Admin API fail :: NetConnection.Admin.CommandFailed

I want recieve infomation for recorded stream in FMS Server.

so, i tried use Admin api(getRecordedStreams or getNetStreams).

but, returned below code : NetConnection.Admin.CommandFailed .

What is wrong?

Below  my code :

import flash.net.NetConnection;

import flash.net.NetStream;

import flash.events.*;

var nc:NetConnection;

var resp:Responder;

function onCallSuccess(resObj):void {

  for (var i in resObj) {

     trace("NetStream Top Level data:"+i);

     trace("NetStream Top Level value:"+resObj);

     if (i.toString() == "data") {

        for (var j in resObj) {

           trace("NetStream Low Level Data:"+j);

           trace("NetStream Low Level Value:"+resObj);

        }

     }

  }

}

function script_ncStatus(event:NetStatusEvent):void {

   var info:Object = event.info;

    if (info.code == "NetConnection.Connect.Success") {

      nc.call("getRecordedStreams",resp,"clia/_definst_");  // clia is Application name

    }

}

nc = new NetConnection();

resp= new Responder(onCallSuccess,null);

nc.addEventListener(NetStatusEvent.NET_STATUS, script_ncStatus);

nc.connect("rtmp://localhost:1111/admin","clia","0903");  //admin name : clia, admin password : 0903
