Operating a dynamic topology

Introduction

When a topology is declared as dynamic, several operating tasks can be done to modify the topology:

  • move a running container from a sub-domain to another sub-domain,
  • detach a running container from its current sub-domain.

Detaching a container

Any container member of a dynamic sub-domain can be hot-detached at any moment. After detachment, the container is running in a dedicated standalone topology, ie. in a dedicated sub-domain of a dedicated domain.

The detachment is realized through the JMX API of the container to detach using the method 'detachContainer' of the MBean 'Topology'.
After the detachment, the endpoints of the container are no more available in the initial topology. They are moved in the new one.
