Interface RepositoryManagementMBean

public interface RepositoryManagementMBean

This interface exposes repository management operations and the status of such operations. This interface only provides high level functionality for starting certain management operations and monitoring their outcomes. Parametrisation and configuration of the operations is beyond the scope of this interface and must be achieved by other means. For example through a dedicated MBean of the specific service providing the respective functionality. Furthermore not all operations might be available in all deployments or at all times. However the status should give a clear indication for this case.

The status of an operation is represented by a CompositeData instance consisting at least of the items code, id, and message. Implementations are free to add further items.

The code item is an integer encoding the current status of the respective operation. Valid values and its semantics are:

• 0: Operation not available. For example because the system does not implement the operation or the system is in a state where it does not allow the operation to be carried out (e.g. the operation is already running). The message should give further indication of the exact reason.
• 1: Status not available. Usually because there was no prior attempt to start the operation. The message should give further indication of the exact reason.
• 2: Operation initiated. The message should give further information of when the operation was initiated. This status mean that the operation will be performed some time in the future without impacting overall system behaviour and that no further status updates will be available until this operation is performed next time.
• 3: Operation running.
• 4: Operation succeeded. The message should give further information on how long the operation took to complete.
• 5: Operation failed. The message should give further information on the reason for the failure.

In all cases the message may provide additional information that might be useful in the context of the operation.

The id is an identifier for the invocation of an operation. It is reported as a part of the status for clients to relate the status to invocation. -1 is returned when not available.
