Monitoring the Reconnection of Work Processes

This section deals with monitoring the reconnection of the work processes.

Context

In phase MAIN_BRITRANS/BRIDGE_RECONNECT, the Application Server ABAP (AS ABAP) work processes are reconnected from the original database schema to the database schema of the bridge subsystem. However, the work processes cannot be reconnected until they have completed the current unit of work.

To identify the work processes that have completed the reconnection, do the following:

Procedure

  1. Call transaction SM66 in your SAP system.
  2. Choose the icon Change Layout.
  3. From the Column Set box, select Database Reconnect Status and drag it to the Displayed Columns box.
  4. Choose Apply.

    As a result, the Database Reconnect Status column of each work process is displayed as an additional column in the work process overview.

    If the reconnection exceeds your planned update schedule, you can force it manually. However, this can cause the termination of long-running batch jobs that prevented the work processes from reconnecting.

    To force the reconnection, open the Process Control Center in the More menu item SUM Utilities (Extended UI). Select the row with the process name FORCE_RECONNECT and choose Start.
