Every Monday, PDTBATCH job fails with a RC=12, then the job will run fine with data collected from new interval.
Release : 20.0
Component : CA Detector for DB2 for z/OS
The required solution for this is probably a DFSORT(IBM) fix than a Detector(PDT) fix. In the meantime, you may want to try this circumvention from z/OS 2.1 DFSORT Messages, Codes and Diagnosis: "If the error persists, you can bypass it, in some cases, by specifying the NOBLKSET option temporarily to force DFSORT to use a different sorting technique."
