Re: my system is sluggish and I don't why?

Try WRKDSKSTS.  I know you mention it but it is the best way to check for
IO performance....beyond that is some of the data kept in PFRT that could
also show you your utilization on your IOP.  Rare but it can happen....

Thankyou all for this thread ... it has communicated useful pieces of
information to this lurker.  I know a lot about some topics & pipe up but
my
mind is a bit sluggish on comprehending this topic.

Our system tends to intermittently run sluggish, in which I usually do not
nail down the causes.  In other words we run fine most days, but by the
time
it dawns on me that we had a blip in performance, the evidence as to causes
has also evaporated.

A few questions to add to the pot ... no urgency on answers.

There has been mention of disk activity as distinct from disk utilization.
I interpret this to mean
Disk Activity = how busy is the access to hard disk
Disk Utilization = how much of the disk space has been used up

Every place I have seen percent disk it has been percent of system ASP
which
is around 73-77 % of our 12 Gig ... whether I look in DSPSYSSTS, WRKSYSSTS,
WRKDSKSTS they all say pretty much the same # at the same time, although it
is mildly disturbing to me that this % should fluctuate so much ... we must
have some pretty big work files.
... I had thought the only indicator of disk activity was the I/O counts
like
in WRKACTJOB & WRKSYSSTS ... is there some other place that might show disk
activity as a percentage or if it is a healthy or unhealthy number?

When we upgraded to V4R5 we were prompted to start PM/400 which I thought
was
a freebie from IBM, but as soon as I tried WRKSYSACT, I got the message
about
this deal expiring in 70 days & could not find software key in among the
V4R5
papers, so am I wrong that this is a freebie?
