META-INFORMATION SHARING DISTRIBUTED DATABASE SYSTEM IN VIRTUAL SINGLE MEMORY STORAGE

摘要

Concerning scale out of a distributed database system requiring real-time update enabled by means of division among a plurality of database domains of the database system, adaptation to further scale out and higher performance thanks thereto are achieved. A large-scale database system is distributed among a plurality of database domains. In a multi-transaction requiring real-time update of database objects across the database domains, exchange and synchronization of meta-information about the multi transaction, such as status information, are performed, and the partition topology or the replication topology is applied to a database meta-information storage managing unit in a database meta-information management repository device. Thus, the multi-transaction is performed at a higher speed.
