Scenario

This section describes how to periodically change the password of the OMS database administrator to improve the system O&M security.

Procedure

  1. Log in to the active management node.

    The password of user ommdba cannot be changed on the standby management node. Otherwise, the cluster may not work properly. Change the password on the active management node only.

    sudo su - omm

  3. Run the following command to switch the directory:

    cd $OMS_RUN_PATH/tools

  4. Run the following command to change the password of user ommdba:

    mod_db_passwd ommdba

  5. Enter the old password of user ommdba and enter a new password twice.

    The password complexity requirements are as follows:

    • The password contains 16 to 32 characters.
    • The password must contain at least three types of the following: uppercase letters, lowercase letters, digits, and special characters ('~!@#$%^&*()-_=+\|[{}];:'",<.>/?).
    • The password cannot be the username or the reverse username.
    • The password cannot be the same as the last 20 historical passwords.

    If the following information is displayed, the password is changed successfully.

    Congratulations, update [ommdba] password successfully.
