Greetings,
We currently have a limited deployment of Sun Ray 2FSs, are looking to roll
out Sun Ray 2s (and maybe 2FSs) throughout a medium sized control-room type
environment.
We wish to implement multiple small two tier solution, a server running the
software and the SRSS to a small group of directly connected DTUs. Due to the
control-nature of the environment, each of these units (just described, server
+ DTUs) should be completely stand-alone, and not require or ideally know about
any other unit on the network.
Now to the group manager, it multicasts or broadcasts over the network to
find all the Sun Ray Servers; which we do not want or need. No problem, reading
auth.props I find enableGroupManager and set it to false and utrestart. No
Problems. DTUs are fine and everything looks OK, utgstatus can no longer
reports status as it can't talk to the group manager, but all is well. Later
I'm looking at the new Web UI and notice that the servers and other pages
reports errors and has I few minor issues. This leads to reading the auth.props
manual page and discovering that changing enableGroupManager is UNSUPPORTED.
My question: Is there actually a supported way to install, configure and run
the Sun Ray Server Software, such that multiple single-server solutions do not
and can not communicate with each other or have knowledge of each other?
Changing enableMulticast is unsupported, and still leaves broadcast enabled.
I have considered leaving the standard configuration in place and giving each
system a unique gmSignature, but is this really the right approach? We just
don't want the failover or load-balancing functionality, and will happily live
without the Web UI. Also it a highly automated environment (based on Solaris
Jumpstart etc etc), we'd like each unit to re-use the same private subnet
number system; given the purpose of group manager includes determining
connectivity it seems like it would be undesirable to even have it running.
Does anyone have any thoughts on disabling the group manager or appropriate
ways to configure the described architecture?
Many Thanks in Advance,
Peter
PS: We are running Sun Ray Software 4 09/07 (fully patched) on both SPARC and
x86_64 boxes running Solaris 10 Update 4 and Solaris 10 Update 5.
