使用RMAN來PDB執行完全恢復

可以對一個或多個PDB執行完全恢復而不影響其它為open狀態的PDB的操作。RMAN有兩種方法來恢復PDB:
.連線到CDB的root容器，然後使用restore pluggable database與recover pluggable database命令。這種方法能讓你使用單個命令來恢復多個PDB。

.連線到PDB並使用restore database與recover database語句，這種方法只能恢復單個PDB並且能讓你使用相同的命令來恢復non-CDB資料庫

使用RMAN恢復一個或多個PDB
1.啟動RMAN並使用有sysdba或sysbackup許可權的公共使用者連線到root容器

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

2.關閉你要執行恢復操作的PDB

SQL> alter pluggable database jypdb,testpdb close immediate;

Pluggable database altered.


SQL> select name,open_mode from v$pdbs;

TESTPDB                                                                                                                          MOUNTED

3.可選操作，使用configure命令來配置預設裝置型別與自動通道

4.執行restore pluggable database與recover pluggable database命令，下面的語句恢復 jypdb,testpdb

RMAN> restore pluggable database  jypdb,testpdb;
