本文主要描述了Oracle数据库自动备份的具体实现步骤，具体内容请参考下文：
错误提示1：
message file rman.msb not found
verify that oracle_home is set properly
...... |
错误的主要原因：
自动执行的不能够识别相应的命令，需要在自动备份脚本中显式的声明Oracle的环境变量。
错误提示2：
standard in must be a tty
...... |
错误的主要原因：
不能在cron使用su或者管道等操作，必须将su命令移动到相关的shell脚本中。
错误提示3：

rman-00556: could not open cmdfile "backup_ar.rcv" ...... |
错误原因：
需要在cmdfile中指明绝对路径，不能因为shell脚本调用的cmdfile是在同一个目录下就可以直接使用文件名或者直接使用./
正确示例代码：
1、#cron文件
0 12,18 * * * /home/oracle/bak_sh/backup_ar.sh |
#表示每天12,18点对数据库归档日至进行全备份
2、入口shell文件，文件名：backup_ar.sh
export oracle_home=
/home/u01/app/oracle/oracle/product
/10.2.0/db_1export oracle_sid=testexport
lang=en_us.utf-8/home/u01/app/oracle
/oracle/product/10.2.0/db_1/bin/rman cmdfile = backup_ar.rcv |
3、rman备份脚本
connect target /connect catalog rman/rman
@rmanrun{allocate channel d1 device type
disk;sql "alter system archive log current";
