MBeanHome
interface.)Provides methods for retrieving information about the Java Virtual Machine (JVM) within with the current server instance is running. You cannot change the JVM's operating parameters while the JVM is active. Instead, use the startup options that are described in the JVM's documentation.
These methods can be used for any type of JVM that WebLogic Server supports.
This is a type-safe interface for a
WebLogic Server MBean, which you can import into your client
classes and access through
weblogic.management.MBeanHome
. As of 9.0, the
MBeanHome
interface and all type-safe interfaces for
WebLogic Server MBeans are deprecated. Instead, client classes that
interact with WebLogic Server MBeans should use standard JMX design
patterns in which clients use the
javax.management.MBeanServerConnection
interface to
discover MBeans, attributes, and attribute types at runtime. For
more information, see "Developing Manageable Applications with JMX"
on http://www.oracle.com/technology/documentation/index.html.
