Ha, I figured it out (talking to myself seems to help a great deal ;) No
offense I know you are most likely on the other side of the planet and are
probably still asleep while I am writing this)
Anyway... I had a look at the ProxyFactoryHA , and came across this:
| 151 protected void containerIsAboutToStop ()
| 152 {
| 153 if( target != null )
| 154 {
| 155 target.setInvocationsAuthorization
(HATarget.DISABLE_INVOCATIONS);
| 156 target.disable ();
| 157 }
| 158 }
|
After some more asking google for sourcecode I found out that target.disable()
does a
this.partition.getDistributedReplicantManager().remove (this.replicantName);
|
which - it seems to me - removes all replicas (removes it's localReplicant
and propagates the remove operation to all other nodes on the cluster) ...
I take it this is not a bug, but rather the expected behavior for this class ?
As I said I am pretty new to this and could not find much documentation...
anyway.. I discovered eralier that the stop() and destroy() methods of the
ProxyFactoryHA seem to be sufficient to disable the replicant anyway.. so I
simply made a new subclass which does nothing in the containerIsAboutToStop()
method:
| public class CustomProxyFactoryHA extends ProxyFactoryHA {
|
| protected void containerIsAboutToStop() {
| //do nothing
| }
|
| }
|
and updated my jboss-service.xml file:
| <mbean code="at.arsenal.spirit.commons.jndimbean.CustomProxyFactoryHA"
name="jboss.test:service=ProxyFactory,name=HAService,protocol=jrmpha">
| ........
|
.... now everything seems to work absolutely smoothly. Turn off node, switch
node back on... everything behaves as I would expect it to.
Looks like this solved my problem. Or am I missing something else which I could
have broken with this patch? :-)
