Need help with AS/400 DASD...
Manny
system ASP used is up to 82 percent. Is this critical? If so how can I
lower these numbers? Any help would be greatly appreciated... MR

Storage can drop your % quite a bit (30% one time for me). Opinions very on
what % is critical. I like to keep things under 80% myself. The Reclaim
Storage can take some time. On your box perhaps 1-4 hours. Is your %
climbing quickly?

theshold is set to 90%(unless someone has changed the settingJ). Once you
hit the dasd threshold you will receive critical storage messages in
qsysopr. At that point you will need to start removing objects from your
system as you will not be able to perform an IPL (if your system should go
down when when the theshold limit is exceeded you'll probably need IBM to
help you get it back up and running).
However, 82% is not uncommon for dasd utilization. I worked for many years
in a shop where we typically ran 85% on dasd utilization. It was sometimes
a challenge to find non-critical things to remove when we approached the
theshold limit. Also, I don't know if anyone uses SNADS anymore, but it
stops working when the theshold limit is exceeded.
You also need to be aware of applications that could sporadically send your
system over the theshold limit. For instance, our nightly backup will
write to journal recievers if the tape drive fails. The backup is fairly
large, and if we were in your situation we would exceed the theshold limit
by a large amount.

I think your biggest problem is lack of DASD to begin with. A model 170
will have anywhere from V4R2 up to V5R1 installed. Just loading the base OS
with basic lic. programs (TCP/IP, Client Access, Query, etc.) can total
about 4GB or 50%, not to mention adding any compilers or other development
tools. I would start just by adding more drives. 4GB drives are cheap, 8GB
drives are can still be a on the expensive side if cost is a huge issue.

Michael is saying is right than I have to agree with him. We only have
8gb of dasd. My next question is, how do I find the system value
theshold? How do I change it? Thanks again for your response.
I have to agree with Michael.

Use WRKSYSVAL for common system values
But the threshold value for asp is set through SST in the disk area
and the default I belive is 90%.

start (but active jobs will continue running). You can change the threshold
from System Service Tools (STRSST) / Work with disks but you should be very
careful. It might look tempting to up the threshold, but if a running job
increases disk usage (writing data to file or creating large reports) you
may run out of space causing the box to halt with the Attention light on...
10% of 8GB is not a lot.

You're already aware you don't have alot of DASD to work with. Check
the files in your libraries for deleted records. If you have a high
number of deleted records...reorg. the files. Also...watch your
journal receiver sizes. These tend to use alot of space if your not
regen. new ones and removing or saving old ones.
