Hi,

On your export string that you used to execute the export, how did you define the connectivity to the database

i.e

exp user_name/password

or

exp username/password@remote_db

If it was the fist, then you either have to define the TWO_TASK=remotedb.domain in your environment or you have to resolute that of using the second option.

Before you proceed, try doing a tnsping, and ensure that you can reach that database.

tnsping remote_db.domain

Hope this would help you.

Thanx.
Sam
