Common problems and mistakes when using FRS
Q:
Why is FRS recovery not working as expected? Possible symptoms include a return code of 4 or above, VSAM/FRS error codes in R15 and FDBK, or no records recovered for a file or files.
A:
There could be a number of causes.
- Ensure that the RECFM in FRS (F or V) matches the RECORDFormat in the file definition in RDO, and that they both agree with the DEFINE CLUSTER's RECORDSIZE.
- Check that the FRS TYPE (KSDS, ESDS or RRDS) is correct.
- Make sure that the journal is the correct one for the file(s) being recovered, that the JOURNAL DD SUBSYS and DCB parameters are correct, and if you are using a copy of the journal that it was copied with DFHJUP correctly.
- Ensure the VSAM file(s) you are recovering are exactly the same as they were when opened in CICS for the timeframe being recovered.
