2: Directory Name cache

2007-12-25 11:23:00

Here's some more info I received after I posted my summary.

Change these parameters in /etc/system:-

set ncsize = 15000

set ufs_ninode= 30000

set bufhwm = 10000

Chnages take effect on next reboot.

Word of warning make a backup of /etc/system first and if it doesn't boot

properly you can boot with the '-a <old-system-file>' and try again.

There are other things you might want to tweak as well. To see what the

dnlc rate is, try the following:

vmstat -s

This will produce a lot of data that you might be interesting

My original question:-

I'm getting the following message on my Sparc station running Solaris

2.5:-

Adrian detected Directory Name cache problem (amber)

Poor DNLC hitrate, increase ncsize

DNLC 78.3%, reference rate 218.48/s

DNLC has 144 entries, try increasing it (and inode cache) to 2288

How do I increase ncsize etc. Sorry for my ignorance but I am new to sun

unix
