使用RMAN备份Tablespace

1、查看Tablespace信息

SQL> desc dba_tablespaces

SQL> select tablespace_name,contents from dba_tablespaces;

TABLESPACE_NAME                CONTENTS
------------------------------ ---------
SYSTEM                         PERMANENT

EXPIMP                         PERMANENT

7 rows selected.

 2、执行tablespace(example,users)备份

RMAN> backup tablespace example,users format '/u01/arcerzhang/tb_exampleAndUsers_%U';
