OS memory Usage
Hi
Linux DB Server won't show you actual memory, because it reserves large portion of the memory in cache. You can issue "show sga" from sqlprompt to see actual memory utilized by database. However with "free" and "top" command you can check how much memory is free and which process is using what %age of the memory.
However for OS tuning I would prefer to use "sar" (system activity report).
Thanks
