SNA Manager Improvements When Many 3270 LUs Are Configured

• Microsoft SNA Server, version 3.0
  on the following platforms: NT

SYMPTOMS

SNA Server Manager performance is slow when there are a large number of 3270 LUs configured. Also, if the connection or active users window is not being viewed, the client session counts may be incorrect.

CAUSE

SNA Server Manager was recounting active sessions when a 3270 LU was opened or closed. Also, if 3270 LUs aren't viewed in Manager, status information wasn't being received for these LUs, causing client session counting to be incorrect.

RESOLUTION

An update to SNA Server 3.0 is available to correct this problem. To resolve this problem, obtain the hotfix mentioned below.

The session counting is now done on the server in a thread which activates every 15 seconds. It sends updated counts to Manager if counts have changed. This means that session count updates in Manager may be delayed by as much as 15 seconds.

STATUS

Microsoft has confirmed this to be a problem in SNA Server version 3.0. This problem was corrected in the latest Microsoft SNA Server 3.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
