Steps to Reproduce

Install Pega 7.1.8 on DB2.

Root Cause

The root cause of this problem is in a third-party product. The IBM JVM on AIX has an issue with the UDF jar files.


This issue is resolved through the following local-change:

Perform the installation by using command line scripts to load the UDF jar files prior to installation and then bypassing this process during the install itself. This is documented in PDN article:
The property for bypassing is, 'bypass.udf.generation' in the file.
