Re: impdp Issue

No kidding. Did they suggest do it like...

  "Curious. When creating the database link, instead of a tns ALIAS in the create statement, you can put, in double quotes, the tns entry found in the tnsnames.ora entry. You must include EVERYTHING on the right hand side of the equal sign, and Not the equal sign." ?
