Class ManualCapacityScaleConfig

java.lang.Object
  org.openspaces.admin.pu.elastic.config.ManualCapacityScaleConfig

All Implemented Interfaces:

Externalizable, Serializable, BeanConfig, ScaleStrategyAgentZonesAwareConfig, ScaleStrategyCapacityRequirementConfig, ScaleStrategyConfig

public class ManualCapacityScaleConfig
extends Object
implements ScaleStrategyConfig, ScaleStrategyCapacityRequirementConfig, ScaleStrategyAgentZonesAwareConfig, Externalizable

Defines a manual scaling strategy that consumes the specified memory capacity. When enabled the processing unit scales out whenever the specified memory capacity deviates from the actual memory capacity. When a backup partition is enabled (which usually is the case), the specified memory capacity is the total memory occupied by the primary partition instances and the backup partition instances.

ManualCapacityScaleConfig

public ManualCapacityScaleConfig()

Default constructor

ManualCapacityScaleConfig

public ManualCapacityScaleConfig(Map<String,String> properties)

Method Detail

setMemoryCapacityInMB

public void setMemoryCapacityInMB(long memory)

Description copied from interface: ScaleStrategyCapacityRequirementConfig

Specifies the total memory capacity.

Specified by:

setMemoryCapacityInMB in interface ScaleStrategyCapacityRequirementConfig

getMemoryCapacityInMB

public long getMemoryCapacityInMB()
                           throws NumberFormatException

Specified by:

getMemoryCapacityInMB in interface ScaleStrategyCapacityRequirementConfig

Throws:

NumberFormatException

setNumberOfCpuCores

public void setNumberOfCpuCores(double cpuCores)

Description copied from interface: ScaleStrategyCapacityRequirementConfig

Specifies the total CPU cores.

Specified by:

setNumberOfCpuCores in interface ScaleStrategyCapacityRequirementConfig

getNumberOfCpuCores

public double getNumberOfCpuCores()

Specified by:

getNumberOfCpuCores in interface ScaleStrategyCapacityRequirementConfig

setPollingIntervalSeconds

public void setPollingIntervalSeconds(int seconds)

Description copied from interface: ScaleStrategyConfig

Sets the polling interval in which the scale strategy SLA is monitored and enforced.

Specified by:

setPollingIntervalSeconds in interface ScaleStrategyConfig

Parameters:

seconds - - the polling interval in seconds

getPollingIntervalSeconds

public int getPollingIntervalSeconds()

Specified by:

getPollingIntervalSeconds in interface ScaleStrategyConfig

getMaxConcurrentRelocationsPerMachine

public int getMaxConcurrentRelocationsPerMachine()

Specified by:

getMaxConcurrentRelocationsPerMachine in interface ScaleStrategyConfig

setMaxConcurrentRelocationsPerMachine

public void setMaxConcurrentRelocationsPerMachine(int maxNumberOfConcurrentRelocationsPerMachine)

Description copied from interface: ScaleStrategyConfig

Specifies the number of processing unit instance relocations each machine can handle concurrently. Relocation requires network and CPU resources, and too many concurrent relocations per machine may degrade its performance temporarily. The data recovery running as part of the relocation uses by default 4 threads. So the total number of threads is 4 multiplied by the specified value. By setting this value higher than 1, processing unit rebalancing completes faster, by using more machine cpu and network resources. Default value is 1. This is an advanced property setting.

Specified by:

setMaxConcurrentRelocationsPerMachine in interface ScaleStrategyConfig

isAtMostOneContainersPerMachine

@Deprecated
public boolean isAtMostOneContainersPerMachine()

Deprecated.

isAtMostOneContainerPerMachine

public boolean isAtMostOneContainerPerMachine()

Specified by:

When set to true, at most one Grid Service Container for this Processing Unit is started per machine.

Specified by:

setAtMostOneContainerPerMachine in interface ScaleStrategyConfig
