Re: Admin Servers

The difference with your car though is that about 2 seconds after you start it you can drive off. Or in the case of my hybrids, I'm half way or further up the driveway before the engine even decides to start and if driven recently I can be 1/4 mile away at the stop sign before the ICE is needed. BUT, leave it running and you burn gas doing nothing.

Contrast that to the *ADMIN servers where they take significant effort to start and aren't usable until they are fully going. This can be several minutes on most servers. However once running they take zero resources when they are not being used so leaving them running is a great idea.

Thus they are more like the old 2-Cyl John Deere's I spent so much time on in my youth. Several minutes checking all the fluid levels and looking for leaks or low tires. Then crank up the pony motor and let that smooth out, then hold the compression release as you rolled the diesel over until it had oil pressure, then release that and fire up the diesel. Then of course shut down the pony motor because it was noisy and smokey and only had a 1qt tank. A minimum of 10 knobs, levers, or buttons required to make that thing go from silent to moving! And since it was a diesel it would idle for hours on next to zero fuel so it was left idling a lot if it was to be used again soon. :-)

Well of course if you're using something behind the admin servers you would
leave it running... if it's infrequent you could start them up at that
point and shut them down when done (which a lot of my customers do because
I have to start it often).

It's like saying "should I leave my car running all the time?" The answer
would be no... unless you are going somewhere and using the car. Of course
you would have it running then. But the latter doesn't need to be said.

I agree with Larry.
Not only for administration but also for the general user population.
For those who prefer a web interface over the GUI part of iACS, or for
those functions not in the GUI part of iACS.

Respectfully: Incorrect, or at least partly so, answer.

On a single sever with one partition, certainly incorrect, as you lose
all visibility to peformance, graphing, and any administration functions
that it provides. If you are more than 65 years old this might be OK
mostly, but for younger admins losing the GUI is generally not a good
thing. Some will argue that 'I can do everything needed on a green
screen,' and much you can, it's just harder and you get to see a teeny
window not a huge ass window into your system.

For example, can you look at a joblog for a running job in the green
screen? Sure. Can you search it? No.

Can you display spooled files as a PDF in the green screen? No.

Can you subset active jobs with just a few keystrokes on the green
screen? No.

Can you do ANY performance investigation whatever on the green screen? No.

And certainly the list simply goes on and on and on.

Now, if you have multiple partitions and/or servers then the admin
servers need only be running on one system, as you can manage many
systems from the admin servers running on one system in your data
center. The actual management of the target server is done through the
host servers not through the admin server.
