<p>According to the present invention, a transaction processing system is provided for executing transactional processes representing transactions, wherein the transaction processing functionality is integrated within a reduced kernel operating system such as a microkernel or nanokernel operating system. The system of the invention comprises a processor for executing the processes, and a main memory accessible to the processor for storing programs, including a reduced kernel operating system, to be executed by the processor. The main memory of the system has a supervisor area (510) where operating system functions forming the reduced kernel are stored, and a user area (520) where user programs and other operating system functions are stored. According to the present invention, a data structure (565, 570) is stored in the supervisor area (510) of main memory for storing information about the processes to be executed by the processor, and additionally the following operating system functions are stored in the supervisor area (510) of main memory: a scheduler (560) for applying a scheduling policy to determine the order in which processes identified in the table are provided to the processor for execution; a concurrency control manager (550) for managing the transactional processes to be executed by the system; and a message passing system (540) for passing messages between processes being executed by the processor, and for notifying the concurrency control manager (550) of any messages received by the message passing system from the transactional processes.</p> |
