Central Management Console

You will use the Central Management Console (CMC) extensively to manage your BusinessObjects Enterprise system. This tool allows you to perform user management tasks such as setting up authentication and adding users and groups. And it allows you to publish, organize, and set security levels for all of your BusinessObjects Enterprise content. Additionally, the CMC enables you to manage servers and create server groups. Because the CMC is a web-based application, you can perform all of these administrative tasks remotely.
Any user with valid credentials to BusinessObjects Enterprise can log on to the CMC and set his or her preferences. However, users who are not members of the Administrators group cannot perform any of the available management tasks unless they have been granted rights to do so.
