Chiappa:

Thanks for your warning and I will use it with caution.

But your suggestion did not work for me. The Oracle Connection form has three fields: User Name, Password and Connection String.

If I leave Password and Connection String empty and provide the value you suggested, I get an error message, "ORA-01005: null password given;logon denied."

If I leave the user name and password empty and supply the value in the Connection string, I get an error message, "ORA-01041: internal error.hostdef extension does not exist."

Please advise.
