Linux 下 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：

### backup.sh ###
