Functions of these Kernel parameters?

[Cem Tugrul]

Hi forum,
i have RP2450 9000/800/SD16000 and B.11.11 hp-ux with BaaNIV erp &Oracle 9.2.0
When i run glance -t ;

System Table Available Used Utilization High(%)
--------------------------------------------------------------------------------
Proc Table (nproc) 6404 865 14 14
File Table (nfile) 32778 11152 34 34
Shared Mem Table (shmmni) 200 12 6 6
Message Table (msgmni) 8192 2 0 0
Semaphore Table (semmni) 6400 36 1 1
File Locks (nflocks) 6404 222 3 3
Pseudo Terminals (npty) 300 0 0 0
Buffer Headers (nbuf) na 119238 na na

As you seen my kernel parameters value seems set more than Oracle9i recommeds...

Now i want to know what do these parameters for?Are they important for my sys performance?Do i have to change them?i sometimes monitor %100 Disk Utilization via Glance so Do these parameters effect?i really want to know functionalities about these parameters;
nproc,nfile,shmmni,msgmni,semmni,semmni,npty,
nbuf

Regarding you 100% disk utilization in glance, i could be wrong but i dont think it affects the disk utilization.

Check which disk is having a bottleneck. We have the same issue and what we did is we relocated busiest datafiles to different disk to balance the I/0/
