No RTM Data Generated If 3270 Session Uses Exception Response (148312)
The information in this article applies to:
- Microsoft SNA Server 2.11, when used with:
- the operating system: Microsoft Windows NT
- Microsoft SNA Server 2.11 SP1, when used with:
- the operating system: Microsoft Windows NT
This article was previously published under Q148312 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
