that remain unchanged from WebSphere Application Server V5:
- Distributed name space: For additional scalability, the name space for a cell is distributed among the various servers. The deployment manager, node agent, and application server processes all host a name server. The default initial context for a server is its server root. System artifacts, such as EJB homes and resources, are bound to the server root of the server with which they are associated.
- Transient and persistent partitions: The name space is partitioned into transient areas and persistent areas. Server roots are transient. System-bound artifacts such as EJB homes and resources are bound under server roots. There is a cell persistent root, which can be used for cell-scoped persistent bindings, and a node persistent root, which can be used to bind objects with a node scope.
- Federated name space structure: A name space is a collection of all names bound to a particular name server. A name space can contain naming context bindings to contexts located in other servers. If this is the case, the name space is said to be a federated name space, because it is a collection of name spaces from multiple servers. The name spaces link together to cooperatively form a single logical name
The name space for the WebSphere Application Server V6 cell is federated among the deployment manager, node agents, and application servers of the cell. Every server process hosts a name server. All name servers provide the same logical view of the cell name space, with the various server roots and persistent partitions of the name space being interconnected by means of the single logical name space.
- Configured bindings: Administrators can configure bindings into the name space. A configured binding is different from a programmatic binding in that the system creates the binding every time a server is started, even if the target context is in a transient partition.
- Support for CORBA Interoperable Naming Service (INS) object URLs WebSphere Application Server contains support for CORBA object URLs (corbaloc and corbaname) as JNDI provider URLs and lookup names
