RE: PF with lotsa LFs

["Mark A. Manske" <mmanske@xxxxxxxxxxxxxxxxxx>]

Do you have the luxury of having SQL on you system so you can build
dynamic sqls right in your RPG inquiry programs?

Otherwise there is the old opnqryf dynamic builds - as for overhead,
I have never gone that far, but, I do have a logical built over 5
rather large physical files - we get bit HARD if we do a re-org
on any of those files (by large I mean each file has well over
10 million records -  to some that would be average)

And these physicals each have 10 logicals over them - the
hits seem fine, but we took a lot of page fault hits until
we added memory and adjusted our pools.

Subject: PF with lotsa LFs


Anyone ever have a file with 100+ logicals?

The design choice I'm facing is either fewer LFs but more complicated
inquiry programs & potential performance penalties vs. having many logicals
with simpler and quicker programs (less file reads).

Any wisdom on this?  Pitfalls?  Considerations?


Thanks...

Tom
