Oracle Tuxedo CORBA provides a set of objects for helping the client work with the Tuxedo CORBA environment; the objects enable client applications to easily log on to a Tuxedo CORBA environment, invoke CORBA objects, and start and end transactions. Like the server-side TP Framework component, these objects interact with the Tuxedo CORBA services.

Here is what these objects do for application clients:

Bootstrap object

The Bootstrap object provides references to the Tuxedo CORBA objects in a Tuxedo CORBA application. An application client can connect to multiple Oracle Tuxedo CORBA applications using different Bootstrap objects. One of the first things that an application client does after startup is to create a Bootstrap object by supplying the host and port number of the IIOP Listener. After the application client contacts an IIOP Listener, the Listener assigns an IIOP Handler to the application client, and the Boostrap object establishes a communication link with the assigned IIOP Handler. The Bootstrap object also provides references to well-known objects that application clients use, such as TransactionCurrent, SecurityCurrent, InterfaceRepository, and FactoryFinder.

CORBA OTS TransactionCurrent object

The CORBA OTS TransactionCurrent object coordinates transaction demarcations with the transaction coordinator.

SecurityCurrent object

The SecurityCurrent object gets the application client’s security credentials from the Security Service. The SecurityCurrent object registers the certificate with the IIOP Handler, which uses the certificate to permit or deny invocations.
