Well, see the code I sent under separate cover, but here's how i think you
can get exactly the same code execution sequence:
[ClusterPartition created, configured, but not started]
HAJNDI created, start does nothing
(other needed mbeans also created and started similarly)
Now the dependencies

Hi Geeks
I don't think the mbean-ref list will WORK. As you said the ClusterPartition
will be created, attributes are set BUT it won't be started.
AFAIK ClusterPartition needs to initialize JChannel before the other HA-
service can start, doesn't it? Yeah, but then this initialization is NOT
STA

Does this mean that the dependencies can go like this?
JBOSS-SYSTEM:service=DefaultPartition
JBOSS-SYSTEM:service=DefaultPartition
rather than like this:
JBOSS-SYSTEM:service=HASessionState
JBOSS-SYSTEM:service=HAJNDI

Yes, it is possible.
Next step on my todo list is to speak
I'm happy to try to fix this problem along these lines, especially if
someone will tell me which mbeans need to be synchronized(?right word?)
1. in ClusterPartition, include
JBossCluster:service=HANaming

Hi Bill
I don't think this works. When you use dependencies feature just wait until
the MBean is available. But when your services is deployed on another thread
then the init() and start() sequence runs out of order and you can fail.
Only when
all the services are deployed by the same thread (Dep

You will not see the problems introduced by removing init unless you setup
HA-JNDI on one node, bind a bunch of stuff, then bring up a second node.
The second node will not get state-transfer from the first if you have
removed init. Again. This clustering stuff needs a 2 stage startup. Please

I'm trying to eliminate init and destroy because they were getting called
like this from ServiceController:
init();
start();
and
stop();
destroy();
. If there are problems left after combining init and start, or if you
would like me to do this, let me know. Is there any way to test the

Yes this a very serious problem and it wouldn't show up with your Farm

In the init phase, all services register with the cluster (HAPartition) for
cluster events that want to listen to and a
Hi Bill
I added all the code from init() into start(). Is this a problem ?
At least when I use the Farm it works like a charm.

Guys,
The clustering stuff is dependent on init and start both being there. Can
we put back the init? Otherwise you break our stuff. Why are you doing
this anyways?

Thanks, must have missed that one.
I generally copied the init[Service] code and put it in start[Service] at
the beginning, similarly for destroy.
As far as I could tell, everything covered by the testsuite works as well
after the changes as before.
Please let me know of other problems.
