The upgrade process for CA Datacom/AD involves a step to install and configure the new version of the software, followed by possibly other steps to migrate the application database to the Multi-User Facility (called MUF) for this new version. This migration is made using job AXPOR01, which is customized for each database that is migrated.
While there are instructions in the JCL for AXPOR01 that will ensure a successful migration, if these are not fully understood, it is possible to receive an error and an abend in the DDRTVBAS step. The job log might show messages similar to these:

This problem is typically caused by not using the correct loadlibs in this step as identified in the JCL instructions. In the AXPOR01 JCL for the DDRTVBAS step, the shipped (uncustomised) version has:
//DDRTVBAS EXEC PGM=DDRTVCAT,REGION=2M
// INCLUDE MEMBER=B14STLIB
// DD DISP=SHR,DSN=PRODAD.TARGET.LOADLIB
and the flowerbox instruction #13 says:
//* 13. PERFORM A GLOBAL CHANGE OF "PRODAD.TARGET.LOADLIB" TO THE
//* LIBRARY THAT CONTAINS THE DDRTVCAT BASIS MODULE.
Following the instruction #13, the PRODAD.TARGET.LOADLIB value will be changed to the loadlib for your application that uses CA Datacom/AD. For example, if using the CA Workload Automation Restart Option for z/OS Schedulers product (casually called CA 11), you should change PRODAD.TARGET.LOADLIB to the CA 11 loadlib that contains the module called L7601.
Once this has been corrected, it is recommended to rerun this AXPOR01 job from the beginning.
