Who or what requires DMI?

[Ralph Grothe]

Hello,

I wonder which vital service would require the so called Desktop Management Interface?
We don't use any X or desktop manager like CDE or similar, although for strange reasons the dtlogin is started anyway at boot up.

On one box I have a cpu hogging DMI service provider process (until now haven't even known such beast existed).

# UNIX95= ps -C dmisp -o user,pid,ppid,stime,time,pcpu,vsz,pri,nice,flags,arg>
USER PID PPID STIME TIME %CPU VSZ PRI NI F COMMAND
root 1265 1 Aug 16 3-22:05:30 100.22 2732 152 20 1 /usr/dmi/bin/
dmisp

Note, the STIME here is a bit misleading because this box has an uptime of 368 days which happens to date back to last year's 16th Aug.

I searched knowledgebase and came accross this recipe where they suggest to set up a cronjob that would restart DMI every now and then.

http://www8.itrc.hp.com/service/cki/docDisplay.do?docLocale=en&docId=ucr_na-KMN8606352541_ssb-1

But because to my knowledge no one seems to require DMI I rather would prefer to kill the thing and set this to 0:

# grep ^START /etc/rc.config.d/Dmiconfig
START_DMI=1

Would I detrimentally affect any other vital service by doing so?

Regards

Ralph

Hi Luk,

the first link you provided is much more recent than what I have found in KB.
According to this doc I now need to find out whether we are using SCM or SIM.

Independent of whether I decided to stick with DMI,
I already restarted DMI and the cpu usage of dmisp for now has dropped to abt. 5%.
Guess this box has been running too long without a reboot, which reminds me of that it is high time for a dose of current Support+ patches here.
Chances are there's one patch within the bundle that even already has fixed this issue.
