ABSTRACT:
A method of pre-processing a transaction within an application program in a distributed data processing system. The system comprises a network, a first computer system, a second computer system and a communication channel between the computer systems for communicating over the network. Each of the computer systems comprises a processor, memory for storing transactions and an operating system for executing the application program. Firstly, the first computer system sends a transaction, which is received by the second computer system. Next, the second computer system determines whether the transaction is current. If the transaction is current, the second computer system forwards the transaction for processing. If the transaction is not current, the second computer system sends software to the first computer system, in order to update the transaction. Once the first computer system has received the software, it applies the software to the transaction.
