnv.sh.

In setDomainEnv.sh file, find the bellow snippet..

JAVA_OPTIONS="${JAVA_OPTIONS}"

export JAVA_OPTIONS

Change it as :

JAVA_OPTIONS="${JAVA_OPTIONS} -XX:MaxMetaspaceSize=1024m"

export JAVA_OPTIONS

[ try to put some higher size ie. 1024m]

3. Save, restart server after change and monitor server activity.

This way you can resolve the 'Metaspace' error in your Oracle Weblogic SOA 12c instance.
