摘要
随着数据库在生活中各个领域中的广泛应用,数据库产品也层出不穷。其中,ORACLE数据库产品在整个数据库产品的应用中占据50%,并且有不断上升的趋势。可是,随着数据库数据量的增大、并发用户数量增多,系统常常出现吞吐量降低,响应时间延长等性能问题,怎样有效优化、改善数据库性能,突破系统瓶颈,是保证Oracle数据库高效运行的基础。Oracle数据库系统性能优化、调整是一项复杂的系统工程,贯穿于系统的整个生存周期中。
With the wide application of the database in the life of every field,database products also emerge in an endless stream.Among them,ORACLE database products occupy 50% in the whole database products,and there is a rising trend.However,with the increase of the amount of data in the database,the increase in the number of concurrent users.System often appears low throughput,extension of response time and other performance problems.How to effectively optimize,improve database perfor mance,breakthrough the bottleneck of system,is to ensure efficient operation of the Oracle database.Oracle database performance optimization,adjustment is a complicated system engineering,runs through the whole system life cycle.
