(Doc ID 1365930.1)
Last updated on JANUARY 28, 2025
Applies to:
Enterprise Manager Base Platform - Version 12.1.0.1.0 and laterInformation in this document applies to any platform.
Goal
This article provides steps for modifying the password of SYSMAN and other Enterprise Manager (EM) Cloud Control users in the OMS configuration and the Repository database in a Cloud Control system.
Simply changing the password in the repository database SYSMAN account is not sufficient as the password is also stored in the WebLogic Server (WLS) credential store. The OMS uses the SYSMAN account to log in to the repository database and if there is a mismatch in the password in the database SYSMAN account and in the OMS configuration, the OMS cannot start and function properly.
For steps to follow in the earlier Enterprise Manager versions, refer to:
<Note 270516.1>: How to Change the Password of SYSMAN User in 10g and 11g Grid Control
Starting with EM 12c, directly modifying the password for SYSMAN or any other repository user at the Repository Database is not recommended.
Hence, ensure that the passwords are changed only using one of the methods listed below.
Due to the importance of the SYSMAN schema to the proper functioning of EM 12c Cloud Control, users who wish to change the SYSMAN password with the procedure described here are advised to back up the OMS instance(s) and repository prior to beginning the password change procedure. This reference shows how to back up the EM 12c components (and restore, should it be necessary):
