Fred, The discovery process is actually talking to the Oracle agent running on the box. When the agent starts up, it reads the tnsnames.ora file and the oratab file. Also look at the snmp_ro.ora. This will tell you all of the databases (and listeners) that the Oracle agent has discovered. All of this info is passed to EM when you discover a node. Good Luck!

I started the intelligent agent on the other nodes that I will access. Then I do a "discover nodes". Can anyone explain the results of node discovery? The node I discover has 6 databases on it, however the node discovery comes back with 10 ....... why is this? What did it "read" to "discover" these things it thinks are databases???
