I know this has been discussed before and I have monitored the discussions but I am not sure that I have seen a clear summary and set of conclusions.
I am trying to identify how much memory is used by the instance and all connections. I can show sga to give a total memory of the base instance /usr/sbin/pmap -x pid gives a rather verbose output and I struggle to work out exactly which of the lines is the one I am most interested in I have also tried ps -eo vsz,pid |grep 5225 where 5225 is the pid of an oracle connection and that returns a value that includes the SGA and also bigger than the return from the sql script below I run the following script to show me how much pga memory has been used for each process select name,sid,value/1024/1024 "Curr Mb" from v$sesstat a, v$database c where statistic# = 20 # shows current session PGA However I am convinced that that query is not accurate as it seems to return some very small values on systems that are quite busy. Also statistic# =21 which is the maximum for each process does not vary much from current which disturbs me a little as we have a lot of constant connections Has anybody got a easier/more accurate method of determing memory usage Thanks in anticipation John -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: 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).
