Interface ResourceManagementMBean

public interface ResourceManagementMBean

The ResourceManagementMBean interface defines resource adaptor-related management operations.

Using the ResourceManagementMBean a management client may create, remove, activate and deactivate resource adaptor entities, configure resource adaptor properties, and manage resource adaptor entity link names.

The JMX Object Name of a ResourceManagementMBean object is specified by the OBJECT_NAME constant. The Object Name can also be obtained by a management client via the SleeManagementMBean.getResourceManagementMBean() method.

Since:

SLEE 1.1

Properties are specified using a ConfigProperties object. Properties for the resource adaptor that the resource adaptor entity is to be created from can be obtained using the getConfigurationProperties method. The management client must ensure that all properties included in the ConfigProperties object have a non-null value before passing it to this method. The raVerifyConfiguration method is invoked on a resource adaptor object to test validity of the configuration properties for the Resource Adaptor.

Parameters:

id - the identifier of the resource adaptor the resource adaptor entity should be constructed from.

entityName - the name of the resource adaptor entity to create.

properties - the configuration properties for the resource adaptor entity.

Throws:

NullPointerException - if any argument is null.

                                          ManagementException

Reconfigure a resource adaptor entity with new configuration properties. Properties are specified using a ConfigProperties object.

Only properties that need updating need to be included in the ConfigProperties object.

The management client must ensure that all properties included in the ConfigProperties object have a non-null value before passing it to this method.

A Resource Adaptor may elect to support reconfiguration when resource adaptor objects representing its resource adaptor entities are active using the supports-active-reconfiguration attribute of the <resource-adaptor-class> deployment descriptor element. If the value of the supports-active-reconfiguration attribute is False, this method may only be invoked to reconfigure a resource adaptor entity when it is in the Inactive state, or when the SLEE is in the Stopped state. If the value of the supports-active-reconfiguration attribute is True, then a resource adaptor entity may be reconfigured when it, and the SLEE, are in any state, i.e. reconfiguration is possible while the resource adaptor entity is creating activities and firing events in the SLEE.

The raVerifyConfiguration method is invoked on a resource adaptor object to test validity of configuration properties specified as an argument to this method.

Parameters:

entityName - the name of the resource adaptor entity.

properties - the values of configuration properties to be updated for the resource adaptor entity.

Throws:

NullPointerException - if either argument is null.

UnrecognizedResourceAdaptorEntityException - if entityName does not correspond with a resource adaptor entity existing in the SLEE.

InvalidStateException - if the Resource Adaptor's deployment descriptor specified that it did not support active reconfiguration and either the resource adaptor entity is not in the Inactive state or the SLEE is not in the Stopped state.

InvalidConfigurationException - if one or more of the configuration properties has a null value, or if the configuration properties were not valid for the Resource Adaptor as determined by the raVerifyConfiguration method.

ManagementException - if the resource adaptor entity configuration properties could not be updated due to a system-level failure.
