Stopping the SAP System

It may be necessary to stop an SAP system for a variety of reasons, for example,

restarting after permanently changing profile parameters, before installing kernel

patches, or allowing hardware upgrades to be carried out.

Before you stop the system, you should check the status of the system.

 This involves, among other things:

. Active Users:

  Check which users are logged on using the User List (SM04).

. Background Processing :

  Check which jobs are active using the Job Overview (SM37). If jobs are

  terminated by the system stop, these jobs must be rescheduled. Jobs that are

  scheduled for the time when the system is stopped run automatically once

  the system restarts.

. Batch Input:

The transaction Batch Input: Session Overview (SM35) displays running

batch input jobs.

. Update:

Use the Update Overview (SM13) to check whether update processes are

terminated by the system stop. These update records are rolled back during

the stop, and these are set to the status .init.. These records are then updated

again during the restart.

Before you stop your system, you should inform users using a system message

(SM02).

Enter the command stopsap to stop an instance.
