Oh come on now... ;) Your other answer about the Mgt Central collections
went a long way towards explaining it!

Re: RCLSTG (Was: Preventative Maintenance For AS400)
Just wondering why you run the RCLSTG that frequently...

We have a machine that we run RCLSTG on every 8 weeks. We used to do just
the RCLSTG on one 8 week rotating schedule and the full system save, etc
on another 8 week rotating schedule because the RCLSTG took too long.
After we upgraded from the 820 to the 520 it's not the problem it used to
be and they're done on the same schedule. RCLSTG dropped from an average
of 13 hours down to 4. Another one of those fantastic performance
increases you get when you drop your number of disk arms from 42 down to
7.

Re: RCLSTG (Was: Preventative Maintenance For AS400)
Wow... that's the type of RCLSTG horror story i've rumours of, but never
heard any specifics about! I'm wonder how common these types of RCLSTGs
really are... i'm betting Larry, Al, and some of the others might have
some
idea...
I've always been lucky to end up with the 2-4 hour ones.

I was always in the "run a RCLSTG before very upgrade" camp, but we just
had a bad experience with our last RCLSTG. We're getting ready to
upgrade V5R2-->V5R3 on an 810 with 4GB main storage, 225 GB internal
DASD at 66% and 565 GB fiber-attached shark external DASD at 69%. The
last RCLSTG was run two years ago and took about two hours. We haven't
had any system crashes in this time, however the external DASD was added
after that and has about 7M documents stored on it. I SWAGed a
guesstimate of 8 hours and requested 24 hours of downtime to run the
RCLSTG.
The first part of the RCLSTG took about 24 hours. (to get to 100%) Next
it sat at message CPI8218 - Directory recovery in progress for about 10
hours before going on to message CPIA916. After determining that we
were going to miss our SLA Monday morning the boss ordered an abort. It
only took about a minute to end after an ALT SYSREQ 2 and then I did a
RCLSTG *DBXREF, which only ran about 6 minutes. Then I IPLed (B-N) and
all looked normal, a *FULL restart went very quickly.
There were 12 objects in QRCL: 2 data queues and 9 user spaces beginning
with Q, and 1 file (EKDDSPOBJD, which may have been a WAF temp file as
it no longer exists or seems to be needed.) There were no /QReclaim or
/QOpenSys/QReclaim directories.
The bottom line is that it is unlikely that we will run a Reclaim
Storage again, at least not until we have an HA environment with a
backup production LPAR.

I work at a large (8 systems/23 partitions) iSeries datacenter and they
have
not done a RCLSTG in well over 10 years.
They simply say that they can't be down that long. They also feel that
since they replace machines on about 3 year cycles they are never that
over
due for the cleanup. I'm not totally in agreement but they run OK. I
if
you run RTVDSKINF then PRTDSKINF *SYS look down the report for the line
'Storage affected by RCLSTG'. It should show the impact of objects to
recover/cleanup.
