Re: RGZPFM Question -- MIDRANGE-L

Al,

I would agree with that as well. Going from being I/O bound to CPU bound is not much improvement.

Happy New Year to all!

Regards,

Mike Shaw

Folks,
Over the holiday one of our developers deleted 20,000,000 records from a physical file as they were no longer needed. This HUGE physical file (
even

after 20 M records deleted) has 19 logicals built over it. On Sunday morning, a scheduled job ran (which was not planned), that did a RGZPFM

over

this mess. The end result was that it put an 870 8-Way running SMP on

it's
knees for 13 hours.   No matter what I tried, I could not get the
IDX-<access path name> running under QDBSRVxx jobs to ease up.
I did find the following Knowledge Base document (after the fact):
http://www-912.ibm.com/s_dir/slkbase.NSF/ce197905697c4c6086256a4f007978f7/17
bb5f5d63273150862565c2007ce9e5?OpenDocument
Now for my $64 K questions: Had I used the EDTRBDAP command, could I
have

put the active access path rebuilds on hold? Would the active IDX

entries

have to have completed before the *HLD entries would have taken effect?

I

am trying to understand how I could have got this under control in the

least

amount of time.
Mike,
You could have used the RMVM command to remove the members from all of
the logical files.  Then do the RGZPFM.  Then ADDLFM one logical file
at a time in a batch CL.
