Viewing the Status of Active APPC, LU6.2, and 5250 Sessions

MORE INFORMATION

SNA Server 2.x

The SNA Server Admin program allows the administrator to see which users are using APPC, 5250, LU6.2 sessions through SNA Server, and allows the administrator to deactivate or reset the sessions.

An independent LU6.2 APPC LU can support multiple concurrent sessions, but the main SNA Server Admin screen does not display them all because it was not designed to support multiple concurrent sessions. Instead, the Local APPC LU indicates the number of active sessions in the Status column within the main Server and Connections window.

To view the detailed status of APPC LU sessions and to disconnect them, follow these steps in SNA Server Admin:

1. To find the Local APPC LU within SNA Server Admin, go to the Servers and Connections window in SNA Server Admin and select the SNA Server you are interested in.
   
   This causes the Local APPC LUs to appear on the right side of the window.
   
   NOTE: The Status column indicates the number of LU6.2 sessions currently used over this Local APPC LU (if no sessions are used, the Status is Inactive).
2. Select the Local APPC LU and from the Services menu choose Properties.
   
   This brings up the APPC LU Properties dialog.
3. Choose the Status button.
   
   This brings up the APPC LU Status dialog box, which shows all Remote APPC LU/Mode partnerships that this Local LU is partnered with. For example, if this Local APPC LU is partnered with multiple Remote APPC LUs associated with multiple AS/400 computers, the window displays the following:

            Server Name:     SERVER
            Local LU Alias:  LOCAL
   
         Partner LU   Mode       Connection    Sessions     Limit
   
         AS400A       QPCSUPP    TOKEN1         10           64
         AS400A       SNASVCMG   TOKEN1          0            2
         AS400B       QPCSUPP    TOKEN2          4           64
         AS400B       SNASVCMG   TOKEN2          0            2
   						

   In this example, the Local APPC LU named LOCAL has 10 active sessions to AS400A, and four active sessions to AS400B over the QPCSUPP mode (the default mode name used to communicate with AS/400 systems). The session limit is also shown, which was negotiated during initial LU6.2 session activation with the remote system.
   
   You can ignore the SNASVCMG mode, defined by IBM SNA LU6.2 architecture; this mode name is not used by APPC/CPIC applications.
4. Select the Partner LU/Mode line and choose the Zoom button.
   
   This displays detailed status information on the active sessions users have to this Partner APPC LU. Here is some sample output that appears when choosing the AS400B/QPCSUPP mode in the previous example:

               Local LU Alias:   LOCAL
               Partner LU Alias: AS400B
   
         User                Computer       Executable    Time Started
   
         DOMAIN\ANDYB        ANDY           SNASRV        8:15:00am Jul 26
         DOMAIN\STUARTF      STUART         SNASRV        9:15:16am Jul 26
         DOMAIN\JOHND        JOHN           SNASRV        11:18:10am Jul 26
         DOMAIN\STEVEOS      STEVE          SNASRV        3:48:45pm Jul 25
   						

5. To deactivate a specific APPC session, select the desired user entry and choose on the Deactivate button.
   
   This causes the APPC LU session to be disconnected and frees up the LU for another user. Users whose sessions you deactivate can reopen their APPC sessions again as long as the LU/LU/mode pair is not already at the negotiated session limit.

SNA Server 3.0 and 4.0

The SNA Server Manager program allows the administrator to see which users are using APPC, 5250, LU6.2 sessions through SNA Server, and allows the administrator to deactivate or reset the sessions.

To view the detailed status of APPC LU sessions and to disconnect them, follow these steps in SNA Server Manager:

1. Select the SNA Server you are interested in from within SNA Server Manager.
2. Open either the Local APPC LUs folder or the Remote APPC LUs folder to see a list of the Local or Remote APPC LUs that are defined for that SNA Server.
3. Choose one of the listed Local APPC LUs in the Local APPC LUs folder or one of the Remote APPC LUs in the Remote APPC LUs folder.
   
   This causes the Active sessions for the selected APPC LU to be displayed on the right side of the Manager window. For example, if a Local APPC LU called LOCAL is selected in the Local APPC LUs folder, the window display might look as follows:

           Active APPC sessions on local LU 'LOCAL' (3)
   
           Partner LU   Mode       User Name         Client
   
           AS400A       QPCSUPP    NTDOMAIN\user1    CLIENT1
           AS400A       QPCSUPP    NTDOMAIN\user2    CLIENT2
           AS400B       QPCSUPP    NTDOMAIN\user3    CLIENT3
   						

   In this example, the Local APPC LU named LOCAL has 2 active sessions to AS400A, and one active session to AS400B over the QPCSUPP mode (the default mode name used to communicate with AS/400 systems).
   
   If a Remote APPC LU was selected, the resulting display would show the same information as was listed above, but it would only be for active sessions using that Remote APPC LU.
4. To deactivate a specific APPC session, right-click on the desired entry and select 'Stop'.
