NAME
nfile — set maximum number of files that can be open simultaneously on the system at any given time
VALUES
Default
((16*(4200+16+maxusers)/10)+32+2*(npty+nstrpty+nstrtel)
Specify an integer value or use an integer formula expression.
DESCRIPTION
nfile
defines the maximum number of files that can be open at any one time,
system-wide.
It is the number of slots in the file descriptor table.
Be generous with this number
because the required memory is minimal,
and not having enough slots restricts system processing capacity.
Related Parameters and System Factors
The value used for
nfile
must be sufficient to serve the number of users and processes
allowed by the combination of
nproc,
maxusers,
npty,
and
nstrpty.
Every process uses at least three file descriptors per process
(standard input, standard output, and standard error).
Every process has two pipes per process (one per side),
each of which requires a pty.
Stream pipes also use streams ptys which are limited by
nstrpty.
WARNINGS
All HP-UX kernel tunable parameters are release specific.
This parameter may be removed or have its meaning changed in
future releases of HP-UX.
