Technique for log records management in database management system

Abstract

Disclosed is a computer program stored in a computer-readable storage medium including encoded commands according to an exemplary embodiment of the present disclosure. When the computer program is executed by one or more processors, the computer program allows the one or more processors to perform a method for managing undo information in a database management system (DBMS). The method may include: forming undo information corresponding to an update request by a first transaction in response to the update request by the first transaction in the database management system (DBMS); determining an undo memory chunk to be allocated to the undo information from an undo memory pool on a memory, the undo memory chunk having a variable size; and maintaining the undo information on a space of the memory by using the determined undo memory chunk.
