Procedure documentation Activating the Backup Domain Controller  Locate the document in its SAP Library structure


If your domain controller failed and you have to make changes to the TMS configuration, you can activate the backup controller.


To activate the backup domain controller:

  1. Log on to the SAP System functioning as the backup domain controller.
  2. Enter Transaction STMS.
  3. Choose Overview ® Systems. The system overview appears.
  4. Choose Extras ® Activate backup controller.
  5. Confirm the prompt.


The backup domain controller is activated as the transport domain controller. The configuration change is distributed to all SAP Systems in the transport domain. The status bar indicates SAP System in which the configuration is being adjusted.


When you have activated the backup domain controller, the "old" domain controller is automatically made the "new" backup controller, if it can be accessed.


As long as the information that the domain controller has changed cannot be distributed to all the SAP Systems of the transport domain, the system overview of the new controller shows that the backup controller activation is still incomplete.

You can only change the transport domain configuration if the backup controller is completely activated.
