WARNING: No cluster interconnect has been specified. Depending on
          the communication driver configured Oracle cluster traffic
          may be directed to the public interface of this machine.
          Oracle recommends that RAC clustered databases be configured
          with a private interconnect for enhanced security and
          performance.

Sorry.  I have defined a private interconnect as well as a public interface for both servers in my clusterware system.  I have 2 nodes.  Right now, however, it seems to be using the public interface only and may be impacting the system.  I'm just wondering how to proceed and possible solutions to get rid of this message.  I'm not sure what info is necessary otherwise.  Thank you.

Lacking any other info, I suggest going through the "Configuring the Network" steps in the RAC quick guide
