interface. This allows System and Database Administrators to mitigate system vulnerabilities by defining and implementing configuration policies based on operation best practices, governance and industry standard requirements. The following step by step example will walk you through creating a User Defined Metric and User Defined Policy with Oracle Enterprise Manager. In this case the User Defined Metric will be utilized by the Policy. Step 1, User Defined Metric In the following Step by step example, we will create a User Defined Metric to be utilized by a User Defined Policy in the next step. A user defined metric is only needed when the necessary information/metric is not already collected by Oracle Enterprise Manager. To understand the Oracle Enterprise Manager collected information/metrics please view the Oracle Enterprise Manager Extensibility Guide, section on Management Repository Views.
