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
