Challenges of Managing the Enterprise

 
The IT systems of today are growing more complex with each iteration of new technology. It is not unheard of to have 2,600 instances to manage. These instances can be as close as next door or on the other side of the world. By using Enterprise Manager, you can:

  • Extract the information needed for critical and timely decisions.
  • Manage the extraordinary number of systems in an efficient manner.
  • In conjunction with virus protection software, prevent viruses and worms from attacking your system.
  • Manage your ecosystem, that is, your Oracle platform and all your third-party software, including your storage systems, hosts, routers, and so on.
  • Reduce your hardware and labor costs, that is, manage thousands of systems as if they were one.

Availability of Information

Mission-critical decisions are dependent on accessible and up-to-date information. The reporting mechanisms within Enterprise Manager can answer the following:

  • Why is it taking so long for banking transactions to process from the branch in London to the branch in New York? The answer is available using the Application Performance Management functionality.
  • We are forecasting our budget for next year. Do we foresee needing additional storage devices? If so, what machine needs these devices? Set up the Automatic Storage Management option to help analyze your needs.
  • Host XYZ is always going down. Why? Look at the home page for the host and analyze the information. Maybe the host needs to be reconfigured?

These are just a few of the questions enterprise Manager can help you answer. The up-to-the-minute information on the Grid Control provides clear and concise information.

Not only is this information available from any supported Web browser on any desktop, it is also available using any personal digital assistant (PDA) that supports Microsoft Pocket PC IE. The EM2Go mobile component of Enterprise Manager makes this instant availability of information possible without any additional work on your part.
