I am unable to set up a listener for Oracle. I am quite new to this stuff. I have created an MFC application that accesses various databases like Access, MySQL etc. When I add a new class and provide a new ODBC datasource (an Oracle DSN) I get the following error: "Driver's SQLSetConnectAttr failed". Please have a look at the file attached. When I test the service using Net8, I get the error "ORA-12541: TNS:no listener". How do I set listeners?
This will provide you with information on what databases this listener is listening for (if you have MTS, you will see listings for DISPATCHERS).
If you don't know about MTS then you probably don't use it.
Also, if you type help at the listener prompt it will give you some of the listener commands which can be usefull.
