On the Configuration tab, you can edit fields. On the Runtime tab, you can look at read-only information. The Runtime tab is available only when the server is running.

 

Configuration tab

Name

Specifies a logical name for the server. Server names must be unique within a node. However, for multiple nodes within a cluster, you may have different servers with the same server name as long as the server and node pair are unique. For example, a server named server1 in a node named node1 in the same cluster with a server named server1 in a node named node2 is allowed. Configuring two servers named server1 in the same node is not allowed. WebSphere uses the server name for administrative actions, such as referencing the server in scripting. For WebSphere Application Server for z/OS, this property is sometimes called the long name.

Data type	String
Default	server1

Application Class loader Policy

Specifies whether to use a single class loader to load all applications or to use a different class loader for each application.

The options are SINGLE and MULTIPLE. The default is to use a separate class loader for each application (MULTIPLE).

Data type	String
Default	MULTIPLE

Application Classloading Mode

Specifies whether the class loader should search in the parent class loader or in the application class loader first to load a class. The standard for Developer Kit class loaders and WebSphere class loaders is PARENT_FIRST. By specifying PARENT_LAST, your application can override classes contained in the parent class loader, but this action can potentially result in ClassCastException or LinkageErrors if you have mixed use of overridden classes and non-overridden classes.

The options are PARENT_FIRST and PARENT_LAST. The default is to search in the parent class loader before searching in the application class loader to load a class.

Data type	String
Default	PARENT_FIRST
