RE: File reorganization

[Chris Bipes <rpg@xxxxxxxxxxxxxxx>]

With that large of a file and many logicals, I found it faster to RMVM on
all the logicals before the RGZPFM then submit to batch the ADDLFM.  The
adds can be submitted to a multi-threaded job queue.  The cutoff for this in
my rough guess is 1 million records.

Subject: File reorganization




I've got to reorg some files on the system. What is faster:

A. Reorganize files as:
     - remove logical's
     - reorg files
     - add logicals
or

B. Copy data out to temp file, followed by copying data back

Files are from 5,000,000 to 43,000,000 records and have logical files based
on them.

Answers would be greatly appreciated.
