Kernel parameters

Hi,
I have a little problem tuning kernel parameter on
a digital True 64 4.OF server.
Which is the name of the HP-UX parameter nflocks (file locks)?
I don't found it in kernel.

Thanks, Fabrizio

3.10. nflocks

System-wide maximum number of file locks.

3.10.8. Comparison with other systems

Tru64 takes a slightly different approach to managing file (record) locks than HP-UX. Instead of
allocating a system-wide maximum, Tru64 manages the limit at the per process level by limiting the
number of locks that can be allocated by any given process. The parameter that controls this is
nlock_record. The default value is 10,000, with a min/max of 1,000/100,000.
