CPU Caging for a database running in a server with multiple instances

edited Sep 16, 2015 10:10AM in Database Administration (MOSC) 2 commentsAnswered

Hi guys,

I'm facing a critical issue!

we have a server with 8 CPUs.

20 Instances are running on this server, all of them are 11.2.0.4.

-----

the problem that there 2 online DBs (Hot DBs), which are connected directly to some websites.

I know that I can use cpu caging in resource manager, to cage a db to use some CPUs.

in my case! how could I prevent all other 18 Instances to user only 3 CPUs, and let the 5 CPUs always free/available for the BOTH HOT DBs.

CASE 1:

if I used cpu caging to limit all other 18 DBs to user only 3 CPUs, how could I ensure that all of this 18 DBs are using the SAME 3 CPUs.

Howdy, Stranger!
