Increasing the maximum number of concurrently open files beyond 1024 on Ubuntu.

On Ubuntu 18.04, the maximum number of concurrent open files is 1024.

But we need to reset this value to 65535 permanently and as a global setting. Most documents describe how to set this value temporarily and per process.

Can anyone describe how to do this?

Thank you

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

In system.conf

Add (after [Manager]):
DefaultLimitNOFILE = 65536
