How To Change The Sysman Password for Grid Control

July 30, 2012 admin OEM, Oracle

(Note:270516.1)
You need to change the sysman user password for Grid Control. Sysman is the owner of the EM 10g Repository schema so the password change must be made in the Database as well as in the EM configuration files. The instructions are listed below.

To change the Sysman password:
1. Stop the OMS instances that are associated with the repository
a. opmnctl stopall

2. Change the sysman password in the database:
a. Logon to sqlplus as a dba user
b. Issue the command: alter user sysman identified by newpassword;
c. Exit Sqlplus

3. On each management server host, cd to the OMS $ORACLE_HOME/sysman/config directory
a. backup the emoms.properties file
b. edit the emoms.properties file and modify the parameters;
eml.mntr.emdRepPwd=new_password
oracle.sysman.eml.mntr.emdRepPwdEncrypted=FALSE

NOTE: When you restart the OMS, the FALSE setting will change to TRUE and the password will become encrypted in the file

4. Still on Management Repository host, cd to the AGENT_HOME/bin and stop the agent:
./emctl stop agent
5. Next, cd to the AGENT_HOME/sysman/emd directory
a. Edit the targets.xml file and modify the oracle_emrep target definition with the following in bold:






..
..
b. Save the file. The TRUE value will change to FALSE and the newpassword will become encrypted when you restart the Agent.

6. Issue the command (from the Agent O_H/bin):
./emctl start agent

7. Restart each of the OMS’s
emctl start oms

8.Start the OMS instances that are associated with the repository
opmnctl startall
