Message-efficient client transparency system and method therefor

A method of controlling a transaction processing system having a client application, a client transparency mechanism, first server application, a first server transparency mechanism, and a database system, comprising the steps of:

• sending a request having a unique identification from the client application through the client transparency mechanism to the first server transparency mechanism, the first server transparency mechanism connected to the first server application;
• starting a transaction at the database system by the first server transparency mechanism;
• sending the request from the first server transparency mechanism to the first server application;
• processing the transaction in the first server application and the database system;
• placing the unique identification and a corresponding result of the transaction processed by the first server application to the database system;
• ending the transaction between the database system and the first server transparency mechanism;
• committing the transaction in the database system by the first server transparency mechanism;
• providing an indication from the first server transparency mechanism to the client transparency mechanism that the transaction was committed in the database system;
• and
• providing the indication from the client transparency mechanism to the client application.

A transaction processing system comprising:

• a client application for providing a transactional request and receiving a transactional reply;
• a client transparency mechanism connectable to the client application for transmitting messages to and from the client application, and for providing messages related to failures in the transaction processing system;
• a first server transparency mechanism connectable to the client transparency mechanism for transmitting messages to and from the client transparency mechanism;
• a first server application connectable to the first server transparency mechanism for processing the transactional request;
• and
• a database system connectable to the first server application for processing transactions therefrom, the database system providing failure indications on failure thereof and including a rollback and restarting mechanism;
• the client transparency mechanism including a mechanism responsive to and for providing instructions related to failures in the first server application, the first server transparency mechanism, and the database system, and providing failure recovery capability independent of the client application;
• the first server transparency mechanism including a mechanism responsive to and for providing instructions related to failures in the database system, the first server transparency mechanism providing a unique identification and a corresponding result for the transaction.
