Summary2: Directory Name cache

• Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] [ attachment ]

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:-

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
