Information in this document applies to any platform.

Goal

This documents explains how to re-configure the 11g OMS when the listener port of the database holding the Grid Control Repository is changed.

Note: This document assumes that the port for the Listener has already been modified at the Repository Database machine. If needed, steps suggested in Document 359277.1: Changing Default Listener Port Number
can be followed.

For instructions on how to achieve this for a 10g Grid Control setup, refer to
Note 369997.1: How to Re-configure the OMS After Port Change for the Listener Servicing the Grid Control Repository Database.

Solution

Re-configuring the Oracle Management Service (OMS) 

1. Stop the OMS

cd <OMS_HOME>/bin
emctl stop oms

Note: Do not use 'emctl stop oms -all', the Admin server needs to be 'Up' for the changes to be recorded.

2. Modify the connect descriptor for the Repository Database in the Weblogic Credential Store using:

cd <OMS_HOME>/bin
emctl config oms –store_repos_details -repos_conndesc <connect descriptor> -repos_user sysman

Note: The value of the connect descriptor input string needs to be enclosed in quotes twice i.e "'connect_descriptor'" or '"connect_descriptor"'

OR

emctl config oms -store_repos_details -repos_host <host> -repos_port <port> -repos_sid <sid> -repos_user <username> [-repos_pwd <pwd>] [-no_check_db]

Examples:

emctl config oms –store_repos_details -repos_conndesc "'(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=repomachine.domain)(PORT=1522))(@ CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=rep11g)))'" -repos_user sysman

OR

emctl config oms -store_repos_details -repos_host repomachine.domain -repos_port 1522 -repos_sid rep11g -repos_user sysman

3. Start the OMS(s) using the command

cd <OMS_HOME>/bin
emctl start oms.

Re-configuring the 'OMS and Repository' Target

The 'OMS and Repository' target is used for monitoring the overall health of the Grid Control environment. You also need to change the configuration of this target in order to reflect the new port number:

1. Open the Grid Console in a browser
2. Navigate to Targets -> All targets -> Search -> 'OMS and Repository' -> Go
3. Click Configure
4. Enter the new port number in the 'Repository port' field
5. Click OK

Or execute: 

cd <OMS_HOME>/bin
emctl config emrep -conn_desc "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=<host>)(PORT=<new_port>)))(CONNECT_DATA=(SID=<sid>)))"

For example:

emctl config emrep -conn_desc "(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=repomachine.domain)(PORT=1522)))(CONNECT_DATA=(SID=rep11g)))"

Re-configuring the Listener Target

The Database holding the Repository of Grid Control is just like any other Database target as far as the Agent is concerned. We need to inform the Agent of the port change in order to allow it to monitor the Database. You need to perform the following in order to do this:

1. Open the Grid Console in a browser.
2. Navigate to Targets -> Databases
3. Select the radio button next to the Repository Database target and click configure.
4. Enter the new listener port in the 'Port' field and press the 'Test Connection' button. This should be successful.
5. Click Next till the end of the Wizard
6. You can verify that the changes made it to the Agent by checking the <AGENT_HOME>/sysman/emd/targets.xml . This should contain the new listener port for the repository database.

Note: You also need to do this for any other database that may have been impacted by the port change.
