After applying maintenance to r20, some utilities are showing as excluded in RC/Migrator Model Services. Users are not able to activate the excluded utilities.
Also a strategy analysis may fail with the following error:
RMA209E ALL UNLOAD UTILITY MODELS EXCLUDED, NO UNLOADS GENERATED
RC/MIGRATOR ANALYSIS TERMINATING
Release : 20.0
Component : CA RC/Migrator for DB2 for z/OS
This is a known problem on r20 and is resolved with PTF LU00914.
The utilities will be re-activated automatically after applying this fix. There should be no need for any manual intervention.
