   Using the BEA Tuxedo TOP END Domain Gateway

This sample program, which is an extension of Example 1 in the core BEA Tuxedo DMCONFIG(5) reference page, shows five Bank Branch domains communicating with a Central Bank branch. Three of the Bank Branches run within one BEA Tuxedo system domain (TDomain). The fourth Branch runs under the control of another TP domain and uses OSI TP to communicate with that domain. Example 1 has been extended to include a TEDG with a single connection to a BEA TOP END system. The BEA TOP END system is running a banking application that offers services needed by the BEA Tuxedo application. Conversely, certain BEA Tuxedo services need to be available to BEA TOP END clients. A simple queuing example is also included.

The BEA TOP END system, BANKSYS, offers a single product called EBANK. The following table lists the functions available for the EBANK product.
