Oracle Memory issues

Oracle Memory issues

Oracle Memory issues

(OP)
Hello,

Is it the case that Oracle Processes will take up as much RAM as possible? It seems everytime that Oracle Processes take up all the available RAM in our Production System. So everytime we add more RAM, it takes more up. Is this normal?

We are running AIX 5.3 ML04 w/ Oracle 10g Server. We have mounted the /oradata directory w/ the CIO option which bypasses the file buffer area in memory to help out a bit.

I thought the SGA and PGA areas were supposed to limit Oracle's usage of RAM or at least cap it to a certain point.

Whenever I see what's occupying RAM using 'svmon -P', it's all Oracle Processes.

What are other ORACLE/Unix shops doing to control RAM usage? How much physical RAM do you have in your servers? and how much does Oracle take up?

Thanks!
