I have been doing some alter sessions to improve performance of gigabyte sized 'minus' operations. How do I tell if this is helping other than completion time?
I believe that if LIOs to PIOs ratio improves with the SAME query then sort_area_size has helped right?(notice Im not trying to improve my cache/hit ratio). I get this from v$sess_io. how do I tell how much temp tablespace my session uses? I cant find a statistic for it? I see that I used up all my PGA since PGA size and PGA max size are equal in v$sesstat. anything else I can look at? -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: <[EMAIL PROTECTED] INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
