Abstract: PROBLEM TO BE SOLVED: To secure the loose coupling among many processors included in a system and to evade the common use of the resources by starting the execution of a transaction in one of user application processes based on the data received from the end user terminals. SOLUTION: Many user application processes 116-2 to 116-N are distributed among the server computers. In a communication management process 112, the data are transferred between the end user terminals 102-1 to 102-J and a transaction router process 114 that is carried out by one of server computers. In the process 114, one of transactions kept in the standby states is carried out in one of processes 116-2 to 116-N based on the data received from the terminals 102-1 to 102-J.

Abstract: PROBLEM TO BE SOLVED: To distribute the calculation loads of a customer information control system over a set of loose coupled parallel processors and to provide an API (application program interface) provided with a transaction serialization control function. SOLUTION: A distributed computer system 100 is provided with plural end user terminals 102 and plural loose coupled server computers for not mutually sharing resources and many user application processes 116 are distributed to the server computers. A first server computer is allocated so as to tentatively store the queue of data recording. The respective user application processes 116 respond to the execution of a WriteQ TS instruction and store at least one piece of TS data for indicating specified data in a tentative storage file. Each TS data recording is provided with a primary key for indicating the position of recording in a specified tentative storage queue. The respective user application processes respond to the execution of a ReadQ TS instruction for specifying the tentative storage queue to retrieve the data and read at least one piece of the TS data recording from the tentative storage file.
