Re: [cosmos-dev] i9 QA - Testing with multiple Data Brokers
|
Both the domain and broker are put in
the same war file for several reasons:
1. We only claim to support a single
broker in this release, so it's better to make the domain vs. broker distinction
more transparent. With only one broker, the domain really has no
practical importance.
2. Smaller footprint: Both domain and
broker actually share the same implementation. They are both service
groups. Packaging domain and broker separately would mean duplicating
the code. It's just a matter of changing a configuration file to
add or remove a service group.
3. Ease of deployment: Having
one fewer web app to worry about will arguably make the demo simpler.
Having said that, the currently implementation
does support the multiple broker scenario. You can deploy the cosmos.war
on several servers, and assign one of them the role of the management domain.
On a sever where you just want to assume the role a broker, or the
management domain (i.e. not both), update the muse.xml file to remove the
corresonding resource-type section. (I have not documented this feature.)
It was a deliberate design decision
to support a two-level address lookup architecture, and not to claim support
for multiple brokers. I would defer to Mark, Don and Jimmy to confirm
this decision. The test plan should reflect our support statement.
At the moment, I don't see the need to have two separate war files for
the domain and broker.

Data Brokers |
|
Team,
As you know, in COSMOS 1.0, till date, we
have been proceeding with the one Management Domain and one Broker model.
Having multiple instances / types of Brokers
is something we deferred to a later release.
That said, do you think QA should still test
the situation where there is ONE Management Domain and MULTIPLE instances
of Data Brokers? What would the value be of such a test at this point?
If you feel this is a good thing to do in
i9, do we need to open an ER to put the Domain and Broker in different
bundles?
Thanks,
Jimmy Mohsin

Query from Srinivas Doma
1. Single
cosmos.war
(domain and broker) bundle
-
Currently we have domain and broker under
single bundle? Can
we have them in different bundles, so that
we
can
configure
one domain and multiple brokers (either
on same machine or on different machines)
