Linux 平台下 RMAN 全备 和 增量备份 shell 脚本
http://blog.csdn.net/tianlesoftware/archive/2010/07/16/5740630.aspx
在执行脚本之前，先修改几个参数值：
1. DB 参数：
修改控制文件的保存时间，从默认的7天改成14天
SQL> show parameter control
SQL> alter system set control_file_record_keep_time=14 scope=both;
2. RMAN 参数：
开启控制文件的自动备份，开启之后在数据库备份或者数据文件（比如添加数据文件）有修改的时候都会自动备份控制文件和spfile文件。
RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
3. 备份策略根据自己的系统决
我这里是周日做0级备份。周四1级备份，其他2级备份。
4. 备份脚本如下：
