This error is new in Oracle 11gR2.  That version changes the way that the Oracle listener works and is configured.  I'm not an expert on 11gR2 "SCAN" listeners either yet.  But, this error indicates that you do not have a "SCAN" listener configured the way that this installer expects.

Did you install or configure an 11g listener in this machine before you started this software install?  If yes, you will need to change (or remove?) that listener configuration first.

Yes, that is the standard command to stop an Oracle listener: "lsnrctl stop".  I would not expect that command to either cause or fix the error you saw though.

I don't understand what you mean by this: "is ok for u...".

Yes, that is the correct command to use if you want to stop the Oracle listener.  But, I don't believe that stopping the listener will prevent the error message you received.  I think that error message indicates that the listener is not configured correctly.  SImply stopping or restarting it is not likely to fix the problem.

Did you have an Oracle11gR2 listener configured before you started this install process?   If yes, how did you configure that?
