ORA-12502: TNS:listener received no CONNECT_DATA ora 12541 tns no listener oracle 11g client from client Cause: No CONNECT_DATA was passed to the listener. Action: Check that the service name resolved from TNSNAMES.ORA has the CONNECT_DATA component of the connect descriptor. ORA-12504: TNS:listener was not given the SID in CONNECT_DATA Cause: http://stackoverflow.com/questions/13358656/oracle-client-ora-12541-tnsno-listener The SID was missing from the CONNECT_DATA. Action: Check that the connect descriptor corresponding to the service name in TNSNAMES.ORA has an SID component in the CONNECT_DATA. ORA-12505: TNS:listener does not currently know of SID given in connect descriptor Cause: The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a SID for an instance (usually a database instance) that either has https://docs.oracle.com/cd/B19306_01/server.102/b14219/net12500.htm not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener. Action: - Wait a moment and try to connect a second time. - Check which instances are currently known by the listener by executing: lsnrctl services

It manages the traffic of 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 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.
