迁移方案4-3:映像副本(copy)与可更新增量映像副本(IUIC)的跨主机迁移使用案例—(最适合fs-asm迁移,也可以实现跨主机迁移)
一、跨主机迁移思路
1. 源库switch logfile,checkpoint,shutdown;
2. 源库startup restrict;shutdown immediate;startup mount;
3rman target / ;backup as copy database;
4,.新库restore spfile, restore controlfile, catalog start with ''备份片, startup mount; switch database to copy; alter database open;
5, 新库重建控制文件。
因为源库多次shutdown,open。并且在mount下备份image copy,所有在switch to copy 之后,省略了recover步骤,也不用涉及归档日志。
