Re: Oh where has my disk space gone?

We converted from MAPICS I to BPCS about 15 years ago & I have been with the
same company that long.  If you are not already on the MAPICS_L here at
midrange dot com, I suggest you join since they probably have guidance on
managing MAPICS files.  You might also find information of value in the
archives of that group.

I do remember that the MAPICS documentation was first rate, compared to BPCS.
We had all 3 sets ... the behind the scenes IT staff manuals that explained
what MAPICS was doing & the layouts of various files & explanations of what
all those codes were for in various fields ... the general management manuals
that showed what needed to be done in each application for it to function
properly ... there was one of them for IT system support ... then there were
the run manuals for the people doing the hands on each application.

There was an expense associated with getting this documentation & generally
there were certain manuals that were VERY popular in great demand & 90% of
them sat gathering dust ... I would see if this stuff is available today on
like CD Rom.

One big problem I had was in staying current documenting modifications.
The MAPICS manuals were loose leaf notebooks & we were inserting pages with
information on what we had changed.
I could handle this using SEU but management wanted something that looked
professional, and I did not have direct access to word processing at the
office, so it was either do it at home which I did not want to do, or use
office people who were hopelessly back logged.

Many good ideas here in MIDRANGE_L posts ... we only got 12G of space & ours
been around 70-85% for the last year ... I am slowly bringing it down overall
by analysing what dead records are in our ERP that we do not need ... it was
over 100% a few years ago & that is a real bad trip you not want to take.

Do you have end users creating queries or some other method of reports &
inquiries on the fly?  We do create some work files with query.  Some of our
users are inexperienced in data base design & could create excessive query
work file collections.

Have you had some outside programmers working your place in the time period
of the growth?  I find that such people have their own standard practices &
can leave a trail of libraries & copies of software in excess of what I would
consider reasonable.

We use GO CLEAN to automate some clean-ups.
I set message queues to save stuff for 10 days ... like a week plus a weekend.
I tried to save system stuff for less than 30 days but it would not let me,
so I go in regularly to wipe it all out ... we do not have any system logs or
journals that are more than a few days old, except when there is a known
problem to investigate.

We also do IPL about once a month ... I believe the IPL does reclaim disk
space of deleted spool files & this explains to me why each IPL does recover
about 3% disk space that is gone again in a few days.  Prior posts here
warned that some of these options can take a while to run, so you might want
to search the archives for each RCL suggested to see if there are any gotchas.

I monitored WRKJOBTBL for a few months to see about adjusting what setings
advisable, but we now have our system on automatic tuning.

We encourage people to save their print outs until after backups, because if
something goes wrong before backup they may need to recover from audit trails
what they did.  For some applications we encourage people to save their print
outs for a week because it may take that long before it is evident that
something went wrong.

But beyond that, we remind people who have print-outs much longer, that we
are not backing up print-outs & they should delete those that they do not
need because large numbers of large print-outs do eat disk space & jobs
performance.

The accounting department used to keep their month end reports on-line for
months ... I suggested to them that from a navigation standpoint it might be
useful to move 100% of those for a particular end-month to an output queue
just for that end-month, and if they really really needed this stuff on-line
which we are NOT backing up, they should authorize purchase of a spool
archiving deal.

I say they used to do this.  They don't any more.  There was a dramatic drop
in people saving old spool files after we showed them how to transfer AS/400
reports to PC files that could be e-mailed or into Excel or Word document.

After Backup, I check the Job Dumps to see if there were any on a USER, as
opposed to on some IBM stuff & those on a USER I transfer to a different
spool, then I clear the entire JobDump Spool ... I do not get around to this
every nite.

If you not been doing this, WRKOUTQ gets you at list of all of them, then
scroll down & only view the Qs with significant numbers of contents.

I use dumps to *OUTFILE pretty heavily now compared to a year or so ago when
I first learned on midrange_L & AS/400 network how to work them.

One of them runs off the job scheduler several days a week to tell me how
many bytes we have of deleted records, and when the number climbs to say 5+
Meg that trips me into doing a general reorg that evening.  When I first
started doing this, we had over 500+ Meg in this situation.

I have another one that runs off the job scheduler to populate a work file of
the SIZES of our files in selected libraries.  It does this Monday 4 am ...
then another one is populated Friday 4 pm followed by a COMPARISON of the two
work files to give me some reports showing which files are getting the most
significant growth & other changes in sizes.

If you are not familiar with the IBM job scheduler ... GO CMDSCDE
be careful about putting any MAPICS jobs on this thing
When a user signs on, in our case BPCS, it sets up library list & a bunch of
conditions needed for menu options to work correctly.
When something runs off the job scheduler, there is no library list or all
that other stuff native to it, so to get your ERP stuff running off the job
scheduler, needs a programmer who has a keen understanding of what is going
on under the covers.

Our retrieve disk info is set to run very infrequently since I am now finding
that my outfile analysis is much more useful in analysing what files in most
need of cleanup.

I have an RPG program that reads an outfile of our files directory, that
prints a report on how many members it has that are empty & how many
populated, numbers of records there, for the big ones an SQL COUNT(*) those
older than a year & incidentally what is the oldest date in this file ... you
have to know file layout to do that.  I have been using this tool for the
last 6 months to prioritize what files in most need of old deadwood clean out.

I have found where there are members with zero records that have not been
accessed in over a year ... I have plans to say goodbye to them that I have
not actually implemented yet.

There is also an issue associated with those files that grew to millions of
deleted records before I figured that out & reorged them ... they may
actually be the capacity they were before I started regular reorg ... I may
need to downsize some.

Depending on your software package, you may have a month / year cycle in
which data grows to some size in some files, then gets cleared away at the
end of end-month or end-year processing.  For example, we keep our inventory
transactions history on-line for 365 days.  When we do our physical
inventory, that's several thousand transactions added in one day.  Now there
are alternative ways to do physical inventory that could add hundreds of
thousands of transactions.

We have people who are trying to figure out how to run the BPCS cycle
counting system.  I know that because I run the INV900 during EOM because
that task is fraught with risks of going awry & its first screen invariably
tells us that someone tried to do cycle counts this month & did not get the
task to a conclusion.  I have a suspicion this adds records some place, but I
have not yet taken the trouble to track it down.

Our General Ledger is currently done in summary format.  A new person in our
accounting department changed it to detail format, when noodling around
without reading the documentation.  I found out about it when they ran out of
Journal Batches before the end of the month.  Problem was solved, but here a
decision by someone who did not understand their department application led
to a short term dramatic rise in the volume of their transactions.

You have added 30% consumption in 2 months ... did you install some package 3
months ago & did it come with some system for estimating disk space needs?

Did the disk space consumption grow steadily, or did you check this
intermittently & suddenly notice it had jumped & you don't know if it came
all at one time.

I try to remember to check this story before & after implementing some new
application so I know what the impact is.

There are tons of computer magazines.  I find that News/400 recently
rebranded iSeries News to be the BEST & their iSeriesNetwork.com to be a
dynamite complement to midrange dot com, but there is a cost to subscribe.
We also get AS/400 magazine also rebranded iSeries Magazine which is FREE
from IBM.  This latter has decent tips & also good stuff on their web site
... you might check the general resources area off of this midrange dot com
main page for other links.

We get several BPCS newsletters ... there are probably some MAPICS magazines
out there.

You mentioned college classes.  You might try to schedule a trip to COMMON or
IBM technical conference.  IBM has great classes & you can take some of them
on-line.
http://www.iseries.ibm.com/developer/education/ibo/view.html?all

IBM offers classes all over the USA ... check out if any of these cities are
near you
http://www-3.ibm.com/services/learning/lsweb/educationcenters/

As for which classes would be of greatest value for you to take
http://www-3.ibm.com/services/learning/community/as400/

If you going to be doing several IBM classes
http://www-3.ibm.com/services/learning/us/

There also used to be a MAPICS UNIVERSITY

If you are any place near Evansville Indiana, our local *BASE user group
intermittently brings some IBM instructor to teach a class here to folks from
many organizations in our user group.  The AS/400 user group circulates
surveys to the membership to find out what classes there is an interest in.
