“Max open files” for working process

Question

Is it possible to increase \"Max open files\" parameter for working process ? I mean this parameter:

cat /proc//limits | grep files

Answer 1

This link details how to change this system wide or per user.

Many application such as Oracle database or Apache web server needs this range quite higher. So you can increase the maximum number of open files by setting a new value in kernel variable /proc/sys/fs/file-max as follows (login as the root):

$ sysctl -w fs.file-max=100000

You need to edit /etc/sysctl.conf file and put following line so that after reboot the setting will remain as it is
