I am adding nodes to the OEM server and I'm having trouble discovering the db's. The nodes refresh fine. TNS and LISTENER seem ok. Anyone have the same problem.

Thx

Despite the fact that Oracle 9i databases are self-registering in the listener, you must still define entries for 9i databases in the listener.ora for agentctl to discover those databases.

Agentctl 'discovery' is not done through querying the listener - it is done by parsing the listener.ora file.

Therefore, make sure your listener.ora in $ORACLE_HOME/network/admin looks something like:

# LISTENER.ORA Network Configuration File: # /usr/app/oracle/product/9.2.0/network/admin/listener.or a # Generated by Oracle configuration tools.

LISTENER = (DESCRIPTION_LIST = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST = node.company.com)(PORT = 1521)) ) ) )

SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = sid.company.com) (ORACLE_HOME = /usr/app/oracle/product/9.2.0) (SID_NAME = sid) ) )

Hi, For autodiscover the database....oracle intelligent agent should be runing on database server................and entry in TNS and LISTENER should be ok...

to start oracle agent ........$agentctl start

After that you will able to discover the DB from OEM.
