SYMPTOMS
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.



STATUS


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:

  =============================== Event ID: 9 Source:  SNA Server Description: A protocol error occurred due to a message sent by a 3270 emulator or link service

EXPLANATION A protocol error occurred due to a message sent by a 3270 emulator or  link service.

SUBCODE INFORMATION X'1117' A 3270 emulator used by the following user caused an error, though the user's 3270 session was not interrupted:

Client Domain: Client User: LU name: FMI Sense Code:

===============================

Event ID: 12 Source:  SNA Server Description: A 3270 Session was lost due to a protocol error in the 3270 emulator.

A user has lost their 3270 session due to a non-recoverable protocol error caused by the 3270 emulator being used. The following user encountered this error.

Client Domain: Client User: LU name: FMI Sense Code:

ACTION To troubleshoot this problem, capture matching SNA client 3270 message traces from this user's machine and SNA Server DLC and 3270 message traces on the server, and provide them to Microsoft product support.
