title: Oracle 12c RAC : Start / Stop SCAN Listener one by one
body: <p>On 12c, I understand following command can stop single SCAN Listener;
  srvctl stop scan_listener -scannumber 1</p>
  
  <p>May I ask if we can not specify by the node name or netnum like on 11g ?
  Ex.
  srvctl stop scan_listener -i 2 </p>
  
  <p>And sorry for silly question, but how can get to know the right scannumber or netnum of each scan listner?
  Any advice would be appreciated.</p>
