The IBM DB2 driver can best be characterized as version-hypersensitive. It is not compatible across major or minor versions of DB2, including FixPacks. For this reason, we recommend that you use the file installed on the database server.
The IBM DB2 driver must be updated on the Identity Manager or Remote Loader server every time the target database is updated, even if only at the FixPack level.
The IBM DB2 driver does not support encrypted transport.
A version mismatch usually results in connectivity-related failures.
The most common problem experienced with the IBM DB2 driver is because of a driver/database version mismatch. The symptom of a version mismatch is connectivity-related failures such as CLI0601E Invalid statement handle or statement is closed. To remedy the problem, overwrite the db2java.zip file on the Identity Manager or Remote Loader server with the version installed on the database server.
It’s very difficult to diagnose and remedy Java-related errors on the database server.
Numerous error conditions and error-codes can arise when you attempt to install and execute user-defined stored procedures and functions written in Java. Diagnosing them can be time consuming and frustrating. A log file (db2diag.log on the database server) can often provide additional debugging information. In addition, all error codes are documented and available online.

Can’t start a manual transaction because of cloned connections.
An implementation anomaly that doesn’t allow concurrent statements to be active on the same connection causes the most common problem experienced with the SQL Server 2005 driver. Unlike other third-party implementations, the SQL Server 2005 driver can have only one java.sql.Statement object active at a time on a given connection.
If you attempt to use more than one statement object, the following error is issued: Can’t start manual transaction mode because there are cloned connections. This error can occur only if the driver compatibility parameter Reuse Statements? is set to Boolean True. As a best practice, never explicitly set this parameter. Instead, defer to the dynamic default value.
An alternative is to place the delimited property ;SelectMethod=cursor at the end of the URL string. For additional information on this issue, consult the following support article:
Article 313181 by Microsoft
Association values that contain UNIQUEIDENTIFIER columns are inconsistent between driver versions.
Earlier versions of the SQL Server 2005 driver returned a non-standard java.sql.Types value for native UNIQUEIDENTIFIER columns. To compensate, the JDBC driver mapped that non-standard type to the standard type java.sql.Types.BINARY because it best mirrored the native database type, which is a 16-byte value. This mapping results in a Base64-encoded association value.
Later versions of the SQL Server 2005 driver return a standard type java.sql.CHAR. This mapping results in a non-Base64-encoded association value, effectively invalidating all associations generated by using earlier versions of the SQL Server 2005 driver. This change effectively breaks backward compatibility.
The best solution to this problem is to continue using the earlier version of the SQL Server 2005 driver. If you must upgrade, remove all invalidated associations and reassociate all previously associated objects.
