What is ulimit and what it does?
 

Hello All!!

Always I'm gonna do a new installation of an Oracle product
I have to set the ulimit value, but actually I don't know exactly why I must set it and what it does. I've looking for information about that but all I could find was some documentations explaining how to manage it, I'd like to know the concept behind it. Does anybody can give us a brief explanation of ulimit??

Thank you!!

its the maximum amount of processing a user is permitted to have running at the same time

The ulimit is a mechanism for restrict the amount of various resources a process an consume. There's a shell command to set the ulimit for processes which are started in that shell.

If you are using bash as your shell, you can list the current ulimit settings by issuing this command in a terminal:
