Using the BEA Tuxedo TOP END Domain Gateway

The TOP END Domain Gateway (TEDG) provides support for fully transactional message passing and queuing between BEA TOP END and BEA Tuxedo systems. Transactions may be initiated by either system.

The TEDG does the following:

Serves as the transaction coordinator between the systems and adjusts to the requirements of each system.
Maps transaction IDs and logs the state of transactions as required for recovery.
On recovery after a failure in a TEDG node or TEDG process, the TEDG examines the transaction log and takes action to complete transactions that have reached the "prepared" state. Any transactions that are still in progress are aborted or rolled back.
