I have an Oracle problem which referes to I was out of "file descriptors".

do anyone know what is the corresponding kernel parameter for "file descriptors" and how to change it?

You need to increase maxfiles and maxfiles_lim which are the soft and hard per process file limits. The system wide limit is nfile but almost certainly doesn't apply in this case.

I have increased maxfiles but the new value never is taken. I have rebooted the server but always say that current is 60 an the value I gave it (100) just say as planned (after reboot).

Â¿Any idea about to change this paramete

How did you change the parameters? What steps did you take? If you just modified /stand/system and did not complete the kernel rebuild process then the values haven't really been changed.

The easiest way to do this is to go through SAM, modify the parameters, let it rebuild the kernel and then reboot.

Hi,
Increase the "maxfiles" and "maxfiles_lim" kernel parameters. Note that maxfiles can not be more than maxfiles_lim.

Hi,

Also check the parameters called:

nfile (which is based on maxusers)
maxusers

They can also be altered to allow more open files.
