Filed under: Uncategorized — mani @ 11:03 pm

Oracle Agent stopped working all of sudden.

Agent stop populating to grid. Stopped, Did clearstate, restarted agent. Nothing worked.

Tried following steps too, but no help.

1 stop the agent
2 delete agntstmp.txt and lastupld.xml (under sysman/emd)
3 Delete all the files under upload and collection directories
4 start the agent
Here it is a real solution.

Go to Grid Control,
Click on Setup
Choose Agents
Choose the Problematic Agent
Click on Unlock.
Resynchronize the agent.
