CA/1 - Add FDR/ABR as an EDM (External Data Manager)

Products

• CA 1 Flexible Storage

Issue/Introduction

Need to add FDR/ABR as an EDM to CA/1 processing.

Environment

CA/1 (all releases) running with FDR/ABR 

Resolution

To establish FDR/ABR as an EDM you need:
- FDR/ABR program must be APF authorized and linked AC=1.
- FDR needs to call TMSARCTV
  (needed so that when FDR no longer needs the tape it can call the exit for CA1 to expire and then scratch it)

- Set up TMOEDMxx member with:
  EDM=FDR,DSN=-,PGM=FDRABR
  (The EDMID can be up to 4 bytes then restart TMSINIT)

- Correct existing FDR/ABR volumes:
  * Run TMSAGGR to PURGE the DSNBs
    (this needs to be done for all existing FDR/ABR volumes you want to control with EDM)
    VOL nnnnnn,PURGE

- Existing tapes also need to have Tape chains broken and control fields updated:
  * Run TMSUPDTE with (again for all controlled volumes):
    VOL=xxxxxx,NODSN,NOCHAIN
    REP VOLSEQ=1,EXPDT=PERM,EDMID=FDR
    REP 1STVOL=HEXZEROS,NEXTVOL=HEXZEROS,PREVVOL=HEXZEROS
    OI FLAG3=20
