The system is Power 880. Its a vio client. The npiv is configured.
Network cards are FCoE Adapter on vios sharing one port to only 2 lpars.
The vios level is 2.4.2.20 and the DB oslevel is 7100-03-04.
The software is oracle 11G
The storage is assigned via IBM SVC cluster and IBM fs800 is the storage. I have only this much info anything else i need to ask storage admin.
The IBM sddpcm drivers are installed and each storage data volume has 4 active paths.
The OS volume has 2 different fcs paths.
There is no cluster for this server.
As this is a IBM storage and device drivers installed there are no pseudo disks.
The sample output of iostat as below.
==================================================================================================== ===================
The hosts entries are managed by /etc/hosts file only and no dns server is configured. The authentication is only for local accounts so no external authentication.
The ipcs output as below

Hello everybody.
I have a problem with my AIX 5.3. Recently my unix shows a high cpu utilization with sar or topas.
I need to find what I have to do to solve this problem, in fact, I don't know what is my problem.

About 4 years ago I wrote this tool inspired by Rob Urban's collect tool for DEC's Tru64 Unix. What makes this tool as different as collect was in its day is its ability to run at a low overhead and collect tons of stuff. I've expanded the general concept and even include data not available in... (0 Replies)
Hello Friends,
On one of my Solaris 10 box, CPU usage shows 100% using "sar", "vmstat". However, it has 4 CPUs and prstat and glance are not showing enough processes to justify high CPU utilization.

Hi All,
While creating zone we will mention min and max cpu cores, like
add dedicated-cpu

end
Ques1:
Suppose thing that non global zone uses only minimum cores at particular time What the other cores will do, Will it shared to global zone?

We have a DB server which is constantly utilised above 95% above.
This is becoming nuisance when the monitoring team frequently calls to check on it. Frankly I do not know what to tweak or even interpret the outputs.
I noticed constant 30 to 60% in wio column of the cpu utilisation.

Hi all,
Been reading a lot of the cpu load and its "analogy of it to car traffic path of expressway"
From wiki
Most UNIX systems count only processes in the running (on CPU) or runnable (waiting for CPU) states. However, Linux also includes processes in uninterruptible sleep states... (13 Replies)
