Abstract
A flexible distributed processing system capable of dealing with sophisticated conditions for selecting a server process. In the system, each of the services provided by all server processes is registered in the service manager in correspondence with an executability condition for judging whether each service is executed, such that the service manager selects one of the server processes which is providing the desired service indicated by the inquiry transmitted from the client process and which is judged to be executable according to the executability condition registered at the service manager, and the client process requests the desired service the selected one of the server processes. The system can utilize a transaction processing for a nested transaction in which a commit processing for the processes of the sub-transactions which are incapable of executing the nested transaction, is completed concurrently with a completion of the commit processing for the top level transaction.
