    SGA Free memory dynamics

    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

    Do you flush out SHARED POOL periodically?
