Re: Problem connecting to db

What happens if you tnsping the database? Looks like your tnsname.ora file or your tns is not set properly.

Post your tnsname.ora file and post the exact command you type in when you got the error message. We might be able to pint-point the source if we see more info.

Hope this helps.
