Mike - did you consider changing the sysval QQRYDEGREE (parallel
processing option) to *NONE. If the change takes effect immediately
(that's a big IF), then the RQZPFM would only run on one of your 8
processors, but the down side is the reorg would have probably taken
much longer. Just a thought.....

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/ce197905697c4c6086256a4f007978f 7/17 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.
Any and all comment appreciated. Thanks!
