Windows Oracle 10g到Linux Oracle19c RAC的升级实现

Implementation of Upgrading from Windows Oracle 10g to Linux Oracle 19c RAC

目的探讨Oracle数据库系统跨版本跨平台升级实现的可行性方案。方法从制订方案、方案实施、数据验证方面,详细介绍了Oracle数据库升级的具体实施方法与技术要点。结果实现Oracle数据库从10g for Windows到19c RAC for Linux的跨多版本系统升级,系统稳定运行。结论采用数据泵(expdp/im‐pdp)工具,通过建立中间库的方式升级,安全可靠,可操作性强,对相同功能需求具有参考借鉴价值。

Objective To discuss the feasible plan of the implementation of the cross-version and cross-platform upgrade of the Oracle database system.Methods The specific implementation methods and technical points of the upgrade of the Oracle database are introduced in detail from the aspects of the plan formulation,plan implementation and data verification.Results The upgrade of the cross-muti-version system of the Oracle database from 10g for windows to 19c RAC for linux is realized,and the system runs stably.Conclusion The data pump(expdp/impdp)tool is used,and the upgrade is made by establishing intermediate libraries,which is secure and reliable,has strong operability,and has reference value for the same functional requirements.
