Hi guys,

I'm trying to change 'maxfiles_lim' kernel parameter on HP-UX 11.31 to a new value as prerequisit for oracle application installation release 12 (12.0.4)for HP-UX Itanium :

maxfiles_lim 4096 Default value
maxfiles_lim 65536 New value (as Oracle Required)

but always i have this problem:
ERROR: The proposed values for nfile (30000) and maxfiles_lim
(65536)do not meet the constraint of (nfile >= (2 *
maxfiles_lim)).
Command Unsuccessful

but as u know guys nfile is Obsolete on HP-UX 11.31,and it's now private and deprecated...:(

so could you please help me in this issue ?how i can change maxfiles_lim to this value 65536?

Hi

Note please maxfiles <= maxfiles_lim << nfile

Nfiles is obsolete but not unconsiderable.

Show the kernel parameters what is the value of nfile.

maxfiles_lim values must be lower than nfile.

Why do you need maxfiles_lim this big?

>i'm trying to see the nfile value but unfortunately i can't find it but the value proposed to be (30000)

I assume you can use kctune to change the value of nfile to 128K, then you can change maxfiles_lim.

Hi Dennis,

thanx for your help,everything seems to be OK now.....:)

i have changed nfile parameter to the Default value which is 0,it was 30000 before,after that i could change the tunable maxfiles_lim to the 65536

thanx

i have changed nfile parameter to the Default value which is 0 (by using kctune command),it was 30000 before,after that i could change the tunable maxfiles_lim to the 65536
