You can use this procedure to stop and restart the J2EE Engine in case of the J2EE Engine installed as an add-in in a SAP Web AS ABAP System.

Note Note

The J2EE Engine gets automatically started with the ABAP System, but you can stop and restart the J2EE Engine. If you don't restart the J2EE Engine it will be launched again with the next restart of the ABAP System.

End of the note.

Procedure

  1. In the ABAP System start the ICM Monitor (transaction SMICM or by choosing   Administration   System Management   Monitor   System Monitoring   Internet Communication Manager  ).

  2. On the initial screen of the ICM monitor (Transaction SMICM), choose   Administration   J2EE Server  .

  3. Choose one of the following functions:

    • Sending a Soft Shutdown (With or Without a Restart)

    The (ABAP) dispatcher of the SAP Web Application Server sets the restart flag for the J2EE Engine and sends the SOFTSHUTDOWN message to the J2EE Engine. The dispatcher does not actively close the connection, the J2EE Engine must close itself instead. If the application server is restarted, the J2EE Engine is restarted by the dispatcher.

    • Sending a Hard Shutdown (With or Without a Restart)

    The (ABAP) dispatcher of the SAP Web Application Server sets the restart flag for the J2EE Engine and sends the HARDTSHUTDOWN message to the J2EE Engine. The dispatcher does not actively close the connection, the J2EE Engine must close itself instead. If the application server is restarted, the J2EE Engine is restarted by the (ABAP) dispatcher.

    • Ending the Process (With or Without a Restart)

    The SAP Web Application Server's dispatcher sets the restart flag for the J2EE Engine and sends a signal to the process (shell or Java process). If the application server is restarted, the J2EE Engine is restarted by the dispatcher.

    • Restart Yes/No

    This sets the J2EE Engine's restart flag.
