FIX: SNA Manager does not display the correct remote APPC LU session status if you update the SNA Manager MMC snap-in after APPC sessions are re-established in Host Integration Server (885429)


The information in this article applies to:

  • Microsoft Host Integration Server 2000
  • Microsoft Host Integration Server 2000 SP1
  • Microsoft Host Integration Server 2004

SYMPTOMS

In Microsoft Host Integration Server 2000 and Host Integration Server 2004, SNA Manager does not display the correct Advanced Program-to-Program Communications (APPC) session status when you view a remote APPC logical unit (LU). This problem occurs if the SNA Manager MMC snap-in is updated after APPC sessions are reestablished.

When the problem occurs, it seems that no active sessions exist over the remote APPC LU that is being viewed in SNA Manager. If you change the focus in SNA Manager to view the local APPC LU that is partnered with the remote APPC LU, SNA Manager shows that active sessions exist over the remote APPC LU.

CAUSE

This problem occurs because the Host Integration Server management components do not correctly update the remote APPC LU status after the SNA Manager MMC snap-in is update and the update occurs after APPC sessions are reestablished.

This problem was corrected in Microsoft Host Integration Server 2000 Service Pack 2.

MORE INFORMATION

Steps to reproduce the problem

  1. Open the SNA Manager MMC snap-in.
  2. Expand the Host Integration Server subdomain tree, and choose a configured remote APPC LU.
  3. Start an APPC application that will establish an APPC session by using the remote APPC LU that you chose in step 2. Do this so the correct status appears for an active APPC session.
  4. Stop the SNA Server service that the chosen remote APPC LU is using to communicate with the IBM host system.
  5. After the SNA Server service has successfully stopped, restart the SNA Server service.
  6. Start the APPC application again to establish an APPC session by using the same remote APPC LU.
  7. Press F5 to update the SNA Manager MMC snap-in.

    The active APPC sessions that previously appeared when you viewed the remote APPC LU no longer appear even though they are still active.

    If you change the focus in SNA Manager to the local APPC LU that the APPC sessions are also using, the correct status of the APPC sessions will appear.
