I am using Oracle 10g Cluster. So, the listener on 1 Oracle machine hasn't been working for a week now. I get an error:

ORA-12541: TNS:no listener

When I want to start listener from oracle user, listener started without services.

lsnrctl status

So, the issue was resolved:

  1. the 1st problem was that on the cluster not a mounted DB disk. I am restarted MSA.
  2. ocr files was differented between 2 machines. I am changed it and restarted machines with DB.
