is there any database running on this system like Oracle, if yes how much memory have you allocated to SGA

[vadakkan]

There is no Oracle database running. It is hosting HP OpenView.

Hi,
Check with top command.
or give the below command to check which user/process is taking more memory.

UNIX95=1 ps -e -o vsz,pid,ppid,user,args | sort -rn | head -20

>16GB memory is show 95%
>memory 15554 8964 6590 58%

Were these measured at the same time?

[muruganantham raju]

Hello,
I guess HP Performance Insight uses Oracle DB to store the reports. I am not sure. If Glance is installed in the system, execute glance to find out the process that consumes most of the memory.
Also check the minimum physical and swap memory required by the products installed in your system.
