Troubleshooting
Problem
Profile creation failed, the following error messages appear in collect_metadata.log: JVMSHRC287E Persistent cache cannot be located on a networked file system. Either select "nonpersistent" or a different cacheDir. JVMJ9VM015W Initialization error for library j9shr26(11): JVMJ9VM009E J9VMDllMain failed Could not create the Java virtual machine.
Symptom
The profile creation failed with the following error messages showing in /[WAS_Install_root]/logs/manageprofiles/[profile_name]/collect_metadata.log:
JVMSHRC287E Persistent cache cannot be located on a networked file system. Either select "nonpersistent" or a different cacheDir.
JVMJ9VM015W Initialization error for library j9shr26(11): JVMJ9VM009E J9VMDllMain failed
Could not create the Java virtual machine.
Cause
When the wsadmin listener was getting initialized and the 'collect metadata task' was being invoked via manageprofiles script, "-Xshareclasses" option was specified as a performance improvement for WebSphere Application Server version 8.5. However, since the default cache location which is /tmp/javasharedresources is on a network file system (NFS), the JVM is having problems obtaining a lock in file system, therefore, profile creation fails with error.
Resolving The Problem
In order to work around this issue, the following files need to be modified to avoid caching java class objects under /tmp/javasharedresources directory.
/[WAS_Install_root]/bin/manageprofiles.sh
/[WAS_Install_root]/bin/launchWsadminListener.sh
/[WAS_Install_root]/profileTemplates/cell/dmgr/actions/scripts/collectNodeMetadata.sh
/[WAS_Install_root]/profileTemplates/cell/default/actions/scripts/collectNodeMetadata.sh
/[WAS_Install_root]/profileTemplates/default/actions/scripts/collectNodeMetadata.sh
/[WAS_Install_root]/profileTemplates/managed/actions/scripts/collectNodeMetadata.sh
/[WAS_Install_root]/profileTemplates/management/actions/scripts/collectNodeMetadata.sh
/[WAS_Install_root]/profileTemplates/secureproxy/actions/scripts/collectNodeMetadata.sh
In each of the above files, search for "-Xshareclasses" entry for your current platform "linux", and then change it to "-Xshareclasses:none".
"-Xshareclasses:nonpersistent" should also work as well.
