procedure builder

[Turtle]

Hello peeps,

I am losing the will to live! below is the connect string for Procedure Builder....

PL/SQL> .CONNECT DB scott/tiger@t:net:base
PDE-POC011 ORA-06401: NETCMN: invalid driver designator
PDE-POC004 General OCI error. An error message with more detailed information is supplied.

why? and where does the error message with more detail live.

I have used sql/plus and connected successfully to prove I can get in.

Thanks for any help.

Paul
