Oracle Enterprise Manager effectively keeps your Oracle VM available and running efficiently. Specifically, it provides a graphical user interface for managing Oracle VM Server, guest virtual machines, and server pools. As with Oracle VM monitoring, administration of Oracle VM begins with the Virtualization Central page. You can perform administration tasks such as the following: Create, remove, and manage virtual server pools Register, deregister, edit, reboot, and stop virtual server Start, stop, suspend, resume, pause, un-pause, and edit guest virtual machines Note:

* A Server Pool is a logical grouping of one or more virtual servers that share common storage. A virtual server can belong to only one virtual server pool at a time. Guest virtual machines and resources are also associated with server pools. Oracle VM Server Pool is an aggregate target type in Enterprise Manager to represent the server pool of Oracle VM Servers.

A: Examples of information collected at regular intervals include:

/ Oracle WebLogic Server software installations, including applied patches / Oracle WebLogic Server configuration parameters (e.g. ports, JVM information, JDBC and JMS resources, startup and shutdown classes) and configuration files /

Operating system patches, kernel parameter settings, and installed packages / Hardware components including CPU, memory, storage, and network devices

B: Many performance degradation issues in production application environments occur due to unauthorized configuration change. Organizations using Oracle WebLogic Server and other Application Servers routinely struggle with managing

configurations and enforcing compliance standards across all of their server deployment. Oracle Enterprise Manager provides comprehensive configuration management capabilities that help customers maximize value of their IT assets,

increase the quality of IT services, reduce the cost of managing IT, and meet IT compliance requirements.

D: Ensuring compliance with standards such as SOX (Sarbanes-Oxley), ITIL, and PCI, as well as with unique business standards, is a challenge. Oracle Enterprise Manager ships with several predefined policies for Oracle WebLogic Server

and also enables users to define their own specific policies and groups to quickly demonstrate compliance with various regulations and standards.
