Hi,

If this is a 11i system, then make sure DCE products for 11.0 are installed on it.

swlist -l product |grep -i dce

Shouldn't list anything that says 11.00 in the version.

If so, you will need to install 11i version of them from your OS CDs. After re-installing it is a good idea to reboot the system as there are few processes that would need to be restarted.

If the DCE versions are good, then look for patches in itrc.hp.com.

In either the case, ensure you have a good make_tape_recovery tape or ignite image.

Hi,
Please post the sar -u and sar -d outputs. The high cpu consumption may also as a result of memory pressure on the system. Use measureware or glance for further analysis.

Hi,

It seems to me, you switched off a terminal where some X applications were running. The applications work now in a wrong mode.
Kill them and this will decrease the CPU load.

I installed OVO two weeks ago no problems.. we rebooted over the weekend..now this..
It's okay to kill swci and samd ?

Did you install DCE KT Tools along with OVO agent?. If so, I believe you might have installed 11.0 version of KT tools. Your swlist will confirm it.

samd is used to configure services such as Distributed Print Service on the remote systems. 'swci' is part of DMI - Desktop Management interface that I have not seen many people using it. If you are ok with not having them, you can disable them. samd is run through inittab. So, you will need to comment it out and run 'init q' to get rid of it. swci can be terminated using /sbin/init.d/Dmisp stop command. Edit /etc/rc.config.d/Dmiconfig to permanently disable it.

DCE-CoreTools B.11.00.10 DCE-CoreTools
DCE-KT-Tools B.11.00.10 DCE-KT-Tools

There the problem is. You would need to re-install DCE-CoreTools from Application CDs (Look at CD_TABLE_OF_CONTENTS after mounting any of the CD. You will also find DCE-KT-Tools there as I don't remember if there is any such for 11i. But I believe you don't need KT-Tools for OVO agent for atleast 6.1 version.

That needs a reboot ?

Re: High CPU Usage.. Top output below.. Please help.

Sridhar Bhaskarla — Mon, 21 Jun 2004 16:00:54 GMT

It doesn't. However, I suggest you to install the latest DCE patch also after reinstalling DCE-Coretools. It is a good idea to reboot. Last time, you didn't see the problem until you rebooted the system is due to the same reason. 'swci' and 'samd' were using the old DCE libraries until you rebooted the system. After reboot, they started using the new (actually old 11.0) libraries and hence you started seeing the issue.

Meanwhile, disable these two processes. When you get a chance, do the work the reboot the system. But make sure you have good make_tape_recovery tape in case if you run into issues.

Hi,

When you get a chance to reboot the system, install the latest (but recommended) DCE patches and then reboot. For the time being, close down the processes.
