The CORBA Name Service is a layered product. The CORBA Name Service is installed as part of the Oracle Tuxedo product. For a complete description of the supported platforms and the installation procedure, see Installing the Oracle Tuxedo System.Figure 1‑1 presents an overview of the CORBA Name Service.Figure 1‑1 CORBA Name ServiceFigure 1‑2 shows how a namespace might be used to store objects that make up an order entry application.Figure 1‑2 An Oracle Tuxedo NamespaceThe illustrated application organizes its namespace by geographic region, then by department. To implement the namespace using the objects in the CORBA Name Service, each shadowed box would be implemented by a NamingContext object. A NamingContext object contains a list of CosNaming::Name data structures that have been bound to application objects or to other NamingContext objects. NamingContext objects are traversed to locate a particular name. For example, the logical name California.Manufacturing.Order can be used to locate the Order object.A CosNaming::Name data structure is not simply a string of alphanumeric characters; it is a sequence of one or more CosNaming::NameComponent data structures. Each CosNaming::NameComponent data structure contains two strings, id and kind. The CORBA Name Service does not interpret or manage these strings, except to ensure that each ID is unique within a given NamingContext object.Oracle Tuxedo CORBA server applications use the bind() method of the NamingContext object to bind a name to an application object contained in the server application. Oracle Tuxedo CORBA client applications use the resolve method of a NamingContext object to locate an object using a binding.The CORBA Name Service also provides a BindingIterator object and a NamingContextExt object. The BindingIterator object allows a client application to obtain a specified number of bindings in each call. The NamingContextExt object provides methods to use Uniform Resource Locators (URL) and stringified names.
