Configuring the Backup Domain ControllerLocate this document in the navigation structure

Prerequisites

In your transport domain, the SAP System which is configured as the domain controller is of special signifance. If this SAP System fails, you cannot make changes to the TMS configuration during this time. If your transport domain contains more than three SAP Systems, we therefore recommend that you configure a backup domain controller. If your domain controller fails, the backup controller can assume the function of the domain controller.

Caution

The SAP System that you want to use as the backup controller must have the same release version as the transport domain controller. Otherwise, configuration information may be lost when changing the domain controller.

Procedure

To configure a backup domain controller:

  1. Log on to the SAP system that functions as the transport domain controller.
  2. Call transaction STMS.
  3. Choose Start of the navigation path Overview Next navigation step Systems End of the navigation path. The system overview appears.
  4. Position the cursor on the domain controller.
  5. Choose Start of the navigation path SAP System Next navigation step Change End of the navigation path. The screen Change TMS Configuration: System <SID> appears.
  6. In the field Backup, enter the SAP System to be used as the backup controller of your transport domain.
  7. Save your entries and distribute the configuration change.
