2. Re: Dependencies between Modules/MBeans
adrian.brock Oct 30, 2002 10:16 AM (in response to bdbos)It is unclear what you are asking.
What is a module?
What does "running beneath an app server" mean?
If I understand correctly, you have
machine M1 with a jmx service S1
machine M2 with a jmx service S2
You don't want M1 to start S1 until M2 starts S2?
Maybe this is possible with the remoting feature in 4.0?

3. Re: Dependencies between Modules/MBeans
bdbos Oct 30, 2002 11:35 AM (in response to bdbos)Thank you for the response.
Sorry for being unclear...
With a module I mean a subsystem that is represented by a MBean in JMX.
What you describe is exactly what I am looking for:
"If I understand correctly, you have
machine M1 with a jmx service S1
machine M2 with a jmx service S2
You don't want M1 to start S1 until M2 starts S2?"
We have implemented multiple service applications that depend on each other. We are looking for a way to manage this system and handle the startup and shutdown sequence.
Does the JBoss JMX implementation handle depencies between services or is this the responsibility of another part of JBoss?
(I saw the MLet configuration parameter 'depends' in some configuration files.)
What can remoting do for me in the scenario with multiple machines and services?
Thanks,

says don't start this MBean until the other is bean
is started
It is part of jboss-system - the core micro-kernel
built on jboss-jmx
The remoting (just added to the 4.0alpha)
allows MBeans from one server to appear in the local
server and vice-versa.
Thinking about it, it would require a change to
jboss-system's ServiceController to use the remote
mbeans as dependencies, because it does not actually
control them.

bdbos Nov 1, 2002 4:54 AM (in response to bdbos)So I have a job to do. ;-)
Would be a great enhancement of JMX when this would be added to the standard. Am I right? I am pointing to the startup and shutdown of services/mbeans.
Thank you,
