Reclaim Storage (RCLSTG)
Jamie Rogers
Our AS400 programmer just left the company and we just found out that the
RCLSTG command was never done.
I am wanting to run the RCLSTG command but I am worried about the length of
time it will take to run.
Does anyone know how long this command generally takes, and if it can be
stopped after it has started.
Please reply to jro...@distican.com
Any help would be great.
Thanks
Jamie Rogers

How long is never?

My experiences ranges from nearly 2 hours to 10 hours. It's completely
depending on your system (e.g. processor speed, disk types & speed, available
memory, version, etc)

Please do not stop the process once it has started. Nobody will guarantee a
proper status after
killing this function.
I assume, that your company doesn't need a 24 hour, 7 days availability and
suggest you run the
command on a nice sunday morning (early) and go for brunch with your family.
Show up again in the afternoon.

PS. On some systems the success was great: we gained over 1GB diskspace on a
40 gig system

version are you running of OS400? The newer version (V3R2/V3R6/V3R7) do not
take as much time to run. I came from the S/38 days when running RCLSTG was a
last resort to fix a problem. I have run RCLSTG on a 2131 running V3R6 and it
only took about 1hour. I have also run it in about 2-3 on larger systems.
Just pick a weekend and start it up.

Hi,
however, you can check the disk space you will get after a RCLSTG before
you make it:
Submit RTVDSKINF in batch and -when the job ends- print the infos with the
PRTDSKINF cmd. In this spool you will find the diskspace for rclstg.

Hi,
I just run RCLSTG for a customer yesterday.(befor upgrade to RISC)
The last RCLSTG was in 1992 !!
It is an 9406-B50. with about 15Go.
I prepare me for a long time....
RCLSTG was finshed less than 1 houre !!!
I cannot give you a good answer.
You have to try
Good luck.

Hi,
RCLSTG must run in the controlling subsystem.
Prior to running RCLSTG you must end all subsystems.
Once started the only way to stop it would be to kill the job (not
recommended).
It is impossible to say how long it would take to run. All depends
on machine size, disk usage, time since last RCLSTG. I have seen
it run on an old 9404 B10 in twenty minutes and on an old 9406 B45
EIGHT HOURS!
RCLSTG is *not* the same as performing an IPL.

Yes, but isn't a RCLSTG just the same as doing an IPL?

Jamie,
Don't run RCLSTG. It's totally unnecessary. It is only intended as a
possible recovery method in some system errors. Run it only if an IBM rep
suggests it. Then argue with the IBM'r before doing it.
I have been an AS/400 PA since '89. I have only run it once. That was
only a test (in '89) to see what would happen. It took hours on end (on a
B30, '89 remember) and it did nothing.
Your programmer left without ever running it because he or she was smart.
YHS,
John W. Johnson
P.S. I you should decide to run it, don't even THINK about cancelling it.
Only IBM will be able to get you out of that mess.

We have run RCLSTG a few times in the past few years...It may or not
really be needed..but it only took an hour or so for each one...I think
it's basically a way that the 400 goes out there and makes sure all his
objects are accounted for, but I think he just kinda spins his wheels for
a while and doesn't do much of anything.

I'm reposting these timings I got from our RCLSTG. It did help.
=================================================
"I just ran my first RCLSTG in 3 years on the above machine. It only ran 1
hour 15 minutes and reclaimed about 1.5gb in disk space.
Was probably mostly from re-orging the QADB* files in QSYS, but it also
deleted over 8800 objects.
I was prepared for this to run 6-8 hours based on others postings. Maybe
it ran quick since we have many small disk units (1.97 gb) rather than
fewer large disk units and thus was able to do more concurrently?

Hi,
Don't agree at all.
It's important to run RCLSTG from time to time.
It does clean all lost or damaged objects, lost authority and permanent
adresses not in use any more. Especially on big system with thousand of
objects in use every days.
I'v done it on lots of systems with differents result but it has always do
some goods.
Sometimes it ran for hours and sometimes less an hour. All depends of the
number of object to scan.
It did do some good on system 38 in these old days when we use to do an IPL
5C. so it won't do any harm on as/400.
Go ahead.

:>> Jamie,
To determine if it is necessary to run the rclstg command
run the rtvdskinf command and see if anything shows
up in the category for objects that are not in a library.
The only way that you will be able to retrieve that
space is via the rclstg command.
Those objects will either be deleted or placed in the
library QRCL.
That is the main reason for the existance of this
function.

A rclstg should be run from time to time to perform general cleanup of
your system especially damaged objects. This becomes more important
after an abnormal system end. If you run the job on a regular basis
(we run the job every 6 months) the run time is greatly reduced.
