Configuration management

We learned in previous chapters that Enterprise Manager collects configuration data for monitored targets. Enterprise Manager also keeps a history of configuration changes for the monitored targets. Collected configuration data can also be used to ensure configuration compliance across multiple targets.

Some best practices for configuration management are discussed in the next sections.

Save configuration snapshots

Whenever you make configuration changes to a component, save a snapshot of the collected configuration. Such snapshots will be very useful in keeping track of all the configuration operations performed by you. Ideally, save a snapshot after initial installation and one snapshot after every configuration, patching, or upgrade operation.

For some applications you may need to make configuration changes on multiple components — in such cases, save a configuration snapshot for all of the components and use the description field to relate all such snapshots...
