SYMPTOMS

When you run some queries for a DB2 database in Microsoft Host Integration Server 2009 or in Microsoft Host Integration Server 2010, the queries might not return any values. However, the OLE DB provider for DB2 may incorrectly miss the End-of-Row marker. Therefore, the provider enters an infinite loop when the Continue Query (CNTQRY) and Query Answer Set Data (QRYDTA) messages are sent. This infinite loop causes the provider to stop responding.
