Activating the Backup Domain Controller


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


To activate the backup domain controller, proceed as follows:

  1. Log on to the R/3 System which is being used as the backup domain controller.
  2. Call transaction STMS.
  3. Choose Overview ® Systems.
  4. This takes you to the system overview.

  5. Choose Extras ® Activate backup contr.
  6. Confirm the prompt.


The backup controller is activated as the domain controller. The configuration change is distributed to all R/3 Systems in the transport domain. The status bar indicates in which R/3 System the configuration is being adapted.

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

As long as the information that the domain controller has changed cannot be distributed to all the R/3 Systems of the transport domain, the system overview of the new controller displays that the activation of the backup controller is still incomplete.
