Thanks,

Sure. Here's an example from my server:

SQL> select * From all_directories where directory_name = 'SLIKE_4001';

OWNER      DIRECTORY_NAME  DIRECTORY_PATH
---------- --------------- ----------------------------------------
SYS        SLIKE_4001      \\my_server\d$\Home\Slike_4001

Do we need to create a mount point for the remote directory location in DB server and give permission to Oracle user? for this to work.

The instance owner (the account that started the Oracle instance service, see services.msc OracleService<SID>) must have network privileges which is not a good idea, for security reasons it should be strictly local.

An oracle directory object is merely a synonym, an abstraction, of a directory that exists on the database server.
Oracle does not know nor care if that directory is on local disks or mounted from a SAN or some other server.

Hi,

Thanks for your reply. It means that we have to create a Network Mapped / mounted drive in the DB server and then Create the Oracle DIRECTORY object pointing to the Mapped drive / Mounted drive. Right?

Thanks,
Ninan.

And give the access rights to the Oracle instance owner which is a security problem in Windows world.
