security limits max files that can be open

  • 772

how many files can a server have open?

is it based on the ram/cpu?

/etc/security/limits.conf

*    soft     nproc       65536
*    hard     nproc       65536
*    soft     nofile      65536
*    hard     nofile      65536
root soft     nproc       65536
root hard     nproc       65536
root soft     nofile      65536
root hard     nofile      65536

i used this to increase the limits, but i'm wondering if that number 65536 can be made larger?

Also, does * sfot nproc also cover root soft nproc? or does it need to be spcified for root and *?

    Yes, the nofile can be larger than 65536.

    It's done intentionally since these limits are applied to the user and * can be overridden by setting the username for example on the server running Oracle DB I use\

    oracle soft nofile 104854
