CA Datacom 14.0 DDTRSLM utility failed when run with REGION=4M with return code 16 and error:
DDTRS0015E MAINTREC FAILED DSF COMMAND, RC: 199
This situation occurred when the CA Workload Automation CA 7 Version 12.0 CAL2JCL job AL2DCA40 was run with REGION=4M instead of REGION=0.
Problem was resolved with REGION=0M on the JOB and EXEC statements.
The CA 7 job AL2DCA40 flower box comments do specify REGION=0M:
//* CA Datacom utility DDTRSLM works best with REGION=0M
//* specified on **BOTH** the JOB and EXEC statements.
