public interface ResourceManagerMBean
extends ConfigurationMBean

A ResourceManagerMBean represents a resource consumption management policy. A policy controls and governs the use of shared resources in a Server runtime, by a Partition that the policy is attached to. A resource manager holds information on constraints and recourse actions for different resources in a Server instance.

A system administrator defines a resource manager and configures child MBeans that represent particular combinations of shares and usage limits of various resources in the Server runtime.

The system administrator may then assign the resource manager to one or more Partitions to ensure fair allocation of shared resources to collocated Domain Partitions, and to ensure that one Partition doesn't exhaust shared resources (potentially affecting other collocated Partitions).

The set of resources on which resource management policies can be assigned to, and the child MBeans through which they can be configured are:

1. File Open: FileOpenMBean
2. Heap Retained: HeapRetainedMBean
3. CPU Utilization: CpuUtilizationMBean

Method Detail

getFileOpen

FileOpenMBean getFileOpen()

Gets the "File Open" policy for this resource manager.

Returns:

The "File Open" policy for this resource manager

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

createFileOpen

FileOpenMBean createFileOpen(java.lang.String name)

This is the factory method for creating "File Open" policy for this resource manager. The new FileOpenMBean which is created will have this resource manager as its parent and must be destroyed with the destroyFileOpen(FileOpenMBean) method. The "File open" policy governs the number of open files. This includes files that have been opened through java.io ( FileInputStream, FileOutputStream, RandomAccessFile etc) and java.nio (NIO file channels) APIs.

Parameters:

name - the name of the Policy to be created

Returns:

A FileOpenMBean that represents the "File Open" policy for this resource manager.

destroyFileOpen

void destroyFileOpen(FileOpenMBean fileOpenMBean)

Destroys and removes a "File Open" policy corresponding to the {code fileOpenMBean} parameter, which is a child of this resource manager.

Parameters:

fileOpenMBean - The FileOpenMBean to be removed from the resource manager.

getHeapRetained

HeapRetainedMBean getHeapRetained()

Gets the "Heap Retained" policy for this resource manager.

Returns:

The "Heap Retained" policy for this resource manager

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

createHeapRetained

HeapRetainedMBean createHeapRetained(java.lang.String name)

This is the factory method for creating "Heap Retained" policy for this resource manager. The new HeapRetainedMBean which is created will have this resource manager as its parent and must be destroyed with the destroyHeapRetained(HeapRetainedMBean) method. The "Heap Retained" policy tracks the amount of Heap memory retained(in use) by the Partition.

Parameters:

name - the name of the Policy to be created

Returns:

A HeapRetainedMBean that represents the "Heap Retained" policy for this resource manager.

destroyHeapRetained

void destroyHeapRetained(HeapRetainedMBean heapRetainedMBean)

Destroys and removes a "Heap Retained" policy corresponding to the {code heapRetainedMBean} parameter, which is a child of this resource manager.

Parameters:

heapRetainedMBean - The HeapRetainedMBean to be removed from the resource manager.

getCpuUtilization

CpuUtilizationMBean getCpuUtilization()

Gets the "CPU Utilization" policy for this resource manager.

Returns:

The "CPU Utilization" policy for this resource manager

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.

createCpuUtilization

CpuUtilizationMBean createCpuUtilization(java.lang.String name)

This is the factory method for creating "CPU Utilization" policy for this resource manager. The new CpuUtilizationMBean which is created will have this resource manager as its parent and must be destroyed with the destroyCpuUtilization(CpuUtilizationMBean) method. The "CPU Utilization" resource type tracks the percentage of CPU time utilized by a Domain Partition with respect to the available CPU time to the Server runtime.

Parameters:

name - the name of the Policy to be created

Returns:

A CpuUtilizationMBean that represents the "CPU Utilization" policy for this resource manager.

destroyCpuUtilization

void destroyCpuUtilization(CpuUtilizationMBean cpuUtilizationMBean)

Destroys and removes a "CPU Utilization" policy corresponding to the {code cpuUtilizationMBean} parameter, which is a child of this resource manager.

Parameters:

cpuUtilizationMBean - The CpuUtilizationMBean to be removed from the resource manager.

getRestartLoopProtection

RestartLoopProtectionMBean getRestartLoopProtection()

Gets the "Restart Loop Protection" for this resource manager.

Returns:

The "Restart Loop Protection" for this resource manager

Changes to this property are dynamic and thus take effect immediately without restarting the server or partition.
