setting # of processes

[learn]

How do I determine/calculate the right number of processes that I should set in my initSID.ora parameter?

Hi,

The Processes parameter specifies the maximum number of O/S user processes that can simultaneously connect to the database. This includes all the background processes. Therefore the processes parameter should be the sum of the maximum number of users and the number of background processes running.

Each user can have more than one connection, process. So it cannnot be max users + system processes.
What do you think ?

identify average number of connections that shall be open by your application (if client-server) and multiply the number of users and add the number of background process.
