RMAN-00571: ===========================================================
RMAN-03009: failure of backup command on cha1 channel at 01/20/2010 12:28:23
ORA-19504: failed to create file "/oracledir/mybackup/full_08l3ubv6_1_1_20100120"
ORA-27040: file create error, unable to create file
Linux Error: 2: No such file or directory

错误原因：需要在/oracledir文件夹下创建mybackup文件夹，并给出用户写权限：
[oracle@xy oracledir]$ chown oracle:oinstall /oracledir
[oracle@xy oracledir]$ chmod 777 /oracledir
[oracle@xy /]$ cd oracledir/
[oracle@xy oracledir]$ mkdir mybackup
[oracle@xy oracledir]$ chmod 777 mybackup


再次执行RMAN备份命令：
RMAN> run{allocate channel cha1 type disk;
2> backup
3> format '/oracledir/mybackup/full_%U_%T'
4>  database;
5> release channel cha1;}

allocated channel: cha1
