But I noticed you are still pointing to my library but at an address that has turned into a rather large embarrassment as it is no longer mine and no longer belongs to the Oracle community: Rather to some spammers.

My new website name is \Morgan’s Library\ which is at http://www.morganslibrary.org/library.html.
You will find a lot of new material there, all updated to 11gR2, as well as another pages where I have been posting demos called \How Can I\ (http://www.morganslibrary.org/howcani.html).

If you would have a few minutes up update your pages I would be very appreciative.

Thanks.

SR is closed as unresolved and there is nothing else to do.
Main problem from mine point of view is Intel Itanium CPU, configuration that is really rare, so I think there is no testing configuration on Oracle Technical support side.

SR is opened. Sent RDA reports and waiting on their answer. For now they say it looks like a new bug ….

When find out let you know here…

I’m not sure I’m understanding your question. Looks like from the output above that your lms processes are running in RR class at priority 41.

oracle 5566 1 RR 41 14:12 ? 00:00:05 ora_lms0_HAC4
oracle 5570 1 RR 41 14:12 ? 00:00:05 ora_lms1_HAC4

Have you opened an SR?

I have situation like in Metalink note but mine owners are OK.

old 9: and a.ksppinm like ‘\_%&1%’ escape ‘\’
new 9: and a.ksppinm like ‘\_%os_sched_high%’ escape ‘\’

How to fix LMS process to run in RR? I’m on Linux IA64and RHEL EE 5.3 so there is no support for this combination…even on Metalink!
I’m suffering node eviction without reason. After I set digiwait and make some configuration changes …now in last 10 days there is no eviction…even on heavy stress (800 sql connections)…
So I’m pretty desperate…in searching for the reason…

THX for any help or comment

Thanks for your detailed comments. Sorry about the trouble getting the site to accept them.

Interesting. The _os_sched_high_priority parameter appears to just ratchet the priority up within the RT/RR class. On linux with 10.2.0.4, a vlue of 1 = priority of 41, 2 = 42, 10=50, 20=60, etc… I think once you get into the Real Time class that moving the priority up will have little value. At that point I think you’d need to follow Riyaj’s suggestion regarding interrupt fencing / isolating LGWR. Thanks for pointing out the parameter and the Metalink reference.
