Q148312: No RTM Data Generated If 3270 Session Uses Exception Response

Article: Q148312
Product(s): Microsoft SNA Server
Version(s): WINDOWS:2.11,2.11 SP1
Operating System(s): 
Keyword(s): kbnetwork

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft SNA Server, versions 2.11, 2.11 SP1, on platform(s):
   - the operating system: Microsoft Windows NT 
-------------------------------------------------------------------------------


SYMPTOMS
========

The SNA Server 2.11 3270 Windows and Windows NT applets support the generation
of response time monitor (RTM) performance data, which SNA Server then provides
to NetView. However, if host subsystem (such as CICS, IMS, TSO) is configured to
use exception response protocol instead of definite response protocol, the 3270
applet does not report performance data to the SNA Server. This causes the SNA
Server to fail reporting data to NetView.

NOTE: For response time monitor (RTM) data to be reported by SNA Server to
NetView, a 3270 emulator must supply performance data on STATUS-Acknowledge
messages to SNA Server as described in the SNA Server Emulator Interface
Specification (EIS), section 3.3.15 and 4.8. SNA Server has supported the
response time monitor interface since version 2.0. The 3270 applet did not
support the interface until version 2.11.

This problem also occurs on Attachmate Extra! version 4.2. Earlier versions of
Extra! do not support the SNA Server response time monitor reporting feature.
Contact Attachmate Technical Support for availability of an Extra! update.


CAUSE
=====

If you use the exception response protocol on the 3270 applet session,
Status-Ack messages are not sent to SNA Server. No response time monitor data
has been reported to the server, even if the response time monitor feature has
been enabled.

RESOLUTION
==========

To work around this problem, change the host subsystem configuration so that the
3270 applet sessions use definite response.

To correct this problem, apply the fix mentioned below.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server 2.11 and 2.11 Service
pack 1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S.
Service Pack. For information on obtaining the service pack, query on the
