System Startup

Pete Randall — Fri, 16 Aug 2002 13:57:04 GMT

Why is opcagt started during startup when
the config file says the default is no and I
don't even have
OpC/ITO/whateverit'scalledthisweek?
This happens in both 11.0 and 11i.

Hello,

You can check two files:
/etc/rc.config.d/opcagt - edit and make sure you disabled all processes.
/sbin/init.d/opcagt - move or rename this if not needed.

Sajid,

Trust me, I've checked them. The comments in the config file say the default is no, yet the parameter is set to 1 (yes). I'm wondering why there is this discrepancy and whether there is any harm in turning it off.

Does the start-script has the line: . /etc/rc.config ?

The /etc/rc.config reads all /etc/rc.config.d/ for all the variables.. is the variable 'no' or '0'.... you say 'no', but it should be 0.

Look at this example:
VAR=no
if [ $VAR ]
then print Starting
else print No-start
fi

The result is: 'Starting', although $VAR equals 'no'.
Solution: VAR=0

If this isn't the case, please tell us.

Ceesjan

Pete,

HP built me a new rp5450 and a new rp7400. By default, the OpC is on. Since my systems have nothing to do with OpenView, I turned them off. I noticed that it did no harm to the system but it takes lots of time to initialize at bootup.

Ceesjan,

The variable is set to 1 - my question is why? and what am I going to mess up by setting it to 0.

Hai,

That's what I was looking for - it sounds like I can turn it off with no ill effects. I'm going to hold up on your points for a bit, but you'll get them, don't worry.

Likely, you have some other OpenView modules installed:
1. Omniback (omni)
2. Perfview (pv)
3. Measureware (mwa)
4. IT/O agent (opcagt)
5. Openview (ov300|ov500)
These modules are related to each other. Even a simple Glance (like Perview) belongs to the package.
If you will shutdown opcagt, the parts 4,5 will not work. If you have installed Measureware later, it can trigger the start of the related module IT/O.
Omniback and Perfview will work just fine without opcagt.
Assuming you do not use ITO intensivly, just turn opcagt off.

Ceesjan

Hi Pete,

Just curious, is opcagt being on causing an issue with your system or performance?
Or is this more of a curiousity issue?

If it's curiousity, I'd be more inclined to just leave it on until it can be researched rather than risk possible problems.

Kel
(I'm curious tho' so I'll research a bit myself, time permitting.)

Re: System Startup

Pete Randall — Fri, 16 Aug 2002 14:30:55 GMT

Ceesjan,

Thanks, that's what I was looking for. I've got GlancePlus and Omniback and didn't want to mess up any of the other OpenView stuff trying to get rid of the opcagt.

Bunnies are forthcoming.

Kelli,

It's a curiosity that's been bugging me for better than a year - I'm leaving it on while I'm doing this research. Stay tuned.

Pete,

I am curious. What do you get when you type "/opt/OV/bin/OpC/opctemplate"?

Are you using ITO?

Re: System Startup

Pete Randall — Fri, 16 Aug 2002 15:08:34 GMT

Marty,

"and I
don't even have
OpC/ITO/whateverit'scalledthisweek?"

so what I get when I type that in is "not found"

Pete

Re: System Startup

Martin Johnson — Fri, 16 Aug 2002 15:19:16 GMT

You can turn it off. The agent isn't doing anything and you are just wasting time during startup.

Marty,

My sentiments exactly.

Pete

Re: System Startup

Martin Johnson — Fri, 16 Aug 2002 15:30:10 GMT

Curious: What kind of messages are you getting in /etc/rc.log?

Marty

Re: System Startup

Pete Randall — Fri, 16 Aug 2002 15:31:48 GMT

Marty,

Starting OpC agent processes (opcagt).
Output from "/sbin/rc3.d/S941opcagt start":
----------------------------
OpC Agent processes successfully started.

Re: System Startup

Martin Johnson — Fri, 16 Aug 2002 15:33:50 GMT

Hmmm. I would have thought you would get an error message since ITO is not installed. Does "ps -ef | grep opc" give anything?

Marty

Re: System Startup

Pete Randall — Fri, 16 Aug 2002 15:36:03 GMT

Marty,

psg opc

It's obviously starting some stuff.

Hi Pete
On my systems also by defauls it was on and alway runing. Since we do not use OV here, I turned it of. set "OPCAGT=0"
in /etc/rc.config.d/opcagt file.
If you do not care of using openview agents to comminucate to ITO or any other monitoring software, you may turn it off.

Thanks.
Prashant.

And, before you ask, swlist shows:
