After installing CA Recovery Analyzer for DB2 for z/OS (PRA), the Edit Parmlib function disallows any new Data Set names to be entered for the Master Catalog DSN. Receiving warning: PT656E: Enter one of the listed values.
The solution includes going into Edit Parmlib from the Post Install Main Menu option 1 - Set Up followed by Option 3 - Products. Choose the correct PTISYSxx for the installation and then select PRA - Recovery Analyzer. Scroll down to Volume Recovery Parameters and enter the required Master catalog DSN.
