[ILUG] max open files

[Michael Hinds]

Hi,

I just gave myself a heart attack when I tried to run a script on a
production server (RH6.1, Oracle, lots of web servers) and bounced off the
max open files limit.

Can I just echo a new value to /proc/sys/fs/file-max and
/proc/sys/fs/inode-max on the fly without any of my apps dying on me? I'm
particularly nervous about Oracle, because when she goes, she doesn't just
fall over, she explodes!

Also, does anyone know any different to the inode-max = 3x file-max rule?

Ta,

Michael
