RE: Insert performance

[Cary Millsap]

Rick,   Find out what kind(s) of buffer busy waits you have. MetaLink, Anjo Kolk’s YAPP paper, or Steve Adams’s book can tell you how to read the p1, p2, p3 values on the waits you see. Then eliminate the motive for the waits. The same documents will tell you how.   Cary Millsap Hotsos Enterprises, Ltd. http://www.hotsos.com Upcoming events: - Hotsos Clinic 101 in Sydney - Hotsos Symposium 2004 March 7–10 Dallas - Visit www.hotsos.com for schedule details... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rick Stephenson Sent: Tuesday, September 23, 2003 4:05 PM To: Multiple recipients of list ORACLE-L Subject: RE: Insert performance   I have already bumped that up quite a bit as well, but I still get many waits.   Thanks,   Rick Stephenson Oracle Database Administrator Ovid Technologies, Inc.

Is the sequence cache set to an appropriately large value? Justin Cave   I have approximately 6 concurrent inserts per second into this table which causes the primary key index to become a hot block.  This in turn causes "buffer busy waits".   I have increased initrans, but am not sure where to go from here   Any ideas would be appreciated,   Thanks,   Rick Stephenson Oracle Database Administrator Ovid Technologies, Inc.
