SYSTEM AND METHOD FOR STORING ENDURABLE AND NON-ENDURABLE QUEUE DATA

摘要

PURPOSE: To provide a method in order to store the data (persistent data) which need persist even after a system fault and the data (nonpersistent data) which need not persist after the system fault into a single queue. CONSTITUTION: The pages of a memory are distributed to the storage areas prepared for only the persistent and nonpersistent data respectively. The details of change of only the persistent data are recorded in a log. If a system fault occurs, a queue can recover only the persistent data by checking every page and need not scan each item in pages.
