IBM DB2 Client for Windows
Posted on 2009-07-01
We are using IBM DB2 Client 9.5 for connecting to a DB2 server from SQL Server 2005/2008. We have created a datasource and a linked server in SQL Server for that. A query against the DB2 is working fine. But we are getting the below error after we run a query against DB2 using MSDASQL (Microsoft OLEDB provider for ODBC) provider and then run the query using IBM DB2 client.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "IBMDADB2.DB2COPY1" for linked server "DB2OLEDB2" reported an error. The provider reported an unexpected catastrophic failure.
Msg 7320, Level 16, State 2, Line 1
Cannot execute the query "Select * from db1.user.table1" against OLE DB provider "IBMDADB2.DB2COPY1" for linked server "DB2OLEDB2".
This issue is getting resolved when we restart the SQL Server. And the issue resurfaces again when we run the query using MSDASQL provider. The MSDASQL provider always works fine but not IBM DB2 Client. Are there any compatibility issues or any other issues between MSDASQL and IBM DB2 client? Can someone please give some insight on this?
