RE: process memory utilization
I posted a similar question recently and whilst I received some answers I never did discover an exact way of matching oracle use of memory with unix use of memory. One issue is that when oracle releases memory the unix process does not automatically do the same until the memory is required. Therefore it is likely that there will always be a difference. Tim Gorman pointed me to a script oramem.sh (www.evdbt.com/tools.htm) which does what you are doing with a pmap function which is quite useful The discussion was around 4/10/02 and the thread title was "How much memory is an oracle shadow process using" John -Original Message- Sent: 03 December 2002 11:29 To: Multiple recipients of list ORACLE-L chao_ping, It seems i am posting a too long question, so nobody is interested. I post the answer to my second question, to check the memory utilization in linux operation system. It is in /proc/spid/status file.
