Apache Derby Database Engine and Embedded JDBC Driver 10.17.1.0 · org.apache.derby.mbeans.ManagementMBean

JMX MBean inteface to control visibility of Derby's MBeans. When Derby boots it attempts to register its MBeans. It may fail due to lack of valid permissions. If Derby does not register its MBeans then an application may register the Management implementation of ManagementMBean itself and use it to start Derby's JMX management.

Key properties for registered MBean when registered by Derby:

type=Management
system=runtime system identifier (see overview)

Method Summary

Modifier and Type	Method and Description
public String	Returns: Runtime identifier for the system, null if Derby is not running. getSystemIdentifier() Get the system identifier that this MBean is managing.
public boolean	Returns: true Derby has registered beans, false Derby has not registered any beans. isManagementActive() Is Derby's JMX management active.
public void	startManagement() Inform Derby to start its JMX management by registering MBeans relevant to its current state.
public void	stopManagement() Inform Derby to stop its JMX management by unregistering its MBeans.

Method Detail

getSystemIdentifier	back to summary
public String getSystemIdentifier() Get the system identifier that this MBean is managing. The system identifier is a runtime value to disambiguate multiple Derby systems in the same virtual machine but different class loaders. Returns:String Runtime identifier for the system, null if Derby is not running.
