Hello,
Probably that you already have the listener up and running from your installation of SES.
Also, you could check in your Windows Services (from the Control Panel), you'll see that
there is a service like OraclesesTNSListener up and running.
If it is the case, then it's probably why it is telling you the message below when trying to start it again:
TNS-01106: Listener using listener name LISTENER has already been started
Then, before trying to start the listener, you can check if it is already up by running the command : lsnrctl status
If you need to shut it down, then you can run the command : lsnrctl stop
for example, from the command line:
> set ORACLE_SID=ASUSES
> set ORACLE_BASE=D:\ses\
> set ORACLE_HOME=D:\ses\seshome
> cd %ORACLE_HOME%/bin
> lsnrctl status            <== this will give you the status of your listener
> lsnrctl stop              <== this will stop your listener
> lsnrctl start             <== this will start your listener
Hope this can help you and others.

i have done that. i copied the tnsnames.ora, sqlnet.ora, listener.ora files from the c:>oracle-home\network\admin folder into oracle_devhome\network\admin folder. i have also set the environment variable oracle_sid=skoolman. skoolman is my sid as you can see on the tnsnames.ora. but the error massage still comes up as soon as i run forms from the forms builder environment.
but as i said i am able to connect to the database with my user name and pass word from within the forms builder environment to access my tables and create data blocks etc but as soon as i run the form through internet explorer the forms servlet boots up and the error massage ora-12560 tns protocol adapter error pops up.
thanks guys for your heip. please i need more solutions
