Tuxedo Distributed Processing Clients

The Tuxedo Application Servers can be accessed by a variety of clients. These include:

• Clients that provide a uniform interface for application communication, transaction support (for example, XA), and management of Tuxedo data buffers using the Tuxedo Application to Transaction Monitor Interface (ATMI). These may be traditional CA Gen GUI clients, Java Web Clients, or user-written clients using CA Gen proxy (C, COM, or Java).

  For a CA Gen distributed application to exploit features provided by Tuxedo, the data that is exchanged is represented using the View32 data format of Tuxedo.

  By employing the View32 data representation, CA Gen applications can use the data dependent routing feature of Tuxedo. To accomplish data dependent routing, the Tuxedo TP Monitor environment is configured to route data to different servers based on the content of data contained in the View32 buffer. Data dependent routing is achieved without modifying the CA Gen generated application code by using the capability provided by Tuxedo.

  Additionally, Tuxedo Security is enabled through information provided by the user in the Tuxedo Configuration file (UBBCONFIG) and through making appropriate changes to a sample CA Gen runtime security user exit.

• Clients that use a Gen communications type of Gen or TCP/IP. Either of these clients needs to make use of the CA Gen Tuxedo Proxy Client (ieftuxcl). The Tuxedo Proxy Client provides a TCP/IP interface to the Tuxedo execution environment.

CA Gen clients that specify Gen as the communications type use the CA Gen Client Manager. The Client Manager can communicate with ieftuxcl directly or indirectly by using a CA Gen Communications Bridge.
