海量地理国情普查数据分布式存储研究

Research on Distributed Storage of Massive Geographical Conditions Census Data

针对地理国情普查成果数据量大、复杂且多样化、管理难度大、应用效率低等特点,提出了一种基于ISCSI构建ORACLE RAC数据库和GlusterFS分布式文件系统来管理地理国情普查数据的方法。实验结果表明,该方法能够充分利用普通的硬件和网络资源来构建数据存储环境,保障地理国情普查数据库快速稳定地运行,并且能够无缝地扩展存储资源。

Aiming at the large,complexity,diversity,difficulty management and low efficiency on application of geographical conditions census data,we provided a method of managing the geographical conditions census data using Oracle RAC database and GlusterFS distributed file system based on ISCSI.The application results show that this method can make full use of the common hardware and network resources to build the data storage environment,guarantee fast and stable operation of the geographical conditions census database,and extend storage resources seamlessly.
