I am at 9204 and I was experiencing ora-4031. That's why I started watching the free memory. thank you Gene Gurevich "Hameed, Amir" <Amir.Hameed@xero x.com> To <genegurevich@xxxxxxxxxxxxxxxxxxxxx 02/08/2006 11:38 >, <oracle-l@xxxxxxxxxxxxx> AM cc Subject RE: SGA Free memory This is normal behavior as chunks are flushed from and added to the shared pool, the memory fluctuates. As long as you are not seeing ORA-04031 error or contention on the shared pool latch is not too high, you are fine. What RDBMS version are you on? -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of genegurevich@xxxxxxxxxxxxxxxxxxxxx Sent: Wednesday, February 08, 2006 12:28 PM To: oracle-l@xxxxxxxxxxxxx Subject: Re: SGA Free memory Hi all: I am watching the usage of the SGA on my database via the following command: select to_char(sysdate,'mm-dd-yyyy hh24:mi:ss'), name, bytes/(1024*1024) from v$sgastat, dual where pool like '%shared%' and name = 'free memory' order by bytes asc ; I am running it every 10 seconds. Recently I saw the free memory going from 25M to 145M over the course of 10 sec. I'm wondering what could have caused it. Would appreciate any suggestions thank you Gene Gurevich Oracle Engineering 224-405-4079 -- //www.freelists.org/webpage/oracle-l -- //www.freelists.org/webpage/oracle-l
