Hello all,
If a server is running multiple databases (ranges from 8.1.7.4 to 10.2). Is
there a way to estimate the CPU capacity that are used by each of the database
which will relate to the OS system load?
We do have AWR (tuning/diagnostic packs) for 10.2 databases, but we may have to
rely on other methods for 8i databases.
I'm trying to arrive at something like this:
Database-1 = 30%
Database-2 = 20%
Database-3 = 10%
Database-4 = 40%
The hardware platform is Sun Sparc Solaris 9.
I'm trying to relocate a few databases to newer platform. With the move I'd
like to recoup some of the Oracle licenses by reducing CPU capacity (turning
the CPUs off or physically pull them out ) on the legacy servers.
Your suggestions are greatly appreciated.
Thanks
-Upendra
