Root Cause



The root cause of this problem is misconfiguration in the PRPC operating environment. DB2 environments using JDBC 4.x drivers require custom setup.


Resolution



This issue is resolved through the following local change: For a database with DB2 Version 4, you must set the custom connection property useJDBC4ColumnNameAndLabelSemantics to "false". Please see our product installation manuals for further details.
