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.

Abstract: PROBLEM TO BE SOLVED: To distribute the calculation load of a customer information control system over a pair of loose coupling parallel processors and to impart API transaction start and cancel function. SOLUTION: A distributed type computer system 100 includes plural end user terminals 102 and plural loose coupling server computers which do not share resources with each other. Many user application process 116 are distributed to these server computers. The transaction start table stored in a first server computer stores the transaction start data showing the transactions which are requested to be executed by the user application processes 116. A start condition in the value showing the earliest time when the execution of the requested transaction should be started. When the user application processes 116 execute start transaction function, transaction start records are generated and the records are stored in the transaction start table.

Abstract: PROBLEM TO BE SOLVED: To specify an Enq record to an application process by storing it in an Enq table on a 1st server computer among server computers without reference to which of the server computer executes one Enq instruction. SOLUTION: An end user terminal 102-1 sends and receives data to and from a server system 110 through a communication management process 112. The communication management process 112 performs the route specification of a data message between a terminal and a transaction router process 114. The transaction router process 114 sends the corresponding transaction record to a link manager process 115, which selects a user application process 116-2 and stores it in the Enq table on the 1st server computer among the server computers without reference to which server computer executes one Enq instruction.
