    EM unable to connect to DB

      Hi All,
      I have following configuration on my laptop -
      OS - Windows 7 64 bit
      Oracle Database - 11G - 64 bit
      Oracle Client - 11G - 32 bit - required for certain applications.

      The issue I am facing is that EM is not able to connect to DB and I cannot access DB from SQL developer.

      The message is as follows - Enterprise Manager is not able to connect to the database instance. The state of the components are listed below.
      Database Instance - Down
      Listener - Down - TNS-12541: TNS:no listener
      Agent Connection to Database - Down

      For the listener, I moved the files from 64 bit ORACLE_HOME to 32 bit client ORACLE_HOME.

      Request your help on this please.

      Note:- I am very new to this all DB installations. Hence request your help in guiding me step by step.
