Transaction Design Consideration

From the programmer's perspective, transactions involving the TEDG and a remote system function are handled the same way any transactions are handled in the local system. The only consideration to keep in mind when designing transactions for a configuration that includes BEA Tuxedo and BEA TOP END systems is that two-phase commit processing cannot be optimized as much as it can be optimized for transactions that involve only one system. Therefore, transactional requests involving a remote system have a slightly higher cost to commit. When designing your application, you should consider the number of intersystem requests likely to be made and the potential effect of these requests on performance.
