BUG: Incorrect CONV_ID Traced for WinCPICSetEvent and WinCPICExtractEvent Verbs (316711)


The information in this article applies to:

  • Microsoft SNA Server 4.0
  • Microsoft SNA Server 4.0 SP1
  • Microsoft SNA Server 4.0 SP2
  • Microsoft SNA Server 4.0 SP3
  • Microsoft SNA Server 4.0 SP4
  • Microsoft Host Integration Server 2000
This article was previously published under Q316711

SYMPTOMS

Common Programming Interface for Communications (CPI-C) application programming interface (API) traces display an incorrect Conversation ID (CONV_ID) when tracing the following CPI-C verbs:
  • WinCPICSetEvent
  • WinCPICExtractEvent
The following is an example of how a WinCPICSetEvent verb appears in a CPI-C API trace: 
CPIC  WinCPICSetEvent request  - event 12345678
CPIC  
CPIC  Conversation ID = 000000AB
NOTE: This behavior does not affect the functionality of any CPI-C applications that call the WinCPICSetEvent and WinCPICExtractEvent verbs.

CAUSE

This behavior occurs because the CPI-C DLL (Wcpic32.dll) writes an incorrect conversation ID for the WinCPICSetEvent and WinCPICExtractEvent verbs to the CPI-C API trace files when CPI- C API traces are enabled.

For example, a conversation ID of 11223344 (Intel byte-swapped format) is incorrectly displayed in the trace file as 00000011. The correct format of the traced conversation ID would be 44332211.

RESOLUTION

To resolve this problem, obtain the latest service pack for Host Integration Server 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. This problem was first corrected in Host Integration Server 2000 Service Pack 1.

MORE INFORMATION

Host Integration Server 2000 and SNA Server traces are enabled when you run the Trace Initiator program (Snatrace.exe). For more information about the Trace Initiator program, refer to the Host Integration Server 2000 and SNA Server Online Documentation.
