After converting to r12/12.1 if there are any data errors attempting to do CA 7 commands, you can run the new CAL2DBVR program in CA07N610.
If any commands entered in CA 7 r12/12.1 have data issues, run the new DBVR (CAL2DBVR) program.
Use member CA07N610 in hlq.JCLLIB to execute the new CAL2DBVR. Run with the existing PARM='TRIG,RQMT,SCHD,XREF' which will report on any discrepancies found in the database. CA7 online can be up and running when executing CA07N610.
To correct the errors found in the report, run the CAL2DBVR with the following PARM below. Note that CA7 online must be down to make the updates.
//DBVPARM DD *
The UPDT, DELR, and DELT PARMS will cause the CAL2DBVR program to 'fix' the issues found. You should then be able to bring up CA 7 r12/12.1 and retry the command without errors.
