IF any commands entered in CA 7 r12 have data issues, run the new DBVR program. There is a sample of the JCL to run the new DBVR in JCLLIB member CA07N610. The CAL2DBVR program executed in the CA07N610 member uses PARMS to determine the action to take in the data base. To report on any discrepancies found in the r12 Datacom database you can use the CA07N610 member as it is (PARMS are: PARM='TRIG,RQMT,SCHD,XREF' , which will report on any problems found--and this can be run with CA 7 r12 up). If any problems are found in the Datacom data, they will show in a report. If errors are found, you will need to take CA 7 r12 down and rerun the DBVR program with the PARMS:
//DBVPARM DD *
the UPDT, DELR, and DELT PARMS will cause the DBVR program to 'fix' the issues found. You should then be able to bring up CA 7 r12 and retry the command without errors.
