George, aren't you a Servergraph user? Doesn't it give you what you
need?   I don't know what you're trying to accomplish here, but
Servergraph handles the usual culprits...

I think you'll need a separate query for each utilization range.
At least, I haven't thought of a good way to iterate.



select stgpool_name, count(*) as "60% < utilized < 70%" -
from volumes -
where devclass_name='LTOCLASS4' -
  and pct_utilized>=60 -
  and pct_utilized<70 -
group by stgpool_name -
order by stgpool_name

Etc...


You could maybe nest several of these selects inside another select,
but
that can be pretty cumbersome.

Subject: [ADSM-L] Summarizing Tape Utilization

Greetings everyone,
I have a/an SQL Select question.

Most of my TSM Servers are at 5.5.1.0, one is at 5.5.2.0

I am trying to count the number of tapes with a percentage
utilization in
brackets of 10 percent.  In other words, how many tapes with
utilization
between 100 and 90, 90 and 80, and so forth.

I first tried:
select count(volume_name), pct_utilized, stgpool_name from volumes -
where
(pct_utilized between 100 and 90) or (pct_utilized between 90 and
80) or (pct_utilized between 70 and 60) or (pct_utilized between 60
and
50) or (pct_utilized>50)-
group by stgpool_name, pct_utilized

Although the statement functions and returns valid data,  it is not
what I
expected.  I mistakenly expected it to count all the tapes within
each given
range.  What it really does is count tapes with distinct pct_util.
I might as well not have specified the ranges.  The only tapes it
counted
cumulatively were of the exact same pct_util.

Unnamed[1]     PCT_UTILIZED     STGPOOL_NAME
-----------     ------------     ------------------
         1             59.4     C_TSMSERVER_TAPE
         1             68.7     C_TSMSERVER_TAPE
         1             78.2     C_TSMSERVER_TAPE
         1             79.5     C_TSMSERVER_TAPE
         1             99.9     C_TSMSERVER_TAPE
         1            100.0     C_TSMSERVER_TAPE
         1             66.0     NASPOOL

If I select for a count for greater than or less than a particular
value, I
get the kind of count I expect.  I had expected "between" to do
similar work
but be less klunky.

select count(volume_name) from volumes where pct_utilized<100 and
pct_utilized>89


The other option I tried was CASE, WHEN, THEN:

select count(case when pct_utilized between 100 and 91 then 1 else
0) from
volumes and, select count(case when (pct_utilized between 100 and
91) then 1
else 0) from volumes

Those failed for syntax errors.

Is there a clean way to do this?
