[Design of JBoss Portal] - Re: Initiall identity model discussion

I know about Portal's AS agnostic intentions. JBoss Security is just an SPI and an implementation. There is nothing that is AS dependent. It should be geared to run in a MC. It does not even require JMX.

[Design the new POJO MicroContainer] - Re: InstanceClassFactory extension to the ManagedObjectFacto

by scott.stark＠jboss.org

I thought about just adding more annotation support to the service mbean metadata, but that is more error prone for a deployer writer who is programatically creating the mbean metadata. It would not be a big deal for those still using the legacy service.xml. In terms of the InstanceClassFactory being part of the spi, maybe this should be pushed to the AbstractManagedObjectFactory as an implementation detail for this release.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Handling cluster state when network partitions occur

by galder.zamarreno＠jboss.com

Yeah, you're right on that. There's no guarantee that such independent arbiter would be available too. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4079673#4079673 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4079673

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Handling cluster state when network partitions occur

by bela＠jboss.com

How do these tool determine whether we have a partition, or whether some members just crashed ? Nothing different from what we want to do: they need a deterministic decision, e.g. through an independent arbiter: shared file system, DB, or separate network, or through majority decision as discussed before. In other words, those tools won't solve the problem for us, either.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Handling cluster state when network partitions occur

by galder.zamarreno＠jboss.com

It'd be cool if JGroups could hook into network monitoring tools and be able to be notified of network partitions or cluster split situations.

[Design of Clustering on JBoss (Clusters/JBoss)] - Re: Handling cluster state when network partitions occur

by bela＠jboss.com

You're right, so it looks like the only solution here is to shtu down that node and fail over clients View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4079623#4079623 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4079623

"bela(a)jboss.com" wrote : (3) Another solution rather than shutting down is to cease caching values and pass all requests directly on to the underlying DB. Of course, this makes only sense if we *have* a DB, otherwise shutting down is probably our own option This would need to happen on all partitions, though, otherwise you have the problem of the minor partitions updating the database, and the primary partition then reading stale data from it's cache. Ceasing caching on all partitions is a problem though, as it's not clear how the primary partition distinguishes the cluster split from normal operation.

[Design of POJO Server] - Re: ServiceController unregistering

by alesj

What about if you just moved ServiceController uninstall to | public void preDeregister() | throws Exception | { | // Shutdown ourselves | controller.uninstall(ServiceControllerMBean.OBJECT_NAME.getCanonicalName()); | } | and reinstate the unregistration from MBeanServer in JMXKernel.
