SYMPTOMS
When you update the OS version on the AS/400 computer to version 4 release 4 (v4r4), the connection between SQL Server and DB2 on the AS/400 computer no longer works. Event alerts are logged in SQL Server.



CAUSE
With versions of SNA Server 3.0 (all service packs) and SNA Server 4.0 (including Service Pack 1), the StarSQL driver for ODBC connections is provided; however, these versions of the StarSQL driver are not compatible with OS/400 v4r4. The version numbers included in SNA Server are as follows:

SNA Server 3.0: version 2.27.10.18SNA Server 4.0: version 2.40.08.05SNA Server 4.0 SP1: version 2.52.05.01



WORKAROUND
In SNA Server 4.0 SP2 and later, Microsoft provides the same functionality with the OLE DB provider for DB2. This driver supports both OLE DB and ODBC connections through both APPC and TCP/IP protocols. The behavior described in the "Symptoms" section of this article has not been observed with the ODBC driver included with SNA Server 4.0 SP2 and later.
