Abstract

A program is disclosed that the volume of DBMS (DataBase Management System) log produced for database reorganization can be significantly reduced. By logging the logical information for the database physical changes made through the reorganization process to dissolve the storage fragmentation, it eliminates the ‘user data’ content from the database update log records.
