Method Detail

getBeanClassName

public String getBeanClassName()

Description copied from interface: BeanConfig

The Bean implementation class name corresponding to this BeanConfig.

Specified by:

getBeanClassName in interface BeanConfig

Returns:

the name of the admin Bean implementation class.

setProperties

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

Description copied from interface: BeanConfig

Set with String key-value pairs to configure properties belonging to this bean. Overrides all previously set properties.

Specified by:

setProperties in interface BeanConfig

Parameters:

properties - the properties to configure this bean object.

getProperties

public Map<String,String> getProperties()

Description copied from interface: BeanConfig

Get the String key-value pairs properties used to configure this bean.

Specified by:

getProperties in interface BeanConfig

Returns:

the properties used to configure this bean object.

getMinimumNumberOfCpuCoresPerMachine

public double getMinimumNumberOfCpuCoresPerMachine()

Description copied from interface: ElasticMachineProvisioningConfig

Gets the minimum number of CPU cores per machine. This value is used during deployment to calculate number of partitions (partitions = maxNumberOfCpuCores/minNumberOfCpuCoresPerMachine)

Specified by:

getMinimumNumberOfCpuCoresPerMachine in interface ElasticMachineProvisioningConfig

setMinimumNumberOfCpuCoresPerMachine

public void setMinimumNumberOfCpuCoresPerMachine(double minimumNumberOfCpuCoresPerMachine)

Sets an assessment for the minimum number of CPU cores per machine. If not specified Processing Unit deployment calls detectMinimumNumberOfCpuCoresPerMachine(org.openspaces.admin.Admin) to get an assessment of minimum number of CPU cores per machine.

Since:

8.0.0

getGridServiceAgentZones

public String[] getGridServiceAgentZones()

Description copied from interface: ElasticMachineProvisioningConfig

Gets the list of zones that can be discovered and started by this machine provisioning. By default returns an empty array. For example: String[] {} - Grid Service Agents are started without -Dcom.gs.zones (requires that ElasticMachineProvisioningConfig.isGridServiceAgentZoneMandatory() is false) String[] {"zoneA"} - Grid Service Agents are started with -Dcom.gs.zones=zoneA (or without -Dcom.gs.zones if ElasticMachineProvisioningConfig.isGridServiceAgentZoneMandatory() is false) String[] {"zoneA","zoneB"} - Grid Service Agents are started with -Dcom.gs.zones=zoneA or -Dcom.gs.zones=zoneB or -Dcom.gs.zones=zoneA,zoneB (or without -Dcom.gs.zones if ElasticMachineProvisioningConfig.isGridServiceAgentZoneMandatory() is false)

Specified by:

getGridServiceAgentZones in interface ElasticMachineProvisioningConfig

setGridServiceAgentZones

public void setGridServiceAgentZones(String[] zones)

Sets the list of zones that can be discovered and started by this machine provisioning. For example: String[] {} - Grid Service Agents are started without -Dcom.gs.zones (requires that isGridServiceAgentZoneMandatory() is false) String[] {"zoneA"} - Grid Service Agents are started with -Dcom.gs.zones=zoneA (or without -Dcom.gs.zones if isGridServiceAgentZoneMandatory() is false) String[] {"zoneA","zoneB"} - Grid Service Agents are started with -Dcom.gs.zones=zoneA or -Dcom.gs.zones=zoneB or -Dcom.gs.zones=zoneA,zoneB (or without -Dcom.gs.zones if isGridServiceAgentZoneMandatory() is false)

Since:

8.0.1

setReservedMemoryCapacityPerMachineInMB

public void setReservedMemoryCapacityPerMachineInMB(long reservedInMB)

Sets the expected amount of memory per machine that is reserved for processes other than grid containers. These include Grid Service Manager, Lookup Service or any other daemon running on the system. Default value is 1024 MB. For example, by default, a 16GB server can run 3 containers 5GB each, since it approximately leaves 1024MB memory free.

Parameters:

reservedInMB - - amount of reserved memory in MB

Since:

8.0.1

setReservedDriveCapacityPerMachineInMB

public void setReservedDriveCapacityPerMachineInMB(Map<String,Long> reservedInMB)

Sets the expected amount of disk drive size per machine that is reserved for processes other than grid containers. These include Grid Service Manager, Lookup Service or any other daemon running on the system. Default value is 0 MB.

Parameters:

reservedInMB - - amount of reserved disk drive in MB

Since:

setReservedCpuCapacityPerMachineInMB

public void setReservedCpuCapacityPerMachineInMB(double reservedCpu)

Sets the expected CPU cores per machine that is reserved for processes other than grid containers. These include Grid Service Manager, Lookup Service or any other daemon running on the system. Default value is 0 cpu cores.

Parameters:

reservedCpu - - number of reserved CPU cores

Since:

setReservedCapacityPerMachine(CapacityRequirements)

getReservedCapacityPerMachine

public CapacityRequirements getReservedCapacityPerMachine()

Description copied from interface: ElasticMachineProvisioningConfig

Gets the expected amount of memory,cpu,disk,etc... per machine that is reserved for processes other than grid containers. These include Grid Service Manager, Lookup Service or any other daemon running on the system. For example, a machine with a 16GB server and 1GB reserved can run 3 containers 5GB each.

Specified by:

getReservedCapacityPerMachine in interface ElasticMachineProvisioningConfig

setReservedCapacityPerMachine

public void setReservedCapacityPerMachine(CapacityRequirements capacityRequirements)

Sets the expected amount of memory, cpu, drive space (per machine) that is reserved for processes other than processing units. These include Grid Service Manager, Lookup Service or any other daemon running on the system. Default value is 1024 MB RAM. For example, by default, a 16GB server can run 3 containers 5GB each, since it approximately leaves 1024MB memory free.

Parameters:

capacityRequirements - - specifies the reserved memory/cpu/disk space

isDedicatedManagementMachines

public boolean isDedicatedManagementMachines()

Description copied from interface: ElasticMachineProvisioningConfig

By default is false, which means that a Grid Service Agents may run a management process. If true, it means that agents started and discovered by this machine provisioning cannot run a GridServiceManager nor LookupService nor ElasticServiceManager Usually setting this value to true means that #getReservedCapacityPerMachineInMB() memory can be decreased, since no memory needs to be reserved for management processes.

Specified by:

isDedicatedManagementMachines in interface ElasticMachineProvisioningConfig

setDedicatedManagementMachines

public void setDedicatedManagementMachines(boolean isDedicatedManagementMachines)

A false value indicates that Grid Service Agents may run a management process. True indicates that agents started and discovered by this machine provisioning cannot run a GridServiceManager nor LookupService nor ElasticServiceManager Usually setting this value to true means that setReservedMemoryCapacityPerMachineInMB(long) can be decreased, since no memory needs to be reserved for management processes.

Since:

8.0.1

isGridServiceAgentZoneMandatory

public boolean isGridServiceAgentZoneMandatory()

Description copied from interface: ElasticMachineProvisioningConfig

By default is false, which means that Grid Service Agents without a zone can be started and discovered by this machine provisioning. When true, each started or discovered agent much have one or more of the zones described in ElasticMachineProvisioningConfig.getGridServiceAgentZones()

Specified by:

isGridServiceAgentZoneMandatory in interface ElasticMachineProvisioningConfig

setGridServiceAgentZoneMandatory

public void setGridServiceAgentZoneMandatory(boolean zoneMandatory)

A false value indicates that Grid Service Agents without a zone can be started and discovered by this machine provisioning. True indicates that each started or discovered agent much have one or more of the zones described in setGridServiceAgentZones(String[])
