files and everything seems okay. We Said: From the docs: ORA-12541: TNS no listener Cause: Listener for the source repository has not been started. Action: Start the Listener on the machine where the source repository resides. Basically the Forms server could not find the listener. First check the tnsnames.ora file and ensure that it points to the correct server and port. If tns no listener error in oracle 11g the Forms server is on another machine, test the TNS resolve with tnsping from the command prompt. Finally, check the listener. First, ensure that your listener service is running. C:\Documents and Settings\ME>lsnrctl stat This should show the status of the listener and the services it is listening for. 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.

It manages the traffic of no listener incoming connect requests from clients to the database server, and therefore, is very important. Each time a client requests a network session with a server, it is the listener that receives this client request. The listener will check to see that the client information matches the listener information, and thereby grant (or deny) the request. To learn more about listeners, click here. Generally, the listener.ora tns no listener file can be found in $ORACLE_HOME/network/admin or ORACLE_BASE\ORACLE_HOME\network\admin on Unix and Windows platforms respectively. When there is any problem with the listener, the user will likely run into ORA-12541. The Problem The ORA-12541 message reads, “TNS no listener.” This happens if the listener is either down as it attempts to make a connection or if it has not been started or improperly configured. In addition, it may be caused by a connectivity problem with the network. To figure out what may be causing the problem, follow the solution steps outlined below. The Solution First, make sure that the listener is up and running. To do this, go to the Control Panel into Services under NT or listener control program (LSNRCTL). C:\Documents and Settings\ME>lsnrctl stat This should show the current status of the listener. If the listener is currently not running, re-start the listener service by running the “net start” command by filling in “XX” with the version being used: C:\Documents and Settings\ME>net start OracleOraDbXXg_home1TNSListener If the listener is up and running, the problem may lie with the listener not having been associated with the correct instance or protocol.
