Figure C.1: Resource Adaptor Entity lifecycle state machine

Each state in the lifecycle state machine is discussed below, as are the transitions between these states.

C.2.1 Inactive State

When the resource adaptor entity is created (through use of the Resource Management MBean) it is in the Inactive state.

When a resource adaptor entity is in the Inactive state it may not attempt to provide Rhino with events for processing. If it does

so Rhino will discard the events and inform the resource adaptor entity that the events have been discarded. A resource adaptor

entity may be removed when in the Inactive state.

• Inactive to Activated transition: This transition occurs when the

activateEntity

method is invoked on the Resource

Management MBean.

C.2.2 Activated State

When in the activated state Java object instances representing the resource adaptor entity may create activities, submit events

and end activities.

• Activated to Deactivating transition: This transition occurs when the

deactivateEntity

method is invoked on the

Resource Management MBean.

C.2.3 Deactivating State

This state is entered from the Activated state. When the resource adaptor entity is in this state it is not able to create new

Activities. Activities that exist in Rhino before the resource adaptor entity transitions to this state may continue to have events

submitted on them, and are able to be ended by the resource adaptor. The resource adaptor will remain in this state until all

Activities created by the resource adaptor entity have ended.

• Deactivating to Inactive transition: This transition occurs when Rhino recognises that all Activity objects submitted by the

resource adaptor entity have ended. The resource adaptor entity will remain in the deactivating state until this condition

occurs.

C.3 Conﬁguration Properties

Each resource adaptor entity may include conﬁguration properties, such as address information of network end points, URLs

to external systems etc. Such conﬁguration properties are passed to the resource adaptor entity via the Resource Management

MBean

createEntity

, and

updateConfigurationProperties

methods.

The conﬁguration properties are a Java language String. This String has a mandatory format of comma delimited pairs of the

form ’property-name=value’.
