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

Recovery Manager: Release 12.2.0.1.0 – Production on Mon Dec 11 16:56:58 2017

connected to target database: JY (DBID=979425723)
connected to recovery catalog database
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;

NAME OPEN_MODE
——————————————————————————————————————————– ———-
PDB$SEED READ ONLY
JYPDB MOUNTED
TESTPDB MOUNTED

SQL>
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;
