Hi,
I have grid installed in my pc but the problem is LISTENER does not start automatically. I have to start listener manually and then only LISTENER get started. But before starting listener if you check the status first then here is what is shows if you try LSNRCTL STATUS
MY QUESTION IS HOW SHOULD I MAKE THE LISTENER RUN AUTOMATICALLY ?
Please check the necessary required information below : -
*************************************************************************************************************************************************************************************************************

IF YOU CHECK THE STATUS OF THE LISTENER FROM SRVCTL THEN THIS IS WHAT IT SHOWS :-
[grid@netsystemsolution ~]$ srvctl status listener

[grid@netsystemsolution ~]$ srvctl config listener
