ora 12541 tns no listener oracle 11g client ORA-12541: TNS: no listener Oracle Tips by John Garmany You Asked: I get the ora-12514 tns no listener ORA-12541 error message when I try to connect through Forms6i and Reports6i Builder. I've started the listener also. I have no problems accessing the database through SQL*Plus.

correct server and port. If the Forms server is on another machine, test the TNS resolve with tnsping from the command prompt. Finally, check the listener.

Remember that when you run SQL*Plus on the database server, it does not need the listener to connect unless you specify the database tnsnames.ora entry.Try to start the listener service using lsnrctl from DOS prompt. set ORACLE_HOME= cd %ORACLE_HOME%/bin lsnrctl start LISTENER If the listener service is not running, re-start the listener service using the Windows task manager or use the DOS command line utility to re-start the Windows service with the "net start" command: C:\Documents and Settings\ME>net start OracleOraDb10g_home1TNSListener You can use the lsnrctl status command to verify that the listener is down, and lsnrctl start to start your listener.
