WAS scripting commands use the underlying JMX classes...

• ObjectName
• Attribute
• AttributeList

The ObjectName class identifies running objects and consists of the following elements...

• The domain name WebSphere.

• Several key properties...

  type	Type of object that is accessible through the MBean, for example, ApplicationServer, and EJBContainer.
  name	Display name of the particular object, for example, MyServer.
  node	Name of the node on which the object runs.
  process	Name of the server process in which the object runs.
  mbeanIdentifier	Correlates the MBean instance with corresponding configuration data.

When ObjectName classes are represented by strings, they have the following pattern:

[domainName]:property=value[,property=value]*

For example, you can specify...

WebSphere:name="My Server",type=ApplicationServer,node=n1,*

...to specify an appserver named My Server on node n1.

The asterisk (*) is a wildcard character, used so that you do not have to specify the entire set of key properties.

The AdminControl commands that take strings as parameters expect strings that look like this example when specifying running objects (MBeans). You can obtain the object name for a running object with the getObjectName command.

Attributes of these objects consist of a name and a value. You can extract the name and value with the getName and the getValue methods that are available in the javax.management.Attribute class. You can also extract a list of attributes.
