What do you mean by NODES? Are you talking about Rac Instances?
Or individual databases?

Are you trying to discover a local or remote node?

Are you receiving any error message(s)? Did you look at the log files in %ORACLE_HOME%\sysman\log directory?

You could try to stop the listener, agent & OMS then delete the snmp_rw.ora & snmp_ro.ora files in %ORACLE_HOME%\network\admin directory . Once the files have been deleted, restart the components and try to discover the node again.

You may want to try to enter a fully qualified hostname in your listener.ora file. You may also need to enter this into your snmp_rw.ora file.

If this doesn't seem to solve your problem, you can try to add an entry into your listener.ora file for the database itself.
