[Casper] 10.4 vs 10.5 server for test environment

Thu Feb 19 11:22:16 PST 2009

Even though my previous email about this said it was indeed very much
possible to do so, and you could even have different clients checking
into the different instances of the JSS, but I would have to agree with
Miles, this is probably not recommended.   

Unless perhaps you split the load between two separate JSS servers, then
had all your VLANs chopped up and pointed one network segment to one JSS
and other segment to the other JSS.  Then all you have to do is edit the
/etc/jamf.conf file on the client to point to the right server.   

My new xserve though handles about 6,000+ clients checking in every 15
minutes just fine for the most part.  My database is chunky and tends to
need some maintenance from time to time but for the most part one server
handles it OK.  We then have building level distribution points which
helps also.

It is absolutely possible to run multiple JSSes on the same box.  I'm
almost absolutely sure this isn't supported, and I agree wholeheartedly
with Craig that such experimentation shouldn't be done on production
boxes. 

I would recommend picking up VMWare and running your test box(es) on a
VM.  What I've done is spec out two beefy Xserves and installed VMWare
on them for my testing environment.  This should be more cost effective
than purchasing and maintaining a bunch of low to mid-range boxes and
certainly less headaches than scrounging old hardware (which I've found
to be PPC these days, and most of the stuff I want to test requires
Intel). 

If you are a Developer Connection member, you can download install media
for Tiger, Leopard and prerelease Snow Leopard builds (of course you'd
be under an Apple NDA, as I am, so don't ask me about Snow Leopard. 
Sign up and find out for yourself). and a serial number that's good for
a few months, which should be long enough to get through any testing.

The issue is the name of the database and how the components connect to
it. The database is jamfsoftware, you need to be able to change
everything that points to that to a second database with a different
name.

I personally would never want to mix test and production on the same box
regardless of whether or not it's possible, with the exception of if the
second instance was virtualized.

What would happen if you create 2 domain entries with different ip's 
hosted them on the same server, 

youd have jss1.mydomain.com and jss2.mydomain.com and have two different
ip's resolving via your dns 

Then using the JSS Setup utility connected to jss1 and installed the JSS
and then conencted to jss2 and installed a second JSS 

Both would be hosted on your server via the same NIC but have different
databases under different domains and ip's ????

 My test environment is a G5 tower running Tiger Server. Works great. I
attempted to use Parallels server for my test environment Leopard
server, but performance was an issue for some reaI don't think it's convenient or even easy/possible to run a second
instance of the JSS on the same system without some heavy modification.

 Hi-

I'm going to be setting up a test environment on a second xserve. 
Basically, another JSS.  2 questions about this:

The hardware I have available has 10.4 server on it.  Is there that much
of a difference, that I should go with the cost of upgrading to 10.5 on
that box when it comes to the JSS?               

Related, if there is a big enough difference, instead of purchasing
another copy of 10.5 server, is there a way to set up a second instance
of the JSS (the test JSS) on the same box as my prod JSS?  Related note,
my NICs are teamed.  I know this is likely not recommended, but I'm
curious anyway. 

 Thanks
