Oracle群集件Clusterware的机制研究与性能分析

Mechanism and Performance of Oracle Clusterware

群集件是整个数据库集群的核心模块,用以管理和协调整个集群环境中的硬件资源,并为数据共享存储和并发访问控制提供支持。本文详细论述了Oracle群集件Clusterware的工作原理,并与其他两个主流的数据库集群(SQLServer Cluster和MySQL Cluster)进行对比,分析其性能上存在的优势与不足,从而为用户依据自身需求选择合适的集群解决方案提供指导。

Oracle Cluster extends Oracle Database so that you can store,update,and efficiently retrieve data from multiple instances on different servers at the same time.As the core of cluster,Oracle Clusterware provides shared-disk storage architecture and support high performance concurrency operations.Compared with the SQL Server and MySQL solution,we try to analyze the advantages and disadvantages of Oracle Clusterware.We believe these results will help customers to choose the right solution.
