PROBLEM TO BE SOLVED: To dynamically change a cut synchronous transaction with a simple operation without stopping the operation of a system in a cluster-type computer system which is constituted of plural host computers and which can be on-line- accessed. SOLUTION: When the cut synchronous transaction is changed in the host computer 12a or 12b of the cluster-type computer system 10, cut synchronous transaction information registration means 22a and 22b store the changed contents in a data storage device 18 which the plural computers share in the form of the update of cut synchronous transaction information. When the respective host computers receive a cut request from terminals 16a and 16b, cut synchronous transaction information retrieval means 24a and 24b retrieve cut synchronous transaction information and selects the cut transaction to be started in accordance with the retrieved result. |
