Distribution services are hosted in the first application JVM that is started. They are stopped when this JVM is stopped. In addition, a distribution configuration must be loaded and activated to enable distribution. Deactivating the distribution configuration terminates distribution, even if there is a running application JVM in which they could be hosted. See the section called “Configuration” for details on distribution configuration.

The current distribution status is available on the Distribution Status section of the High Availability tab for a node (see Figure 6.1, “Distribution status”).

	Stopping distribution on an active node causes all high-availability services on the node to be disabled. This causes any partitions active on the node to failover.

Distribution states

Distribution can be in one of the following states:

Table 6.1. Distribution states

State	Description
Stopped	Distribution is stopped either because there are no active application JVMs to host it, or distribution configuration has been deactivated. There is no active connectivity to any remote nodes.
Running	Distribution is active on this node. There is active connectivity to all discovered nodes.

Figure 6.2, “Distribution states” shows the state machine that controls the transitions between the distribution states.
