Method Detail

setPollingIntervalSeconds

void setPollingIntervalSeconds(int seconds)

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

Parameters:

seconds - - the polling interval in seconds

getPollingIntervalSeconds

int getPollingIntervalSeconds()

getMaxConcurrentRelocationsPerMachine

int getMaxConcurrentRelocationsPerMachine()

setMaxConcurrentRelocationsPerMachine

void setMaxConcurrentRelocationsPerMachine(int maxNumberOfConcurrentRelocationsPerMachine)

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.

Parameters:

maxNumberOfConcurrentRelocationsPerMachine -

setAtMostOneContainerPerMachine

void setAtMostOneContainerPerMachine(boolean atMostOneContainerPerMachine)

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

Since:

8.0.3

setAllowAboveAverageMemoryPerMachine

void setAllowAboveAverageMemoryPerMachine(boolean allowAboveAverageMemoryPerMachine)

Allows a single machine to accommodate for more than the average maximum memory allocation of a Processing Unit. The average is calculated like so : (memoryCapacityPerContainer * totalNumberOfProcessingUnitInstances) / minimumNumberOfMachines

Since:

9.7.0

isAllowAboveAverageMemoryPerMachine

boolean isAllowAboveAverageMemoryPerMachine()

setAtMostOneConcurrentRelocation

void setAtMostOneConcurrentRelocation(boolean atMostOneConcurrentRelocation)

Limits the number of concurrent relocations for the entire cluster to 1. Notice this is an aggregated property across all machines.

Since:

9.7.0
