Modify any property on the High Availability property page – you must have the MANAGE MULTIPLEX system privilege, and the coordinator must be running. The SCC agent for the multiplex server for which the Properties page is open must also be running.

Task
  1. In the Perspective Resources view, select the resource, and select Resource > Administration Console.
  2. In the left pane, expand IQ Servers > Multiplex Management, and then select Multiplex Servers.
  3. Select the multiplex server in the right pane and either:
    • Click the drop-down arrow to the right of the name and select Properties, or,
    • From the Administration Console menu bar, select Resource > Properties.
  4. View or modify the server properties.
    • Configuration changes may take several minutes to complete.
    • When you are modifying properties, you need not click Apply before changing screens; however, doing so saves any changes.
    • If you do not have privileges to modify properties, SAP Control Center displays the properties view in read-only mode.
