invalid value for parameter, 'directory'

问题

I am trying to import a datadump using impdp utility and who command is as follows:

IMPDP project/project DIRECTORY=e:\_workline\workspace\rfc_16012014\project_staging DUMPFILE=project_staging.dmp LOGFILE=project_staging_log.log;

But i get this error on running this command:

UDI-00014: invalid value for parameter, 'directory'

However the value passed to DIRECTORY paramter is correct as in if i paste the given path in i.e. e:\_workline\workspace\rfc_16012014\project_staging in the explorer window it will take me to the intended directory.

I hope the case of path string doesnt matter? e:\ and E:\ are same?

Can anyone please help with this?

回答1:

You need to create a directory in the database instead of pointing the physical directory path for datapump export and import.

Assuming that you have the necessary privilege to create a directory

CREATE OR REPLACE DIRECTORY <directory_name> AS 'e:\_workline\workspace\rfc_16012014\project_staging';

Then grant permission to user to read and write on that directory,

GRANT READ, WRITE ON DIRECTORY <directory_name> TO project;

Mention the created directory name into your Import command and try,

IMPDP project/project DIRECTORY=<directory_name> LOGFILE=project_staging_log.log dumpfile=<DMP_FILE>
