public interface ProcessingUnitInstance
extends GridComponent, Iterable<ServiceDetails>, StatisticsMonitor

A processing unit instance is an actual running instance of a processing unit. For example, when deploying a processing unit with 4 instance, there will be eventually 4 instances of the processing unit.

Method Detail

getProcessingUnitInstanceName

String getProcessingUnitInstanceName()

Get this processing unit instance String representation.
If this processing unit instance represents a Space instance, this method will return a similar result to SpaceInstance.getSpaceInstanceName(), but with the processing unit name as the Space name. Otherwise, it will return: {Processing unit name} [instance id] - the name of this processing unit (see getName()) and the instance id (see getInstanceId()); for example, MyPU [3]

Returns:

this processing unit instance String representation.

Since:

8.0.5

destroy

void destroy()

Destroy the instance. If breaches the SLA, will instantiate the instance again.

decrement

void decrement()

Decrements the instance (and destroying it in the process). Will not attempt to create it again.

See Also:

ProcessingUnit.canDecrementInstance()

relocate

void relocate(GridServiceContainer gridServiceContainerToRelocateTo)

Relocates the instance to the provided GridServiceContainer.

Note, the current processing instance is unusable once this call has been made. If the relocated processing unit instance is needed, or waiting for the relocation is required, use relocateAndWait(org.openspaces.admin.gsc.GridServiceContainer) or relocateAndWait(org.openspaces.admin.gsc.GridServiceContainer, long, java.util.concurrent.TimeUnit).

relocateAndWait

ProcessingUnitInstance relocateAndWait(GridServiceContainer gridServiceContainerToRelocateTo)

Relocates the instance to the provided GridServiceContainer. The relocated instance will be returned waiting for it indefinitely.

relocateAndWait

ProcessingUnitInstance relocateAndWait(GridServiceContainer gridServiceContainerToRelocateTo,
                                       long timeout,
                                       TimeUnit timeUnit)

Relocates the instance to the provided GridServiceContainer. The relocated instance will be returned waiting for it for the provided timeout.

relocate

void relocate()

Relocates the instance to any suitable GridServiceContainer.

Note, the current processing instance is unusable once this call has been made. If the relocated processing unit instance is needed, or waiting for the relocation is required, use relocateAndWait() or relocateAndWait(long, java.util.concurrent.TimeUnit) .

relocateAndWait

ProcessingUnitInstance relocateAndWait()

Relocates the any suitable GridServiceContainer. The relocated instance will be returned waiting for it indefinitely.

relocateAndWait

ProcessingUnitInstance relocateAndWait(long timeout,
                                       TimeUnit timeUnit)

Relocates the any suitable GridServiceContainer. The relocated instance will be returned waiting for it for the provided timeout.

restart

void restart()

Restarts the processing unit instance. Note, if this instance is running an embedded space instance, and the space instance is primary and there is a backup around as well, this method is handy to "turn" the backup to primary.

Note, the current processing unit instance is unusable once this call has been made. If the restarted processing unit instance is needed, or waiting for the restart is required, use restartAndWait() or restartAndWait(long, java.util.concurrent.TimeUnit).

restartAndWait

ProcessingUnitInstance restartAndWait()

Restarts the processing unit instance and waits indefinitely for the restarted processing unit instance returning it.

See Also:

restart()

restartAndWait

ProcessingUnitInstance restartAndWait(long timeout,
                                      TimeUnit timeUnit)

Restarts the processing unit instance and waits for the restarted processing unit instance returning it for the provided timeout.
