RMAN备份控制文件错误，RMAN-03009,ORA-19504,ORA-27040

使用RMAN备份控制文件报错：

上面提示没这样的文件和目录，但经过确认确实是存在目录和文件的已经权限都正确，很奇怪！！，再看看配置

RMAN> show all;

仔细的看看上面的保存路径， ' /backup/contorlfileback/control%F'; 好像/前多了一个空格，会不会是这里的问题？？，如是去掉空格

RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/backup/contorlfileback/control%F';

old RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO ' /backup/contorlfileback/control%F';
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/backup/contorlfileback/control%F';
new RMAN configuration parameters are successfully stored

备份成功了，还真是多了一个空格的问题，所以提醒各位不要粗心大意，犯了这样的错误！！！
