If the listener is not started, start the OracleOraDb11g_home1TNSListener service in the system service;
If the listener is corrupted, use the listener program Configuration in the "Net Configuration Assistant" tool Wizard to configure another listener (you need to delete the original listener ).

4. Pay attention to the login name, password input, and permission selection.
