    Client connection disconnects from database when one instance goes down

      Hi all,
      we installed Oracle 11G R2 RAC on 2 windows 2008 r2 enterprise servers.
      When oracle client is connected to database and the same instace goes down, then client connection through a error like:
      SQL> /
      ORA-03113: end-of-file on communication channel

      SQL> /
      ORA-03114: not connected to ORACLE

      Then if we exit and re-connect then it will connect to the other instance successfully.
      I am new to oracle RAC environment and don't know how to solve the issue.Plz suggest how to overcome this problem.
      Thanks in advance.
