江苏理工学院毕业设计说明书(论文) Oracle在Linux平台的 Data Guard应用 摘 要：在这样一个经济迅猛发展的时代，数据的批处理量也随着直线上升。这些数据可以说是一个企业或者政府的命脉，一旦丢失或者损坏所带来的损失就是不可估量的。为了解决此类问题提高高可靠性和可用性就成为数据库目前迫切需要解决的一大难题。 本次课题主要就是Oracle针对数据安全所研发的一项技术，也是源于我在13年暑期校外的实践培训，那时开始接触并对Oracle数据库相关知识，其中就包涵了Oracle数据库是如何容灾的。系统容灾备份工作对DBA（数据库管理员）的依赖性很高，不但增加对DBA工作上的压力同时精神上也承受着很大的负担，不能完全保证数据的安全性。Oracle数据库的高可用DG应用（下文所有Data Guard均简称DG）就很好解决了这个问题，同时这个环境也减轻了DBA的工作量，它的高可用不但从安全的角度达到了要求而且它的低成本也是一个很大的亮点。 本文主要介绍了在Linux平台使用Oracle数据库进行数据保护，具体实施过程和细节以及它运行的软件环境，一步一步循序渐进。详细叙述安装流程，记录了这个过程中所需的一系列的问题与对策；为配置好环境制定相关测试流程，并记录相关内容以备查阅。 关键词: 数据安全，系统容灾，数据保护 PAGE \* MERGEFORMAT PAGE \* MERGEFORMAT 2 Oracle Data Guard applications on Linux platform Abstract: In such an era of rapid economic development, batch amount of data along with straight up. These data can be said to be the lifeblood of a business or government, once the loss or damage is caused by the loss immeasurable. To solve such problems to improve the reliability and availability of high current database has become an urgent need to address a major problem. The main topic is an Oracle technology developed for data security, also stems from my 13 years of hands-on training in the summer off-campus, then came into contact with and knowledge of the Oracle database, which will bear the Oracle database is how disaster recovery. System disaster recovery work high on DBA (database administrator) dependence, not only increase the pressure on DBA work while mentally bear a great burden, can not guarantee the security of data. DG applications highly available Oracle database (hereinafter referred to were all Data Guard DG) on a good solution to this problem, this environment while also reducing the workload of the DBA, it's not only from a safety point of view high availability meets the requirements and it is also a great low-cost highlights. This paper describes the data in the Linux platform using Oracle database protection, and details of the specific implementation process as well as its software envi
