Disabling Services in Solaris

romeo_tango · 04-29-2008, 11:44 PM

i have 2 box running Sun OS 5.10 and when i enter prstat -a command, the root users will have > 90 to 100 services on it.. so i list it using prstat -U0 (its zero for root UID) and here is the list :

Code:

   PID USERNAME  SIZE   RSS STATE  PRI NICE      TIME  CPU PROCESS/NLWP
 18573 root      194M  130M run     59    0   2:10:41 0.3% java/23

Total: 107 processes, 441 lwps, load averages: 28.95, 23.18, 24.71

well, I already check a few of them but still there are many i can't find the manual / description in the google. so could somebody help me...

what are these services and can I disable them?
- limstrerr
- wvCmdInvoker
- fmd
- fjsvdrd
- evmond
- evhandsd

in my other box, there is this process

Code:

1 root     2384K 1424K sleep   59    0   6:01:44 0.2% init/1

What is the init doing there listed?

Is it normal if the root user running hundreds process or more?

Last question is can i disable the gnome-panel or its X desktop while the server still running without restarting the server ?

Thanks.

Don't confuse services, daemons and processes.

"svcs -p" will display all the services and the corresponding processes.

Most of these processes you are using almost no RAM / CPU so why do you want to disable them ?

init is the parent of all other processes under Unix. (man init)

I'm not sure about what you want to do with gnome-panel, which is part of the graphic environment. You can disable the whole JDS/X11 thing and fallback to a text only console.

That just means init is more active on that machine, no big deal.

Sure:

Code:

/usr/dt/bin/dtconfig -d
/usr/dt/bin/dtconfig -kill

or

Code:

svcadm disable cde-login
