9.2.0.6 (64-bit) on Solaris. This question is in continuation of the problem that I had sent a note out to this DL last Friday. I finally opened a TAR last night with Oracle as it seemed like an Oracle issue to me. ________________________________ From: racdba-bounce@xxxxxxxxxxxxx [mailto:racdba-bounce@xxxxxxxxxxxxx] On Behalf Of Sudhi Sent: Tuesday, August 30, 2005 9:29 AM To: racdba@xxxxxxxxxxxxx Subject: RE: 11i RAC question Increasing the priority of LMS/LMD processes is a known thing for performance. I'm not sure about the "_gc_defer_time". KG or Anand should be aware of it. BTW what version of RAC ? Thanks, -Sudhi. ________________________________ From: racdba-bounce@xxxxxxxxxxxxx [mailto:racdba-bounce@xxxxxxxxxxxxx] On Behalf Of Hameed, Amir Sent: Tuesday, August 30, 2005 6:55 PM To: racdba@xxxxxxxxxxxxx Subject: 11i RAC question Is there anyone in this DL running 11i with RAC? If yes then can you please tell me if you had to make the following settings to address some cache fusion issues: + alter system set "_gc_defer_time"=0; + Increase the priority of LMS process ( renice -n -p <PID of LMS process> ) I have a TAR opened with Oracle and they are suggesting this solution. I want to make sure that the solution is not custom and is a generic one and has just not documented. Any feedback will be appreciated. Thanks Amir
