"The oracleorahome92tnslistener service cannot be started on the local computer. Error 3: The specified path cannot be found"

Start the command in cmd:

Think about what it will do to your computer? This is not the case. Oh, I think of it. I used to use 360 to sort out my computer a few days ago. Maybe
The listening service is broken.

Symptom:
Unable to start the listener, but can be locally logged in SQL * Plus; I can not log in with PL/SQL, prompt "ora-12535: TNS: Operation timeout"

A problem occurs. Do I not need to use a listener for local login?
1. You can directly log on to the local system without the listener. login method:
Single Instance:
SQL> Conn/As sysdba
Multiple instances
A. Set oracle_sid = orcl (the system logs on to the instance specified by oracle_sid by default)
B. SQL> Conn/As sysdba

2. Local login requires the listener login method:
SQL> Conn/@ orcl as sysdba // you only need to use the @ orcl style to listen to the service.

Through the above analysis, you will understand why the listener is not available, but you can log on to the local SQL * Plus, but cannot log on with PL/SQL.
Error message "ora-12535: TNS: Operation timeout"

After careful analysis

Cause of error: 360 clear the ImagePath keyword in the registry. This key value indicates the position of the listener service startup command (tnslsnr. EXE ).

Modification Method: Enter the registry,

HKEY_LOCAL_MACHINE/system/CurrentControlSet/services/oracleorahome92tnslistener to check whether imagepa exists

Th key value. If not, create it. The type is extensible string value. Its value (my machine) is: "D:/Oracle/ora92/bin/tnslsnr. EXE"

Exit and save the registry.
