If looking for an alternative to the traditional IDCAMS REPRO for the
reorganisation of VSAM(and IAM) files, Innovation Data Processing's FDREORG
solution might be worth looking at:
http://www.innovationdp.fdr.com/products/fdrreorg/
Apart from being able to offer significantly better performance for file
re-organisations compared to that of using IDCAMS , it also allows for an
"intelligent" approach to running REORGS by being able to specify a number
of different criteria by which the file should be re-organised and
potentially eliminate un-necessary REORGs.

Yes John... As far as I know, both REPRO and EXPORT result in a reorganized
VSAM dataset.
While you're looking at alternatives, you may wish to consider Innovation's
IAM. We are quite happy with it.

Thanks, Alan.
How about IDCAMS EXPORT / IMPORT? We are looking at what it would take to
replace CA-FAVER. It is a good product, but we are looking at possible
alternatives. IDCAMS is __slow__!

Hi John,
I don't expect that it would. As far as I know, DF/dss "logical" processing
is aware of datasets and "records" (i.e. blocks) but doesn't usually concern
itself with the content of these datasets. There are two exceptions that I'm
aware of:
1) DF/dss can change the amount of unused (pad) space in a dataset
2) DF/dss can change a PDS into a PDSE
I believe that if you want to "reorganize" a VSAM dataset, you'll have to
use VSAM REPRO (which consolidates split CIs and CAs).
Cheers,
Alan
