If you create a new database, listener, etc. on a machine that has an existing Grid Control Agent on it, you may need to tell the agent to “rescan” the system to pick up the new database (to have the DB show up in OEM).

Set your agent home

AGENT_HOME=/opt/app/oracle/agent10g

Make sure $AGENT_HOME/bin is in your PATH
Run the agentca with the reconfigure option. (you may need to specify a –c for RACs)

vexbert<11> agentca -h
Usage: agentca -d/-f [-nctis]
        -d  option for rediscovery.
        -f  option for reconfigure.
        -n  to specify the CLUSTER_NAME.
        -c  specify the list of cluster nodes separated by commas
        -t  don't start the agent after rediscover or reconfigure.
        -i  oraInst.loc location on Unix/Linux Platforms only.
        -s secure the Agent during RAC/Cluster Agent reconfiguration
         (Don't use this option in upgraded home).

vexbert<11> agentca –f

Note: you may need to clean up duplicates in your OEM after running this on an existing system.
