Re: WebForms: ORA-12541: No Listener
Date: Sun, 19 Sep 2004 05:41:11 GMT
From the Oracle documentation at http://docs.oracle.com
TNS-12541 TNS:no listener
Cause: The connection request could not be completed because the listener is not running.
Action: Ensure that the supplied destination address matches one of the addresses used by the listener. Compare the TNSNAMES.ORA entry with the appropriate LISTENER.ORA file (or TNSNAV.ORA if the connection is to go by way of an Interchange). Start the listener on the remote machine.
You need to spend some time in the database Concepts manual. In summary - communication between a client and the database is initiated through a 'database listener' on the database server. In this case, the client is the web form around the Apache listener..
The listener is generally started using the WIndows TNSListener service or the *nix 'lsnrctl' executable. Received on Sun Sep 19 2004 - 07:41:11 CEST
