I am trying to run a backup using enterprise manager console. It tells me to use enterprise manager 10g console for the same. When I click on the hyper link on the enterprise manager console main screen, it tries to open the following URL http://.catusp.local/em. The error on that screen is listed below - do I need to install something else. Any guidence will be helpful. Thanks in advance.

The error on that screen says:
Failed to Connect

Though the site seems valid, the browser was unable to establish a connection.
