Oracle备份脚本（RMAN/EXP）

环境：
 
OEL+Oracle 11.2.0.1
 
ORACLE_SID=orcl2
 
创建如下目录：
 
[root@DBA2 /]$ mkdir /backup
[root@DBA2 /]$ mkdir /backup/0
[root@DBA2 /]$ mkdir /backup/1
[root@DBA2 /]$ mkdir /backup/2
[root@DBA2 /]$ mkdir /backup/3
[root@DBA2 /]$ mkdir /backup/4
[root@DBA2 /]$ mkdir /backup/5
[root@DBA2 /]$ mkdir /backup/6 

更改属主：
 
[root@DBA2 ~]# chown -R oracle:dba /backup/

脚本内容如下：
