Enhanced Event Logging for SNA Server Event 9, 12
ID: Q181121
|
The information in this article applies to:
-
Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2
SUMMARY
To improve the ability to troubleshoot SNA Server Event 9 (subcode 1117)
and Event 12 errors, these events have been enhanced to include the
following additional information:
- Client Domain
- Client User (name)
- LU name (3270 LU)
- FMI Sense Code
When SNA Server logs an Event 9 (subcode 1117), the SNA Server has detected
an SNA protocol violation by the 3270 emulation product being used. The
Event 9 indicates a non-fatal protocol violation which would not cause a
user to lose their 3270 session. If SNA Server detects a nonrecoverable
3270 protocol violation by the 3270 emulation product, SNA Server logs an
Event 12.
Using SNA Server 3.0 (including 3.0 SP1 and SP2), it's not possible to
determine which client workstation caused these problems to occur, making
troubleshooting more difficult. These events have been enhanced so that
the specific client user can be tracked down.
To debug the exact cause of these events, SNA Server 3270 message tracing
is needed on either the server or the client computer.
MORE INFORMATION
SNA Server 4.0 already includes these enhancements to SNA Server Event 9
and 12. These changes have been retrofitted to SNA Server 3.0 Service Pack
3 (SP3) in order to improve diagnostic capability for the 3.0 product.
Here is the event message text for these enhanced events:
