Subject [jira] [Created] (QPID-5885) Virtualhostnode to replace real virtualhost with replica virtualhost in the event that the BDB HA goes into detached state

             Summary: Virtualhostnode to replace real virtualhost with replica virtualhost
in the event that the BDB HA goes into detached state
                 Key: QPID-5885
                 URL: https://issues.apache.org/jira/browse/QPID-5885
             Project: Qpid
          Issue Type: Bug
          Components: Java Broker
            Reporter: Keith Wall
             Fix For: 0.29


Currently, if the BDB HA node goes into a detached state (as it does when it restarts itself
when it detects that quorum has gone), the virtualhost remains available.  

If a client attempts a virtualhost operation whilst the node is in this state, the operation
appears hangs with timeouts appearing on the client.  This hang is owing to the ReplicaConsistencyPolicy
- which defaults to 1h.

The virtualhostnode should replace the real virtualhost with the 'replica' virtualhost when
the node is in detached state.  This will cause existing client connections to be disconnected
and new connections will be disallowed.
