John, We don't plan to use MTS for 11i just during the AUTOUPGRADE process from 10.7 to 11i. We found that it runs 20% faster with MTS because the workers logon/off thousands of times.
And yes MTS is configured with with large pool. Thanks for the feedback. -----Original Message----- Sent: Friday, June 28, 2002 1:33 PM To: Multiple recipients of list ORACLE-L Mary Jo, Are you sure that MTS is supported in 11i (or at least in an upgrade)? My understanding is that it is not - the work required is just too heavy for MTS.... As a start, you could take out MTS, and try and use IPC if it your APPL_TOP and Oracle DB are on the same server. There is an incredibly _huge_ number of jobs to be run through the workers and tons of SQL is loaded. I wouldn't be surprised by lib cache/row cache related waits. How many workers did you use? The recommendation is # of cpus + 2, although I would bump that number up just a little. Is LARGE_POOL_SIZE configured? More questions than answers, but I hope this shines a light in the right direction!
