                            throws NullPointerException,
                                   UnrecognizedResourceAdaptorEntityException,

Activate a resource adaptor entity on all nodes.

The resource adaptor entity must currently have an effective desired state of ResourceAdaptorEntityDesiredState.inactive on at least one live event routing node, as determined by RhinoHousekeepingMBean.getEventRouterNodes(). All per-node desired state for the resource adaptor entity is removed by this method and the default desired state of the resource adaptor entity is set to ResourceAdaptorEntityDesiredState.active (if it is not already). Before this method returns, an attempt is then made to transition the resource adaptor entity to an actual state of ResourceAdaptorEntityActualState.active on all event router nodes where the actual state is currently ResourceAdaptorEntityActualState.inactive. Any node where the resource adaptor entity actual state is ResourceAdaptorEntityActualState.stopping will wait (asynchronously) until the resource adaptor entity reaches the ResourceAdaptorEntityActualState.inactive state and then attempt to transition the resource adaptor entity back to ResourceAdaptorEntityActualState.active.

As a result of this method setting the default desired state to ResourceAdaptorEntityDesiredState.active, any new event router nodes that boot into the cluster will assume an activated state for the resource adaptor entity unless per-node desired state is subsequently created to state otherwise.

Specified by:

activateResourceAdaptorEntity in interface ResourceManagementMBean

Parameters:

entityName - the name of the resource adaptor entity.

Throws:

NullPointerException - if entityName is null.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

InvalidStateException - if the effective desired state of the resource adaptor entity is not ResourceAdaptorEntityDesiredState.inactive on any current event router node.

ManagementException - if the resource adaptor entity could not be activated due to a system-level failure.

Activate a resource adaptor entity on the specified nodes.

The resource adaptor entity must currently have an effective desired state of ResourceAdaptorEntityDesiredState.inactive on all the specified nodes. Per-node desired state for the resource adaptor entity is created for each specified node if it does not already exist and set to ResourceAdaptorEntityDesiredState.active. Before this method returns, an attempt is then made to transition the resource adaptor entity to an actual state of ResourceAdaptorEntityActualState.active on all specified nodes that are current live event router nodes where the actual state is ResourceAdaptorEntityActualState.inactive. Any node where the resource adaptor entity actual state is ResourceAdaptorEntityActualState.stopping will wait (asynchronously) until the resource adaptor entity reaches the ResourceAdaptorEntityActualState.inactive state and then attempt to transition the resource adaptor entity back to ResourceAdaptorEntityActualState.active.

The specified nodes do not have to be current cluster members. For example, this method can be used to set the resource adaptor entity desired state on nodes yet to be started.

This method does not affect the default desired state of the resource adaptor entity.

Parameters:

entityName - the name of the resource adaptor entity.

nodeIDs - the node IDs of the nodes to activate the resource adaptor entity on.

Throws:

NullPointerException - if either argument is null.

InvalidArgumentException - if nodeIDs is zero-length or contains invalid node IDs.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

InvalidStateException - if the effective desired state of the resource adaptor entity is not ResourceAdaptorEntityDesiredState.inactive on all specified nodes.

ManagementException - if the resource adaptor entity could not be activated due to a system-level failure.

                                     ManagementException

Deactivate a resource adaptor entity on all nodes.

The resource adaptor entity must currently have an effective desired state of ResourceAdaptorEntityDesiredState.active on at least one live event routing node, as determined by RhinoHousekeepingMBean.getEventRouterNodes(). All per-node desired state for the resource adaptor entity is removed by this method and the default desired state of the resource adaptor entity is set to ResourceAdaptorEntityDesiredState.inactive (if it is not already). The resource adaptor entity then transitions to an actual state of ResourceAdaptorEntityActualState.stopping on all event router nodes where the actual state is currently ResourceAdaptorEntityActualState.active before this method returns.

As a result of this method setting the default desired state to ResourceAdaptorEntityDesiredState.inactive, any new event router nodes that boot into the cluster will assume an inactive state for the resource adaptor entity unless per-node desired state is subsequently created to state otherwise.

Specified by:

deactivateResourceAdaptorEntity in interface ResourceManagementMBean

Parameters:

entityName - the name of the resource adaptor entity.

Throws:

NullPointerException - if entityName is null.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

InvalidStateException - if the effective desired state of the resource adaptor entity is not ResourceAdaptorEntityDesiredState.active on any current event router node.

ManagementException - if the resource adaptor entity could not be deactivated due to a system-level failure.

deactivateResourceAdaptorEntity

void deactivateResourceAdaptorEntity(String entityName,
                                     int[] nodeIDs)
                              throws NullPointerException,
                                     InvalidArgumentException,
                                     UnrecognizedResourceAdaptorEntityException,

                                     ManagementException

Deactivate a resource adaptor entity on the specified nodes.

The resource adaptor entity must currently have an effective desired state of ResourceAdaptorEntityDesiredState.active on all the specified nodes. Per-node desired state for the resource adaptor entity is created for each specified node if it does not already exist and set to ResourceAdaptorEntityDesiredState.inactive. The resource adaptor entity then transitions to an actual state of ResourceAdaptorEntityActualState.stopping on all specified nodes that are current live event router nodes where the actual state is ResourceAdaptorEntityActualState.active before this method returns.

The specified nodes do not have to be current cluster members. For example, this method can be used to set the resource adaptor entity desired state on nodes yet to be started.

This method does not affect the default desired state of the resource adaptor entity.

If the resource adaptor entity owns replicated activities on nodes that transition to ResourceAdaptorEntityActualState.stopping then those activities are left to drain normally by this method. If ownership of these activities should be reassigned to allow the resource adaptor entity to return to the ResourceAdaptorEntityActualState.inactive state quicker then deactivateResourceAdaptorEntity(String, int[], int[]) should be used instead. Alternatively reassignActivities(String, int[], int[]) may be used after deactivation to perform this reassignment.

Parameters:

entityName - the name of the resource adaptor entity.

nodeIDs - the node IDs of the nodes to deactivate the resource adaptor entity on.

Throws:

NullPointerException - if either argument is null.

InvalidArgumentException - if nodeIDs is zero-length or contains invalid node IDs.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

InvalidStateException - if the effective desired state of the resource adaptor entity is not ResourceAdaptorEntityDesiredState.active on all specified nodes.

ManagementException - if the resource adaptor entity could not be deactivated due to a system-level failure.

deactivateResourceAdaptorEntity

void deactivateResourceAdaptorEntity(String entityName,
                                     int[] nodeIDs,
                                     int[] reassignActivitiesToNodeIDs)
                              throws NullPointerException,
                                     InvalidArgumentException,

Deactivate a resource adaptor entity on the specified nodes and reassign replicated activities owned by the resource adaptor entity on the deactivating nodes to other cluster nodes.

The resource adaptor entity must currently have an effective desired state of ResourceAdaptorEntityDesiredState.active on all the specified nodes. Per-node desired state for the resource adaptor entity is created for each specified node if it does not already exist and set to ResourceAdaptorEntityDesiredState.inactive. The resource adaptor entity then transitions to an actual state of ResourceAdaptorEntityActualState.stopping on all specified nodes that are current live event router nodes where the actual state is ResourceAdaptorEntityActualState.active before this method returns.

The specified nodes do not have to be current cluster members. For example, this method can be used to set the resource adaptor entity desired state on nodes yet to be started.

This method does not affect the default desired state of the resource adaptor entity.

This method has several modes of operation, depending on the value of the reassignActivitiesToNodeIDs parameter:

• if reassignActivitiesToNodeIDs is null, this method behaves in the same way as the deactivateResourceAdaptorEntity(String, int[]) method, ie. no replicated activity reassignment takes place

• if reassignActivitiesToNodeIDs is a zero-length array, replicated activities will be reassigned to any other cluster nodes that are capable of taking ownership of the activities; if no nodes satisfy this criteria no activity reassignment takes place

• if reassignActivitiesToNodeIDs is an array with at least one element, replicated activities will be reassigned to the specified node(s).

Replicated activities for a resource adaptor entity will only be reassigned from a node if the node meets the following conditions:

• the node is a live cluster member providing event routing functions, ie. not a quorum node

• the resource adaptor entity has an actual state of ResourceAdaptorEntityActualState.active on the node prior to this method being invoked

• the SLEE has an actual state of SleeActualState.running or SleeActualState.stopping on the node.

Replicated activities for a resource adaptor entity may only be reassigned to a node if the node meets the following conditions:

• the node is a live cluster member providing event routing functions, ie. not a quorum node

• the resource adaptor entity has both a desired state of ResourceAdaptorEntityDesiredState.active and an actual state of ResourceAdaptorEntityActualState.active on the node

• the SLEE has an actual state of SleeActualState.running state on the node.

Parameters:

entityName - the name of the resource adaptor entity.

nodeIDs - the node IDs of the nodes to deactivate the resource adaptor entity on.

reassignActivitiesToNodeIDs - the set of nodes to reassign replicated activities to.

Throws:

NullPointerException - if entityName or nodeIDs is null.

InvalidArgumentException - if nodeIDs is zero-length or contains invalid node IDs, or if reassignActivitiesToNodeIDs is non-null but the resource adaptor entity is not replicating or if the target nodes are invalid.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

InvalidStateException - if the effective desired state of the resource adaptor entity is not ResourceAdaptorEntityDesiredState.active on all specified nodes.

ManagementException - if the resource adaptor entity could not be deactivated due to a system-level failure.

reassignActivities

void reassignActivities(String entityName,
                        int[] fromNodeIDs,

                 throws NullPointerException,
                        InvalidArgumentException,
                        UnrecognizedResourceAdaptorEntityException,
                        InvalidStateException,
                        ManagementException

Reassign replicated activities owned by a resource adaptor entity on the specified nodes to other cluster nodes. The resource adaptor entity must be a replicating resource adaptor entity.

This method has two modes of operation, depending on the value of the toNodeIDs parameter:

• if toNodeIDs is a zero-length array, replicated activities will be reassigned to any other cluster nodes that are capable of taking ownership of the activities

• if toNodeIDs is an array with at least one element, replicated activities will be reassigned to the specified node(s).

Replicated activities for a resource adaptor entity may only be reassigned from a node if the node meets the following conditions:

• the node is a live cluster member providing event routing functions, ie. not a quorum node

• the resource adaptor entity has an actual state of ResourceAdaptorEntityActualState.active or ResourceAdaptorEntityActualState.stopping state on the node

• the SLEE has an actual state of SleeActualState.running or SleeActualState.stopping state on the node.

Replicated activities for a resource adaptor entity may only be reassigned to a node if the node meets the following conditions:

• the node is a live cluster member providing event routing functions, ie. not a quorum node

• the resource adaptor entity has both a desired state of ResourceAdaptorEntityDesiredState.active and an actual state of ResourceAdaptorEntityActualState.active on the node

• the SLEE has an actual state of SleeActualState.running state on the node.

Parameters:

entityName - the name of the resource adaptor entity.

fromNodeIDs - the node IDs of the nodes to reassign activities from.

toNodeIDs - the node IDs of the nodes to reassign the activities to.

Throws:

NullPointerException - if any argument is null.

InvalidArgumentException - if entityName does not correspond with a replicating resource adaptor, or if fromNodeIDs is zero-length or contains invalid node IDs, or if toNodeIDs is contains invalid node IDs.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

InvalidStateException - if the resource adaptor entity or SLEE is not in the appropriate state on any relevant node as required above, or if toNodeIDs is zero-length and there are no remaining nodes that the activities may be reassigned to.

ManagementException - if the activities could not be reassigned due to a system-level failure.

                                      ManagementException

Get the current state of a resource adaptor entity on each of the specified nodes.

This method translates the desired or actual state of the resource adaptor entity on each specified node to an equivalent JAIN SLEE-defined state depending on the presence of the node. For nodes that are current live event router nodes, actual state is used. For nodes that are not cluster members or are not event router nodes, desired state is used.

Parameters:

entityName - the name of the resource adaptor entity.

nodeIDs - the node IDs of the nodes to return the resource adaptor entity’s state for.

Returns:

an array of resource adaptor entity state objects. This array will be the same length as the supplied nodeIDs array, and if states = getState(entityName, nodeIDs) then states[i] equals the state of the resource adaptor entity on node nodeIDs[i]. If there is no state information for the resource adaptor entity on a particular node, ResourceAdaptorEntityState.INACTIVE is returned as the resulting state for the resource adaptor entity on that node.

Throws:

NullPointerException - if either argument is null.

Set the stopping priority for a resource adaptor entity. The stopping priority determines the order in which services and resource adaptor entities together are stopped when the SLEE transitions from the RUNNING state to the STOPPING state.

Priorities are values between -128 and 127. If a component (service or resource adaptor entity), X, has a numerically higher priority value than another component, Y, then X will be stopped before Y. Components with the same priority may be stopped in an arbitrary order, or may be stopped concurrently.

Parameters:

entityName - the name of the resource adaptor entity.

priority - the stopping priority for the resource adaptor entity.

Throws:

NullPointerException - if entityName is null.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

ManagementException - if the stopping priority of the resource adaptor entity could not be updated due to a system-level failure.
