With the Solution Package for Oracle Database, you are able to drill down from a high level alert at a business service or application health level into the supporting Oracle database infrastructure, to determine what is causing the alert and to take corrective action. This service centric approach makes it easy for application support teams and Oracle DBAs to prioritize incidents and based on the impact to the business.

Solution Packages include a data adapter, real-time memory cache, alert rule engine, pre-configured displays, and a data historian for persisting of real-time performance metrics.
