Methods and systems consistent with this invention link a program module, which implements dynamic linkage to an external function and executes the external function. Such methods and systems replace a function name described in a header portion of a program module and a function name to be referred to by the program module with other names, and link functions having the same names as the replaced function names and executing the linked functions in place of an original function.

Method of changing a dynamic link library function efficiently and a computer system for executing the same

When the item appearance frequency count up section counts up the appearance frequency of an item in a shared memory space on the basis of transaction data, a count up log transfer section receives the count up log recorded by a count up log recording section and transfers it to other nodes. A count up log receiving section transfers the count up log transferred from each of the remaining nodes to a count up log reflecting section. The count up log reflecting section, which has received this count up log, reflects its contents in the appearance frequency of the corresponding item in the shared memory space.
