Update manager rollback feature fails for prrampart.jar



On PRPC 6.2 SP2, with the update manager rollback feature installed as well as the required update manager hot fixes, rollback fails for prrampart related jar and class files and the pr_engineclasses table is not updated. Implementing HFix-9559 works as expected, however, rolling back the changes causes invokeaxis2 to fail to compile correctly.


Failed to compile generated Java com.pegarules.generated.activity.ra_action_invokeaxis2

Steps to Reproduce

Install HFix-9559 which includes changes to the prrampart jar and class files. Rollback HFix-9559 to observe the issue.

Root Cause

There is a problem in processing this case. Other jar and class files are rolled back appropriately.


This issue is resolved in the update manager of Pega 7.

To remediate the problem after rollback, execute the below delete statement and restart the affected servers.

delete from pr_engineclasses where (pzjar like '%prramp%' or pzclass like '%prramp%')  and pzlastmodified='2013-02-22 06:41:22.000'
