WebForms: ORA-12541: No Listener

[ptreves]

Hello,

I have Windows XP Pro and Windows 98 SE Client computers.
I installed Oracle Forms/Reports Services 10g (9.0.4) and then Oracle
9i, 9.2.0.4 (Database) on the same Linux Red Hat Server Enterprise 3
(ES).

I copied my *.fmx files in the ORACLE_HOME/forms90 subfolder. and try
to invoke them like:

http://linux2005:7777/forms90/f90servlet?config=ienative?form=cadastre

When invoking the Webform I get an ORA-12541 No Listener Pop-up.

1) Did I fail to load a certain listener on my server, OC4J maybe ?
2) What is going on ?

Your toughts ...

PT

PS: I invoked: emctl, apachectl and opmnctl. Anything missing ?

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.
