domain on different machines
I’m definitely not
concerned about this for i8. In the longer run since we allow
multiple brokers it would make sense to support having them on multiple machines
since some of the reasons for having multiple brokers (redundancy, load
distribution) are more useful with separate pieces of
hardware.

Bill,
OK … so my questions
stand….
Team,
Any comments?? Is this even a
viable test? If yes, how does the client determine which instance of the Domain
/ Broker to use?
Thanks,
Jimmy

I stand corrected; the domain and broker are packaged together. So as you
stated, there are two sets of domain-broker pairs, one on each
machine.

My interpretation of the setup is that Shivy deployed a single domain in tomcat
on machine 1 and a single broker in tomcat on machine 2. We can confirm this
configuration when she sends the registry (or just ask
her).
The client can be deployed anywhere but it
only knows the EPR of the domain on machine 1.

Bill,
OK cool.. I guess I learnt
something new… In this case, if we have multiple instances of COSMOS running
EACH having the Domain / Broker, what do we do to ensure that only ONE Domain
functions and only ONE Broker function?
Additionally, in this scenario, who
manages the EPRs? The client? And since we have multiple EPRs for a
single component (e.g. we have multiple Brokers), how does the client know which
EPR to use?
Thanks,
Jimmy

Yes I think it’s valid because any COSMOS component (domain, broker, data
managers, UI) may be deployed on any node in the network. The domain knows the
EPR of the broker because Shivy specified the domain EPR in step
3:
3. client app on machine 2; broker register command executed with domain EPR
reflecting machine 1; Broker registered successfully message displayed

Gents,
I have a FUNDAMENTAL question about this defect… Is this even
a valid deployment of COSMOS? If I understand Shivvy right, she was
running TWO different instances of COSMOS… In that case, HOW would instance #1
Management Domain even know about the instance #2 Broker? Or do we have
some sort of an overarching EPR management or registration that can cross
instances????
Thanks,
Jimmy
