Remove monitored DB from EM

[did02]

Hi all,

Has anyone experienced to remove a monitored database from EM ? What are the main steps (Oracle 10g on W2k3) ?
- stop agent,
- remove agent
- remove $ORACLE_HOME\hostname_sid directory
- remove oc4j instance
- update $ORACLE_HOME\install\portlist.ini

what else (config file to modify) ?

Thanks for your advice.

I found the answer into Oracle Doc :

Stop Database Control Service Before Deinstalling.
If you want to deinstall Oracle software or delete Database Control configuration, then Oracle recommends that you first stop the Database Control service (named OracleDBControlSID). This assures complete deconfiguration of Database Control.
For Real Application Clusters databases, the Database Control service should be stopped on each node in the cluster.

Not doing so will not fail the deinstallation, but you might encounter Enterprise Manager configuration directories that are not cleaned up after deinstallation. This is because some processes are holding handlers to Enterprise Manager configuration files if processes are not shut down completely.

If you encounter errors when deconfiguring Enterprise Manager, then you can manually delete the following Enterprise Manager configuration directories:

ORACLE_HOME\HOSTNAME_SID

ORACLE_HOME\oc4j\j2ee\OC4J_DBConsole_HOSTNAME_SID

The same problem may occur when running Enterprise Manager Configuration Assistant in standalone mode to remove Enterprise Manager configuration without removing the database (emca.bat -x). The same solution should be applied if this problem is encountered.
