PROBLEM TO BE SOLVED: To provide a technology capable of: deriving a suitable locking form in data base processing; and setting a dynamically suitable locking form to an O/R mapping framework. SOLUTION: A tracing log and a mapping table in a first storage are referred to and analyzed. An operation, a program executed based on the operation, and a tracing log of the program are associated and stored in a second storage. The operation, a program executed based on the operation, and a tracing log of the program which are thus stored are referred to. The tracing log of the operation is evaluated for each locking form and the locking form to be used by a program executing apparatus is decided. The decided locking form is set to a plurality of program executing apparatus. COPYRIGHT: (C)2009,JPO&INPIT
