SYMPTOMS
A call to the GetLiteralInfo function may return an incorrect error message in the Microsoft Host Integration Server 2000 DB2 driver. When SQL Server Distribution Agent cannot synchronize with the IBM DB2/MVS heterogeneous subscriber, the synchronization ends. You may receive the following error message:

Agent message code 20084. The process could not connect to Subscriber '< >'. Message: Replication-Replication Distribution Subsystem: agent < > failed. The process could not connect to Subscriber '< >'.

[12/12/2004 9:16:31 PM] .distribution: {call sp_MSadd_repl_alert(3,,  , 14151, ?, -1,  , N' ', N' ', N' ', ?)} ErrorId =  , SourceTypeId = 1 ErrorCode =  ErrorText = ''

Additionally, you may receive the following error message:

0x80040E21 (DB_E_ERRORSOCCURRED)

However, you are supposed to receive the following error message:

0x00040EDA (DB_S_ERRORSOCCURRED)

This problem occurs in Host Integration Server 2000.



CAUSE
This problem occurs when you perform SQL Server Transactional Replication to a DB2/MVS heterogeneous subscriber. You do this by using the Host Integration Server 2000 DB2 driver. SQL Server Distribution Agent makes a call to the GetLiteralInfo function to obtain information about the literals that are supported by the DB2/MVS server. Sometimes, the DB2 OLE DB driver may return an incorrect HRESULT to SQL Server Distribution Agent. This causes SQL Server Distribution Agent to prematurely end.

Note There is a small timing window where a &quot;buffer overread&quot; can occur in the call to the GetLiteralInfo function. This is true if one of the parameters that is passed is in the DBLITERAL_QUOTE literal.
