Since the 400 went to 64 bit addressing, you no longer routinely IPL your
system.  For just about everybody, IPLing when you PTF or do a new release
is sufficient.

I do hear from some people that IPLs clear up disk usage, and if that's
true, it's likely the fault of a poor system design.  When I have noticed
this trend, the disk utilization is usually reused immediately after
production work stops, gets to a specified point and stays there.

I do a 21 every other weekend on both my 400s. I know this may be overkill
as my
data libs on the production box are backed up daily but it only takes a
hours and gives me the warm fuzzies.  I do ptfs, ipls, and breakfast
on the same days and sometimes will do an 'extra 21 save' if there has been
happening on a box.  Now if my webserver ever starts getting any hits on a
sunday morning,  I'll have to explore other strategies...
