Just learn about listener on RAC (grid)

On 11gR2 RAC (Grid Infrastructure), I tests use LISTENER_SCAN* on port 1521 and LISTENER on port 1522. I would like to check what service names are registered in LISTENER. Umm...

[oracle@db01 ~]$ cat /grid/network/admin/listener.ora
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent
LISTENER_SCAN3=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN3)))) # line added by Agent
LISTENER_SCAN2=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN2)))) # line added by Agent
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN2=ON # line added by Agent
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN3=ON # line added by Agent

[oracle@db01 ~]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN2 exists. Port: TCP:1521
SCAN Listener LISTENER_SCAN3 exists. Port: TCP:1521

[oracle@db01 ~]$ srvctl config listener
Name: LISTENER
Network: 1, Owner: oracle
Home: /grid
End points: TCP:1522

[oracle@db01 ~]$ srvctl status listener
Listener LISTENER is enabled
Listener LISTENER is running on node(s): db01,db02

[oracle@db01 ~]$ srvctl status service -d db
Service service1 is running on instance(s) db1,db2

[oracle@db01 ~]$ lsnrctl status

TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adapter error
TNS-00511: No listener
Linux Error: 111: Connection refused

So, that is not the problem. I was on db01, then used ...

[oracle@db01 ~]$ lsnrctl status "(ADDRESS=(PROTOCOL=tcp)(HOST=db01-vip)(PORT=1522))"

The command completed successfully

OK... I learned to use "lsnrctl" different... I used. "Security = ON: Local OS Authentication", so i can use " lsnrctl status "(ADDRESS=(PROTOCOL=tcp)(HOST=db01-vip)(PORT=1522))". Or

[oracle@db01 ~]$ lsnrctl status db01-vip:1522

If I am on db01 but ask other nodes... it'll error: TNS-01189: The listener could not authenticate the user

It's just something, I learned.
