Hi
I'm in the process of decreasing oracle processes memory on hp-ux 11i v3. All oracle processes are consuming more than 120MB. vmstat shows free memory less than 100 sometimes.
Is it possible to decrease the processes size by setting new value for virtual page memory for oracle executable by issuing the following cmd,
# /usr/bin/chatr $ORACLE_HOME/bin/oracle
How to interpret the below results from the above cmd,
segments:
index type address flags size
8 text 4000000000000000 z---c- 16M
9 data 6000000000000000 ---m-- L (largest possible)
executable from stack: D (default)
Thanks.

You are wasing your time & effort.
With any thing you do the results will be similar to those above.
Trust me.
It is simply how Oracle & Unix interact.
Besides "free memory" is memory which is not used by OS & not used by applications. Why do you think memory unused & idle is to be desired. It simply is wasted RAM.
Don't you want to use as much RAM as possible?
