Start of User Roll-Over to Bridge Subsystem

This section deals with the transition of the users to the bridge subsystem.

Start of User Roll-Over to Bridge Subsystem

The transition of the users to the bridge subsystem in phase MAIN_BRITRANS/REQ_USER_ROLLOVER_PREP starts and rolls all users and work processes over to the bridge subsystem.

If the system is configured for a connection to the database using the Secure User Store (hdbuserstore), make sure that all application servers instances have access to the shared hdbuserstore.

If the hdbuserstore is stored on a local file system, perform one of the following options:

  • Option 1:

    On the remote ABAP hosts, manually create hdbuserstore for the shadow system connection using the following command:

    hdbuserstore SET UPGSHDKEY <ENV> <USERNAME>SHD <PASSWORD> <ENV>
  • Option 2:

    Switch your database connection to the ABAP Secure Store (SSFS).
