make kernel

[UniRock]

Hi all,
Kindly tell me the procedure of building a new kernel (while changing nfile value) and then set it as a permanent.

My server is 11.23/rx2600.

Thanks in Advance.

kctune nfile=value

You don't need to build a new kernel in 11.23.

Just kctune nfile=

It will hold across reboots by default, and since it is a dynamic tunable (man 5 nfile or see http://docs.hp.com/en/B3921-60631/nfile.5.html ) your change will take place immediately.

Note that (as stated in the man page) if you're actually lowering it from the computed default in the kernel such that it is lower than the actual number of open files, the operation can be failed. It must also be equal to or greater than two times the value of maxfiles_lim. [Anyway -- see the man page for all this].
