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.
