no db2, no websphere, just oracle and cron/perl/scripts.
I'll be hosting the Performance workshops again after a year off. This
might be a good time for those of you with good performance tools to
come in for some education. see
"http://velocitysoftware.com/seminar/workshop.html"; for more
information. This kind of diagnostics becomes much easier with a little
education. I would also recommend Performance Analysis 42 for which we
go thru in detail in the workshop:

Subject: Re: High cpu utilization on vm/linux LPAR
This could be just new year workload. Or someone is running some new scripts
that are consuming LARGE amounts of CPU. The data shows nothing strange in the
CPU distribution between servers:

And from a linux perspective, looking at the cpu by application, oracle is consuming quite a bit
- but it really looks like someone is running short perl scripts continuously that are consuming
large amounts of data. (*PROD is the group of linux servers making up production, so this is
across all servers) . The "init" bucket is a catchall for short term (less than 1
minute) processes who's parent process is init. Thus the high "children" use in INIT for
production.

From a couple of days one of our Linux LPAR are continuously using 100% of
two cpu. We are on EC12 with z/VM SSI 6.2, two IFL's CPU's, 61440 MB of RAM,
4096 Extended RAM and the guest are running on SLES 11SP2. Do anyone has
similar problems or there is a kernel update for this issue.
