RE: sql - Drop and Add constraints

Bill,

The number of access paths over a file should have little bearing on clear
time, no? The access path will be invalidated, the member cleared and then
the AP rebuild over an empty member. Reorg is a different case where data
still exists in the file.

Patrick,

It might be taking longer to do your CLRPFM because of a large increase in
the number of Logical Files and/or Views attached to the File/Table you're
trying to clear.  You may find that you have to do your CLRPFM using a
technique that many use with the RGZPFM - whereby they remove all related
access paths, reorg the PF (clear in your case), and recreate all the access
paths afterwards.  It is frequently faster.

Bill
