In a transaction processing system that includes a plurality of client processes coupled to a server process, the server process supports execution of transactions generated by the client processes. The server process includes, for each client process being served, one or more transaction message control mechanisms. Each transaction message control mechanism includes a named processing object that includes a name identifying the object. The named processing object also includes an input process that receives all transaction request messages naming the object and identifying the originating client process. The input process dispatches a transaction process for each transaction request message received from the respective client process. Each transaction process oversees transaction execution and receives transaction output. A transaction process provides a transaction output message for the originating client process. In a non-sync'd mode of operation, transaction processes may synchronously send transaction output messages to client processes. In a synchronized mode of operation, one transaction process at a time sends output messages under control of an output process in the named processing object. The transaction message control mechanisms provide a bi-directional transaction message flow between server and client processes.

Apparatus and method enabling a client to control transaction message traffic between server and client processes

A communication system includes a network of transaction management systems having the same or different operating system software versions. Each transaction management system includes an associated input device for generating a transaction request or message switch. The transaction requests and message switches generated by a particular input device can be executed by the transaction management system associated with the device, and alternatively by remote transaction management systems in the network. To provide for remote execution of transaction requests and message switches, the system includes means for generating transaction request messages and message switch messages that have prefixes which can be dynamically extended as required for use by the appropriate remote transaction management system, without requiring upgrading the software of the remote system.
