And I thought Oracle said you didn't have to worry about how many any more. I didn't exactly blame LMTs I just said there were a lot of extents. Not my app. Thanks for info -----Original Message----- From: Dogan, Ibrahim - Ibrahim [mailto:Ibrahim.Dogan@xxxxxxxxx] Sent: Friday, April 22, 2005 11:46 PM To: Wolfson Larry - lwolfs; oracle-l@xxxxxxxxxxxxx Subject: RE: LOCALLY MANAGED EXTENT PERFORMANCE Do not use uniform sized LMTs for volatile tables since you may end up having a table/index with thousand of extents.. More important, don't blame LMTs for it.. If you use AUTO extent allocation instead of uniform size, you won't have problem...
