PRCN-2066 or PRCN-02066
Tried to check the status of a listener by srvctl status listener, but it failed with PRCN-02066.
[grid@primary01 ~]$ srvctl status listener -l LISTENER_SCAN1
PRCN-2066 : Failed to retrieve cluster listener for LISTENER_SCAN1 because it has the type of Single Client Access Name Listener
PRCN-2066 means that the listener you specify in the command is not the type of local listener. In fact, it's a scan listener. So it cannot be done in srvctl status listener command.
To correctly check the status of a SCAN listener, we should use srvctl status scan_listener command to make it.
[grid@primary01 ~]$ srvctl status scan_listener -i 1
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node primary02
To check what services are registered with a SCAN listener, you should use the proper way to do it.
