> Project: Synapse

> Components: Core
> Affects Versions: NIGHTLY
> Reporter: Eric Hubert

> Attachments: ServerManager.patch

> Unfortunately I did not find the old issue we had for this, so I created a new one. The provided patch extends the existing server states with a maintenance state. While entering the maintenance mode all transports supporting a pause operation are paused. So no new requests will be accepted. Once all requests in progress are finished the server can be safely restarted to load a changed configuration. If running in a clustered environment behind a loadbalancer this allows dynamic configuration updates.
> All server state changes can be triggered via JMX using an extended ServerManagerMBean which can also be used to query the current server state.
> While working on this patch I thought about moving some of the classes in the synapse top level package to a new server subpackage. I actually did not perform this change to ease the review, but I still think it would be a good idea.
> So what about moving the following classes:
> Axis2SynapseController
> JmxAdapter
> ServerConfigurationInformation
> ServerConfigurationInformationFactory
> ServerContextInformation
> ServerManager
> ServerState
> ServerStateDetectionStrategy
> SynapseController
> SynapseControllerFactory
> SynapseServer
> to
> synapse.server
> and
> ServerManagerView
> ServerManagerViewMBean
> to
> synapse.server.mbean (maybe also renaming them to ServerManagerControl and ServerManagerControlMBean.
