public DiscoveredMachineProvisioningBean()

Method Detail

setAdmin

public void setAdmin(Admin admin)

Description copied from interface: Bean

Set the Admin instance to be used by this Bean.

Specified by:

setAdmin in interface Bean

Parameters:

admin - an Admin instance.

setProperties

public void setProperties(Map<String,String> properties)

Description copied from interface: Bean

The bean properties supplied using a client side bean configuration object, or by plain String key-value pairs.

Specified by:

setProperties in interface Bean

Parameters:

properties - properties to configure this bean.

getProperties

public Map<String,String> getProperties()

Specified by:

getProperties in interface Bean

Returns:

properties used to configure this bean.

afterPropertiesSet

public void afterPropertiesSet()
                        throws Exception

Description copied from interface: Bean

Invoked by a bean factory after it has set all bean properties. This method allows the bean instance to perform non-blocking initialization, which is only possible when all bean properties have been set and to throw an exception in the event of misconfiguration.

Specified by:

afterPropertiesSet in interface Bean

Throws:

Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails.

See Also:

BeanConfigurationException, BeanInitializationException

destroy

public void destroy()
             throws Exception

Description copied from interface: Bean

Invoked by a bean factory on destruction of a singleton.

Specified by:

destroy in interface Bean

Throws:

Exception - in case of shutdown errors. Exceptions will get logged but not re-thrown to allow other beans to release their resources too.

See Also:

BeanConfigException

setProcessingUnit

public void setProcessingUnit(ProcessingUnit pu)

Specified by:

setProcessingUnit in interface ProcessingUnitAware

setProcessingUnitSchema

public void setProcessingUnitSchema(org.openspaces.admin.internal.pu.elastic.ProcessingUnitSchemaConfig schemaConfig)

Specified by:

setProcessingUnitSchema in interface ProcessingUnitAware

getDiscoveredMachinesAsync

public FutureGridServiceAgents getDiscoveredMachinesAsync(long duration,
                                                          TimeUnit unit)

Specified by:

getDiscoveredMachinesAsync in interface NonBlockingElasticMachineProvisioning

Parameters:

duration - - the maximum duration after which a TimeoutException is raised.

unit - - the time unit for the duration

Returns:

a future array of grid service agents that reside in the data center (or cloud region) defined in ElasticMachineProvisioningConfig The caller then filters the result using the criteria defined in ElasticMachineProvisioningConfig.getGridServiceAgentZones() , ElasticMachineProvisioningConfig.isGridServiceAgentZoneMandatory() and ElasticMachineProvisioningConfig.isDedicatedManagementMachines() so it is not mandatory for the implementation to do so.

getConfig

public ElasticMachineProvisioningConfig getConfig()

Specified by:

getConfig in interface NonBlockingElasticMachineProvisioning

Returns:

the configuration used by this object

isStartMachineSupported

public boolean isStartMachineSupported()

Specified by:

isStartMachineSupported in interface NonBlockingElasticMachineProvisioning

Returns:

true if this object supports starting and stopping of machines. False indicates that #startMachinesAsync(CapacityRequirements, long, TimeUnit) and NonBlockingElasticMachineProvisioning.stopMachineAsync(GridServiceAgent, long, TimeUnit) raise UnsupportedOperationException

stopMachineAsync

public FutureStoppedMachine stopMachineAsync(GridServiceAgent agent,
                                             long duration,
                                             TimeUnit unit)

Description copied from interface: NonBlockingElasticMachineProvisioning

Shuts down the grid service agent and the machine. The implementation should be able to close machines that it has not started, but rather an older instance of this object started perhaps with different configuration. This method is non blocking and is idempotent.

Specified by:

stopMachineAsync in interface NonBlockingElasticMachineProvisioning

Returns:

setElasticProcessingUnitMachineIsolation

public void setElasticProcessingUnitMachineIsolation(ElasticProcessingUnitMachineIsolation isolation)

Specified by:

setElasticProcessingUnitMachineIsolation in interface ElasticProcessingUnitMachineIsolationAware

startMachinesAsync

public FutureGridServiceAgent[] startMachinesAsync(CapacityRequirements capacityRequirements,
                                                   ExactZonesConfig zones,
                                                   FailedGridServiceAgent[] failedAgents,
                                                   long duration,
                                                   TimeUnit unit)

Description copied from interface: NonBlockingElasticMachineProvisioning

Starts a new machine with a new grid service agent with the specified grid service agent zones. This method is non blocking and returns a future object with the new grid service agent.

Specified by:

startMachinesAsync in interface NonBlockingElasticMachineProvisioning

Parameters:

capacityRequirements - - total capacity of new machines

zones - - the agent zones.

failedAgents - - list of agents that require recovery

duration - - the maximum duration after which a TimeoutException is raised.

unit - - the time unit for the duration.

Returns:

the grid service agent futures

setElasticMachineProvisioningProgressChangedEventListener

public void setElasticMachineProvisioningProgressChangedEventListener(ElasticMachineProvisioningProgressChangedEventListener machineEventListener)

Specified by:

setElasticMachineProvisioningProgressChangedEventListener in interface ElasticMachineProvisioningProgressChangedEventListenerAware

setElasticGridServiceAgentProvisioningProgressEventListener

public void setElasticGridServiceAgentProvisioningProgressEventListener(ElasticGridServiceAgentProvisioningProgressChangedEventListener agentEventListener)

Specified by:

setElasticGridServiceAgentProvisioningProgressEventListener in interface ElasticGridServiceAgentProvisioningProgressEventListenerAware

cleanupCloudResources

public FutureCleanupCloudResources cleanupCloudResources(long duration,
                                                         TimeUnit unit)

Description copied from interface: NonBlockingElasticMachineProvisioning

Cleanup all cloud resources. This method is called once after the processing unit has undeployed and all machines have been stopped.

Specified by:

cleanupCloudResources in interface NonBlockingElasticMachineProvisioning
