Tips on how to debug RemoteOperationException.,

I used OEM / EM a lot earlier, and figured out how to overcome RemoteOperationException, below are some of the reasons., !

• Check agent status (Agent should be up and running - just give a restart if you doubt)
• Stop agent before any changes., and start after !
• Check the file/folder permissions (parent folder too)
• Check the file/folder ownership (owner.group) , make sure your are inline with your agent installation.
• Check privilege delegation settings
• For NMO not setuid-root issues
  
  • Run root.sh that is available in your agent
  • nmo,nmhs,nmb,nmosudo,nmgsshe,nmopdpx  - these files under agent should be owned by root user !
• Check if you are able to sudo with out any issues (sudo -u username ls)
  
  • ulimit - resource not available issues might crop up.,
  • Modify /etc/security/limits.conf if necessary (or ulimit -n 5000)
• Check for any disk space memory issues
• Change sysman/prov/agentpush/agentpush.properties
  • set enablePty=true and waitForPasswordPrompt=true

I am giving this out of experience, and this is NOT a official advice ! Try at your own risk. :D

All the best.,
