PROBLEM TO BE SOLVED: To provide an automatic on-line environment changing system by which a terminal to be used in a system while the system is working is added or erased during on-line system working. SOLUTION: When the data processing means 12 of a computer 11 receives change indicating data with the input of a change required date in the system from the data transmitting means 151 of a computer 14, it is preserved in the change indication data part 134 of a storage device 13 by a data processing means 12. The data processor 12 which is started at every fixed time changes a system environment table 131 developed in the storage device 13 when the system on the computer 11 is started, changes a system environment definition during the on-line system working and the logical definition of the system on the computer 11 and shifts data after the end of a processing to the change history data part 135 of the storage part 13.
