DOCUMENT:Q279341 08-MAY-2002 [sna] TITLE :OLE DB Provider for DB2 Hangs When Calling Stored Procedure PRODUCT :Microsoft SNA Server PROD/VER::4.0 SP3,4.0 SP4 OPER/SYS: KEYWORDS:kbDSupport kbsna400sp3 ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft SNA Server, versions 4.0 SP3, 4.0 SP4 - Microsoft Host Integration Server 2000 ------------------------------------------------------------------------------- SYMPTOMS ======== The OLE DB Provider for DB2 hangs when a Stored Procedure is called if the output parameters returned by the Stored Procedure are larger than 32 kilobytes (KB). The symptoms that are seen by an end user when this problem occurs may vary depending on the application that generates the OLE DB Provider's call to the Stored Procedure. In the reported instance of this problem, the Microsoft Visual Basic application that initiated the call to the Stored Procedure halted and stopped responding when this problem occurred. CAUSE ===== Output parameters returned by a Stored Procedure that are greater than 32 KB in size cause the memory that is used by the OLE DB Provider for DB2 for communication purposes to be exhausted.
