6 Optimizing Manageability

Complex environments demand coordinated configuration changes, system upgrades, and new application rollouts. The topics in this section describe how to automate and simplify operations in high availability architectures, allowing you to step toward self-managing Oracle databases.

This section contains these topics:

6.1 Intelligent Infrastructure

Oracle Database has a sophisticated self-management infrastructure that allows the database to learn about itself and use this information to adapt to workload variations or to automatically remedy almost any potential problem. The self-management infrastructureFoot 1  includes the following:

6.2 Change Assurance

Oracle Database provides automatic capture and replay of workloads before and after changes so that you can analyze the effect of a database or a SQL change:

6.3 Oracle Enterprise Manager Grid Control

By reducing the amount of human intervention required to execute routine and repetitive tasks, services become more stable, reliable, and available. This is particularly important when administrators must manage very large numbers of systems as efficiently as possible.

Oracle Enterprise Manager Grid Control is an HTML-based interface that provides the administrator with complete monitoring across the entire Oracle technology stack—business applications, application servers, databases, and the E-Business Suite—and non-Oracle components. If a component of fast application notification (FAN) becomes unavailable or experiences performance problems, then Grid Control displays the automatically generated alert so that the administrator can take the appropriate recovery action.

The components of Grid Control include:

Communication between Grid Control, the OMS, and Oracle Management Agents is done through HTTP. Also, you can enable Secure Sockets Layer (SSL) to allow secure communications between tiers in firewall-protected environments. The Management Agent uploads collected monitoring data to the OMS, which in turn loads the data into the Management Repository. Changes in a target state (such as an availability state change) result in an alert being generated to Grid Control.

Using Grid Control, an administrator can:
