If you do not have permission to create the directory object (and assuming that the directory object does not already exist),
you‘ll need to send a request to your DBA (or someone else that has the appropriate privileges) in order to create a directory for you and to grant you access to that directory.
have only user privileges, so i cant use commands like create directory
