Bunyamin - I went to http://www.google.com <http://www.google.com> and searched for "utlbstat" and received 1,050 results. I would recommend that you try the same and read up on the resources available over the Internet. I would also recommend the book Oracle Performance Tuning 101 by Gaja Krishna Vaidyanatha Dennis Williams DBA Lifetouch, Inc. [EMAIL PROTECTED]
-----Original Message----- Sent: Friday, April 26, 2002 2:19 PM To: Multiple recipients of list ORACLE-L Dear Gurus , I need your help .. I run UTLBSTAT and then after 2 hour run the UTLESTAT.sql scripts as internal and look at the report.txt generated ... On report.txt , I see that System wide wait events for background processes: System wide wait events for non-background processes : Latch statistics Statistics on no_wait gets of latches Sum IO operations over tablespaces and other things also is in the report. Question 1) What I wonder is Are these values between the start and end times of scripts. What I mean is , for example Is the wait events for non-background processes list in report are the wait events occured between UTLBSTAT script run time T1 and UTLESTAT script run time T2 ? or are they total wait events from the startup of database ? Question 2) I see lots of wait events occur .. What will I give importance to ? will I try to make 0 wait event in report. What are the optimums of wait events. ? For example I see "Latch free event" occured for 3015 times , "control file sequential read" occured for 182 times , "log file sync" occured for 1756 times "direct path read" occured for 11000 times "direct path write" occured for 6000 times Are these values normal ? Will I try to make them 0 in the tomarrows report ? How can I comment on the report ? Is there a link you can tell me to understand the problems and will help me to read and action about the problems ? Thank you... Bunyamin K.
