Increase no of files ?

**titusabraham** · 10-03-2009

I am analyzing a dump file for which i need a large no of files to be open at a time such as around 50000 files. the fedora OS i am using allows me to open only 1024 files which made sense as in ulimit -n i can see no as 1024 and i modified ulimit from /etc/initscript to a very large no but i can now open only a max of 5651 files. Any suggestions ? i am stuck in my research project due to this.,

try adding this to /etc/security/limits.conf

Code:

* - nofile 65536

add this to /etc/sysctl.conf

Code:

fs.file-max = 65536

then issue command as root

Code:

sysctl -p

then log out and log back in

I'm not sure what it is, but I've seen people with values at 500,000 or so from some quick googling.
