汉译英,计算机方面的一小段文字
数据迁移是Oracle数据库管理维护的重要内容,为了解决数据库迁移过程中迁移数据量大,宕机时间长,数据库平台版本不同等因素造成的迁移失败的问题,本文提出一种类似prebuilt mv的trigger数据迁移方法.该方法可以在线迁移100G以上的大型数据库,还可以解决高可用环境中数据迁移难以解决的最短时间切换,跨平台迁移,跨版本迁移等问题.试验结果证实了该方法的有效性.
Data migration is an important part of the Oracle database management and maintenance, in order to solve the migration database migration process large volumes of data, downtime for a long time, different versions of the database platform migration issues such as the failure of factors, this paper presents a similar prebuilt mv the trigger data migration methods. This method can migrate 100G more large online database, you can also solve the shortest period of time in a highly available environment difficult to solve switched data migration, cross-platform migration, cross-version migration and other issues. The test results demonstrate the effectiveness of this method.
