当前，随着信息技术成熟与发展，ORACLE数据库系统结构日益复杂，虽从一定程度完善、提高其使用性能，并扩展了其使用范围，但仍然存在诸多不稳定因素。本文结合ORACLE系统结构，从OFA自由结构、回滚段、运行机制、硬件以及OS等周边环境多方面对数据优化进行阐述，并制定出相应优化策略。%At present, along with the information technology development, ORACLE database system structure is becoming more and more complex, thoughimproving, from a certain degree to improve service performance, and expand its scope of application, but there are still many unstable factors. In this paper, combined with the ORACLE system structure, from the aspects ofOFA free structure, rollback segment, operational mechanism, hardware and OS environment to carry on the elaboration to data optimization, and formulate the corresponding optimization strategy.
