I don't know if changing my the split load from 80% to 70% or if running
a "RESIZE [filename] DYNAMIC" command (or both) did the trick, but one
of the batches that has been taking up to two hours to complete finished
the other night in under 10 minutes.

Thanks a ton.

Subject: RE: [U2] Badly overflowed Dynamic files

Overflowed groups take longer to read, so you want to reduce the number
of such groups. Is the size of this file roughly constant, or does it
just slowly grow?

If it's roughly constant, try setting a MINIMUM.MODULO at around
900,000. It'll hopefully break up a lot of your badly overflowed groups.
Or change it away from a dynamic file to a hash-type that better suits
your keys.

If it grows steadily, try REDUCING your split figure - maybe 70%. Again,
that will increase the number of groups, and hopefully reduce your
number of overflowed groups.

Lastly, I was going to suggest looking at your block size and large
records, but I notice you don't have any.

Cheers,
Wol
