    You're changing the name of the module so that it would be found in the path, that's your problem. You should do a 
    use lib "abc/pm/";
use IDVDb;

    The "use" command should always call the module the same as the module's package statement names it.

      hi
      I tried by giving 
      use lib "abc/pm/";
use IDVDb;

      [download]

      eventhough , it is giving the same error.
      Actual path of "abc/pm/IDVDb.pm" is "/example/abc/pm/IDVDb.pm".
      is there any way to configure @INC variable.

        Well, DUH! use the actual path, then! I used the path you gave in your question and I figured you'd be smart enough to adapt it to the right value yourself.

        Just to make this absolutely clear, if your module is located in /opt/mrn/Foo/Bar/Baz.pm
        and the package line says:
        package Bar::Baz:, then you need to say>
        use lib "/opt/mrn/Foo";

    You probably want something like 
    use lib 'abc/pm';
use IDVDb;

    although you don't say where the directory abc is relative to.

    Look at the perlrun POD which describes the use of the -i argument to add a path to the @INC array. This documentation also includes the environment information that is used by the executable. Setting the PERL5LIB environment variable to include the path of your modules.
