If the determined buffer lock mode is more enough rather than the buffer lock mode which a current buffer has already obtained, the buffer installation request is immediately approved(S108). But if the obtained lock mode is less than the requested buffer mode or a currently loaded block version does not satisfy a requested version(S103, S104), a buffer lock is requested to a global lock manager(S105), and the buffer lock is waited for until receiving a block is successful(S106).
