Re: Dblink in Oracle10g

I should have stated it was my opinion that it seems cleaner to me. I already have DataPump set up on my databases. I believe it would also take care of any 'become user' issues when doing the import rather than having to code 'connect' statements for the private database links. (If there is a better way to do this part, I'd love to see how that is done!!!)
