Total OS Memory and CPU Utilisation by database
We have hosted multiple Databases instance on a sigle server. I want to identify the exact of amount of OS Memory and CPU used by each database in pick hrs and in non pick hrs. Is there any script to check this from database?

Re: Total OS Memory and CPU Utilisation by database
1. Version of HP-UX you are running
2. What databases are you running? Are you running different databases such as Informix, Sybase, Oracle, MySql...?
Each database has it's own measurement tools so you'll have to talk to your database administrator about memory usage. Most database systems use shared memory so you'll need the numbers from the database itself. CPU usage is also complex since a database may be part of a number of applications which also consume CPU time.

Re: Total OS Memory and CPU Utilisation by database
Easy
1. Setup application groups in the /var/opt/perf/parm file where you define what processes belong to each application group (database instance).
2. Verify in glance that the application groupings are grouping processes correctly
3. Restarte OVPA (measureware)
4. extract the data from measureware
extract -xp -aA -f /tmp/apps.txt
review the data. or you can view the data with Performance manager.
The metrics will show each group of processes and how much CPU, memory, I/O network and other metrics per aggregated group of processes assuming you created your groups correctly.
