目的：将“军卫一号”操作系统从32位Windows 2000升级为64位Windows 2003，Oracle数据库从8.17升级为10g （64位）。解决服务器负载过重及并发用户连接数过多导致数据库无法连接的问题。方法：在升级测试的基础下，完成数据迁移，建立RAC，部署Data Guard。结果：实现数据库升级，系统运行速度大大提高，使“军卫一号”数据库达到高效和高可用。结论：将数据库从32位Oracle8.17升级为64位Oracle10g RAC是一个投入低、效益高的方法。“,”Objective:“No.1 Military”operating system upgrade from a 32-bit Windows 2000 64 Windows 2003, Oracle Database 10g (64 bit) from the 8.17 upgrade. Solve the server is overloaded and concurrent users to connect too many result in the database can not connect. Method:Upgrade testing on the basis of completion of data migration, the establishment of the RAC, to deploy a Data Guard. Results: database upgrade, the system is running much faster, “No.1 Military” database to achieve high efficiency and high availability. Conclusion:The database from 32 Oracle8.17 upgraded to 64 Oracle10g RAC is an investment in low-effective way.
