EnterpriseManager 10g errors (ORA-12541, TNS-12541)

  Hi all,

I've installed a Database 10.2.0.4 on a Failsafe 3.4.1 cluster with two nodes.

My EnterpriseManager 10g works only on one node correctly. If the cluster switched to the other node, I get same errors:

ORA-12541: TNS:no listener (DBD ERROR: OCIServerAttach)
TNS-12541: TNS:no listener

If I connect the database with EnterpriseManager 9, I can administrate the database on each node.

On both nodes I've the same TNSNAMES.ORA, LISTENER.ORA.

Please, can you help me?

Howdy, Stranger!
