使用expdp备份数据库

Question

当我使用此语句备份oracle时:

EXPDP userid=scott/tiger@orcl directory=DATA_PUMP_DIR dumpfile=%filename%.DMP

它有错误:

Ora-39002:The operation is invalid
Ora-3970:can not open the log file
Ora-39087:directory name DATA_PUMP_DIR is invalid

当我跑:

select * from dba_directories;

DATA_PUMP_DIR是

D:\app\Administrator\admin\orcl\dpdump\

更重要的是,我自己创建了目录.它仍然提供相同的错误,我非常确定目录存在.

您需要授予用户对目录的读写权限以进行备份.(假设您拥有所有权限)

GRANT read, write ON DIRECTORY data_pump_dir TO scott;
