ORA-07217: sltln: environment variable cannot be evaluated.

出错原因：没有定义变量$BACKUP_HOME。

解决办法：将$BACKUP_HOME改成具体的值即可。

示例：

RMAN> run {

allocate channel c1 device type disk format '/home/oracle/rmanbk/level0/level0_%d_%s_%p_%T.bkp' connect sys/oracle@app1;

allocate channel c2 device type disk format '/home/oracle/rmanbk/level0/level0_%d_%s_%p_%T.bkp' connect sys/oracle@app2;

change archivelog all crosscheck;

backup archivelog all;

}

--这是在两个节点的rac环境下执行的。

--一定记得要分配通道，且有必要的话，前面加上命令：change archivelog all crosscheck;

否则，可能备份失败，报如下错误：

RMAN> backup archivelog log all;

RMAN> backup archivelog all;
