Oracle 12c 多租户 CDB 与 PDB 备份

一、  CDB 备份

1.1  只备份CDB

只备份CDB数据库需要具有SYSDBA或SYSBACKUP权限用户连接到CDB的root环境下，执行backupdatabase root命令即可完成对CDB的备份，方法如下：
[[email protected] ~]$ rman target / 
[[email protected] ~]$ mkdir /home/oracle/rmanback/
RMAN> backup database root format=‘/home/oracle/rmanback/db_%d_%U‘; 
RMAN-03002: failure of backup command at 05/10/2017 23:14:58
RMAN-06817: Pluggable Database CDB$ROOT cannot be backed up in NOARCHIVELOG mode.
说明： 只备份 CDB 需要数据库在归档环境下，自行把数据设置为归档模式。
RMAN> select name,log_mode from v$database;

--------- ------------
ANDYCDB   ARCHIVELOG

1.2.  备份整个CDB及其下面的所有PDB
备份整个CDB数据库及其下面的所有PDB类似于非CDB数据库方法相同，使用具有SYSDBA或SYSBACKUP权限用户连接到CDB的root环境下面，然后执行backupdatabase命令即可完成整个CDB的备份，方法如下： 
RMAN> backup database format=‘/home/oracle/rmanback/db_%d_%U‘;

二、 备份 PDB

1.1.  备份单个和多个PDB
在CDB中允许备份一个或多少PDB数据库（如果要备份多个pdb,只需在备份命令后面跟上多个你想备份的pdb实例的名称，如下backup pluggable database pdb1,pdb2; ），备份一个PDB数据库可以通过以下两个方式备份：
注意：如果没有开启归档模式，单独备份 CDB 或者是 PDB 都会报ORA-19602: cannot backup or copy active file in NOARCHIVELOG mode
方式一：在CDB根（root）使用BACKUP PLUGGABLE DATABASE命令备份一个或多个PDB数据库。 
[[email protected] ~]$ rman target / 
RMAN>  backup pluggable database pdb01;

备份默认在 闪回恢复区里。

方式二：在PDB中使用BACKUP DATABASE备份当前连接的PDB数据库，前提条件是需要配置好TNSNAMES.ORA文件。 
[[email protected] ~]$ rman target sys/[email protected]:1521/pdb01
connected to target database: ANDYCDB:PDB01 (DBID=2550500229) 
RMAN> backup database format=‘/home/oracle/rmanback/db_%d_%U‘;

Oracle 12c 多租户 CDB 与 PDB之 shared undo 与 Local undo 切换

undo 在12C R1版本中只支持Global Shared Undo模式, 所有container共享一个UNDO表空间, 目前保留这种模式只是为了升级过渡, 在12C R2引入了PDB Local UNDO模式,每个container都有自己的UNDO 表空间, 对于RAC是每个实例每个container都有自己的UNDO表空间, 这也正是推荐的.在DBCA时会有local undo选项,且默认勾选. local undo 模式的好处:1.减少undo表空间的争用,同时方便拔插 2.只有使
