"How do I uninstall PN/400?"
Before uninstalling PN/400 from your iSeries, read the following reasons for uninstalling, and some things to think about.
REASON #1 "I didn't know there was anything useful."
We hear this frequently, but not only is there useful stuff, there is free
useful stuff. Since Performance Navigator is useful to different people
for different things, sometimes the business partners (who use it for
capacity planning) neglect to mention the end-user features. The reason
the business partners don't make this clear to you is usually just a matter
of focus. They are focused on a hardware upgrade. If you'd like to see
the free stuff, run Performance Navigator on your PC, and click
'Graphs/CPU/Priority'. If you'd like to learn more about what you can do,
there is a built-in tour, just click 'Help/Tour', or call us and we'll walk
you through the product.
REASON #2 "We don't have any performance problems."
or "We just upgraded so we don't have performance problems."
or "It's just a development machine, so we'll never use it."
Now is the perfect time to have PN/400 installed and collecting data. Some
day, something will happen, and instead of searching for the problem, the
answers will be at your fingertips. I can't tell you how many times we've
seen people do something as simple as installing a new release of software,
or maybe just applying a PTF, and performance takes a nose dive. Think of
it like a fire extinguisher. If the need arises, you'll be glad you have
it.
REASON #3 "We do it ourselves."
Believe me, I know working with iSeries performance is one of the fun jobs
in the shop, and no one wants to give up their performance methodology, but
I guarantee there is no home-grown application does even a fraction of what
Performance Navigator does. You don't have to replace your methodology
with ours, we'll coexist. Think of it as another tool in your belt.
REASON #4 "It uses too much CPU and/or too much disk space."
These are common misconceptions. The truth is that the overhead is
minuscule, less than one tenth of one percent of the CPU and a couple
hundred megabytes of disk. Furthermore, Collection Services may be running
even without PN/400 in which case there is virtually no additional
overhead. And to top it off, since PN/400 collects data on every job and
every library, we can prove the overhead is insignificant.
Before you uninstall PN/400, consider the following, it's free, it's
useful, the overhead is minuscule, and the benefits are potentially
invaluable.
Note: After removing PN/400, Collection Services (part of OS/400) may still
be collecting data. If this data is collected, and not managed, your
system will fill up. If necessary, to end Collection Services:
CALL QYPSENDC ('*PFR ' X'00000000')
Note: There are six blanks after '*PFR' and before the ending quote
