ORA-27040: file create error, unable to create file

问题描述：在搭建DG复制文件到备库时，出现以下异常： RMAN> duplicate target database for standby from active database; 异常信息如下： ORA-19504: failed to create file "/u01/app/oracle/fast_recovery_area/orcl151/control02.ctl" ORA-27040: file create error, unable to create file Linux-x86_64 Error: 2: No such file or directory 异常原因：控制文件control02.ctl创建失败. 解决方案：备库中手动创建/u01/app/oracle/fast_recovery_area/orcl151目录，注意权限与/u01/app/oracle/oradata/orcl151保持一致，并确保备库数据库处于nomount状态，主备库监听和TNS配置无问题，再去执行duplicate操作，执行无异常发生. 以下为执行过程： RMAN> duplicate target database for standby from active database;
