How to change SYSMAN Password in OEM 12c

1. Stop all OMS instances running emctl stop oms.

$OMS_Home/bin/emctl stop oms

Execute the same command on all the OMS machines including the primary OMS machine. Do not include '-all' as the Admin Server needs to be up during this operation.

2. Modify the SYSMAN password:

$OMS_Home/bin/emctl config oms -change_repos_pwd

Provide Repository User's Current Password and Repository User's New Password in command prompt

3. Stop the Admin server on the primary OMS machine and re-start all the OMS:

$OMS_Home/bin/emctl stop oms –all

4. Restart all the Management Services:

$OMS_Home/bin/emctl start oms
