Steps to Reproduce

Install Pega 7.1.5 on WebSphere Application Server 8 and DB2.

Root Cause

A defect or misconfiguration in the Pega operating environment

For users using the DB2 Version 4 drivers (db2jcc4.jar), it is necessary to set the custom connection property useJDBC4ColumnNameAndLabelSemantics to “false”.
For users using DB2 with WebSphere Application Server, the useJDBC4ColumnNameAndLabelSemantics property in the DB2 data source needs to be changed from a Boolean to an Integer and set to "2".

Note: The Data Source Custom Property names are case-sensitive.


Perform the following local-change:
db2jcc4.jar. to db2jcc.jar.
