Q183552: SNA DDM Service Terminates; Type Mismatch Errors

Article: Q183552
Product(s): Microsoft SNA Server
Version(s): WINDOWS:1.0,4.0
Operating System(s): 
Keyword(s): 
Last Modified: 21-JUL-2001

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

- Microsoft OLE DB Provider for AS/400 and VSAM, version 1.0, used with:
   - Microsoft SNA Server, version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you are accessing a mainframe file, if the LU6.2 connection is terminated
abruptly, the SNA DDM service terminates with an unhandled exception. Bad data
can be written to the mainframe file; also, when the OLE DB Provider reads bad
data from the mainframe, it crashes.

CAUSE
=====

The mainframe deallocates the LU6.2 conversation with CONV_FAIL_ABEND. The OLE
DB Provider, regardless, tries to interpret as application data the LU6.2
information returned from the mainframe. This results in an access violation.

STATUS
======

Microsoft has confirmed this to be a problem in Microsoft OLE DB Provider for
AS/400 and VSAM version 1.00, included with SNA Server version 4.0.

This problem was corrected in the latest SNA Server version 4.0 U.S. Service
Pack. For information on obtaining this Service Pack, query on the following
