使用RMAN来PDB执行完全恢复

可以对一个或多个PDB执行完全恢复而不影响其它为open状态的PDB的操作。RMAN有两种方法来恢复PDB:
.连接到CDB的root容器，然后使用restore pluggable database与recover pluggable database命令。这种方法能让你使用单个命令来恢复多个PDB。

.连接到PDB并使用restore database与recover database语句，这种方法只能恢复单个PDB并且能让你使用相同的命令来恢复non-CDB数据库

使用RMAN恢复一个或多个PDB
1.启动RMAN并使用有sysdba或sysbackup权限的公共用户连接到root容器

[oracle@jytest1 ~]$ rman target/ catalog rco/xxxxx@jypdb_173

2.关闭你要执行恢复操作的PDB

SQL> alter pluggable database jypdb,testpdb close immediate;

Pluggable database altered.


SQL> select name,open_mode from v$pdbs;

TESTPDB                                                                                                                          MOUNTED

3.可选操作，使用configure命令来配置缺省设备类型与自动通道

4.执行restore pluggable database与recover pluggable database命令，下面的语句恢复 jypdb,testpdb

RMAN> restore pluggable database  jypdb,testpdb;
