When the Oracle Listener service does not start, the following measures can be taken to resolve:

A, connect the host string, prompt no listener

Svrmgr> connect INTERNAL/ORACLE@ORCL;
Ora-12541:tns:no listener
svrmgr>

second, run the listener , the protocol-specific component of the prompt address specified incorrectly
Type Lsnrctl in the Start menu run

third, starting the service in Control Panel , the following error occurred
