1.1 准备
1.1.1 确认spfile备份文件
可以通过 list backup of spfile 来查看，也可以通过rman的备份日志来查找。下面是示例：
RMAN> list backup of spfile;

通过日志查找:

1.1.2 恢复spfile并修改
rman target / restore spfile to pfile from '/orabackup/backup/rmanbak/0511/level1_BOSS_20200511_29398_1.bak';
然后修改pfile 文件，调整一些必要的参数。比如内存分配，比如去除RAC配置等。
1.1.3 启动到nomount状态
目标环境实例需要启动到nomount状态。

1.1.4 查看截止SCN
通过 list backup of archivelog all; 命令在原库中查看全备的中，归档的最后的SCN号。 我们需要告诉RMAN, 恢复到此SCN号为止。不然会报RMAN-06054: media recovery requesting unknown log: thread N seq xxxxx lowscn xxxxxxxx 示例如下:

1.1.5 确认控制文件备份
通过 RMAN 命令 list backup of controlfile; 在原库中查找对应的控制文件。 本次操作，需要使用控制文件备份信息如下:

Control File Included: Ckp SCN: 38011697387 Ckp time: 10-MAY-20
如果原库不可用，可在rman备份日志中通过control关键词查找，示例如下:

1.1.6 准备全量恢复脚本
rman脚本：
#!/bin/sh rman target / <recovery0510.log restore controlfile from '/recovery/0510/level0_BOSS_20200510_29361_1.bak'; alter database mount; catalog start with '/recovery/0510/' noprompt; set until scn 38021702290;

将以上内容保存到recovery.sh
1.1.7 准备增量恢复脚本
此步骤可能需要执行多闪。因此需要多次确认SCN号。
catalog start with '/recovery/0511/' noprompt; set until scn 38031802340; recovery database;
1.2 恢复数据
1.2.1 执行全备恢复
本次恢复，并没有从备份文件中恢复spfile, 执行上面的rman 脚本。/sh recovery.sh/ 观察rman 日志,部分内容如下：

看到最后, 出现错误提示:RMAN-06054 , 说明,备份的归档在恢复后，仍不能保证数据的一致性。
1.2.2 执行增量恢复
将备份数据发送到目标环境:
scp -r /orabackup/backup/rmanbak/0511 [email protected]:/recovery/
临时生产环境中，需要多次恢复。
catalog start with '/recovery/0511/' noprompt; recover database;
1.2.3 重建redo
需要确认控制文件中的redo 信息与恢复后的文件相匹配，否则无法open database.
set lines 32767 pages 5000 col status for a8 col type for a7 col member for a64 select a.inst_id,a.thread#,a.group#,a.sequence#,a.archived,a.status,b.type,b.member from gv$log a ,gv$logfile b where a.inst_id = b.inst_id and a.group# = b.group#;
结果:
INST_ID THREAD# GROUP# SEQUENCE# ARC STATUS TYPE MEMBER

1 2 2 11561 YES INACTIVE ONLINE +DGDATA/boss/onlinelog/group_2.379.997111039
重建redo:
alter database rename file '+DGDATA/boss/onlinelog/group_3.380.962034729' to '/oradata/redo03.log'; alter database rename file '+DGDATA/boss/onlinelog/group_1.378.962034643' to '/oradata/redo01.log'; alter database rename file '+DGDATA/boss/onlinelog/group_2.379.997111039' to '/oradata/redo02.log'; alter database rename file '+DGDATA/boss/onlinelog/group_4.381.997111077' to '/oradata/redo04.log'; alter database clear unarchived logfile group 1; alter database clear unarchived logfile group 2; alter database clear unarchived logfile group 3; alter database clear unarchived logfile group 4;
在这里需要注意, 执行rename file 的时候可能会报错:
ERROR at line 1: ORA-00600: internal error code, arguments: [kgeade_is_0], [], [], [], [], [], [], []
无需理会，因为原文件与目标文件都不存在。只要执行后，控制文件中的内容被更新即可。如:
SQL> alter database rename file '+DGDATA/boss/onlinelog/group_3.380.962034729' to '/oradata/redo03.log';
alter database rename file '+DGDATA/boss/onlinelog/group_3.380.962034729' to '/oradata/redo03.log'
ERROR at line 1:

2 修改IP
因为原来的库是RAC， 应用连接数据库的时候配置的IP 都是VIP。 为了减少应用运维修改配置的工作量,在临时生产环境中 启动vip 地址。
- NOTE
- 原库停止后，再在临时生产库上添加IP。否则会出现IP冲突。
