Generation AP Automation & Dynamic Discounting Oracle WebCenter Contract Lifecycle Management (CLM) Search ORA-12541: TNS: no listenerYou are here: Home / ora-12451 tns no listener Resources / ORA-12541: TNS: no listener ORA-12541 In Oracle, a listener is a process that runs on the database server computer. It manages the traffic of incoming connect requests from clients to the database server, http://stackoverflow.com/questions/13358656/oracle-client-ora-12541-tnsno-listener 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 file can be found in $ORACLE_HOME/network/admin or ORACLE_BASE\ORACLE_HOME\network\admin on Unix and Windows platforms respectively. When https://www.tekstream.com/resources/ora-12541-tns-no-listener/ 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. To make sure all instances are correct, you can obtain basic information about the listener and the configuration settings by simple commands, such as the STATUS command. The status command will give basic informatio
