First figure out which ulimit you are seeing.

Right now I can set it for a session but I want it set permanently. Thanks for help. When I say ulimit it says unlimited but when I do ulimit -a I see some values that are not unlimited. I think unlimited is also limited by the settings on the server and is not really unlimited. Thanks
