SNA Server 4.0 Always Checks for Remote APPC LU Security (193816)
The information in this article applies to:
- Microsoft SNA Server 4.0 SP1
- Microsoft SNA Server 4.0
This article was previously published under Q193816 SYMPTOMS
When SNA Server 4.0 receives an allocation request from an APPC or CPIC
application, SNA Server always verifies that the user has authority to
access the Remote APPC LU requested, even if APPC security is not enabled
within SNA Server Manager or the Microsoft Management Console (MMC). This
may reduce the performance of an APPC or CPIC application, including COM
Transaction Integrator (COMTI).
Under heavy APPC or CPIC application testing, this problem can cause the
server-side SnaBase service to use 15 percent to 20 percent of the CPU (as
measured by Windows NT Performance Monitor) even while no new SNA Server
clients are connecting to the server.
CAUSE
SNA Server is incorrectly checking user access even when Remote APPC LU
security is not enabled within the SNA Server configuration file.
RESOLUTION
Microsoft has confirmed this to be a problem in SNA Server versions 4.0 and
4.0 Service Pack 1. This problem was corrected in the latest SNA Server
version 4.0 U.S. Service Pack. For information on obtaining this Service Pack,
