Hi,
I was present at Edson Tirelli presentation at Just Java 2007 in Brazil
and got impressed about drools and brms.
I'm implementing a mission critical application using drools+brms and
have some doubts that didn't find answers in the manuals or searching
the mailist archive.
We need the cluster servers both running drools and specially getting
updates 24x7. I chose to use the RulesAgents and BRMS in order to have
dedicated servers to build the rules packages. I think that's the best
solution instead of implementing the administration and synchronization
from scratch, right ?
Configured JCR to use a oracle database for the rules repository. Can I
have a administration cluster with two or more servers running BRMS
(drools-jbrms.war) pointing to the same database ?
Is it cluster aware ? It would be necessary to configure the rule agent
to point to 2 url's snapshots for the same package. I think it's a
problem... If not, what would be the behavior ?
Another solution for clustering the brms I thought was to have a http
server or hardware pointing to a primary brms server. In case of failure
it switches to the stand by brms server. But I think the updates on the
primary brms would not be reflected on the stand by server, right ?
Is it possible to have the rule agent dynamically configured to point
the a new snapshot url instead of statically configuring the urls on the
properties file used by the rule agent ?
The brms manual says that it possÃble to replace the GWT interface,
connecting directly to the RepositoryService (ServiceImplementation). I
saw that the ajax communicates with the GWTRemoteServiceServlet on the
server side. We don't need to replace the interface, but need a remote
interface in order to have one external system make calls to the
RepositoryService. Is there any other remote interface like web service
or remote ejb ? If not, what is the fastest solution to make remote calls ?
Thanks in advance,
Wesley.
