I'm having a problem with DB2 transactions. I'm using C# and IBMDA400 (Client Access) to access the DB2 (which is on AS400 machine).

OleDbTransaction tran = conn.BeginTransaction();

returns:

CWBZZ5010 Communications error occurred with system 10.1.1.5.

I've tried all isolation levels, but the message is the same.

Can anyone help me, please?
