How much Oracle process & session in relation to physical RAM?

edited Feb 24, 2020 2:57AM in Database Administration (MOSC) 4 commentsAnswered

Can anyone advice, when setting up the number of sessions parameter, what are the things I should consider?

As I understand each session is a connection in the database & each of the sessions has a certain amount of virtual memory allocated to it.

Based on what I can see from my environment, a 24core CPU & 64GB RAM server. The memory max target is set to 12GB with memory target 11GB.

I notice that each of the OS processes from Oracle are allocated a virtual memory of 12GB

Currently the maximum sessions set to this server is 2000, is this an overkill? Will it cause excessive swapping?

Howdy, Stranger!
