9.9 Event Inspector Service Management

Using the Event Inspector service, you can: ■ View the events flowing out of any stage in the EPN ■ Inject events into any stage in the EPN You can use the Event Inspector service to test and debug Oracle CQL queries during development. For more information, see: ■ Chapter 15, Managing the Event Inspector Service ■ Chapter 4.4, Tracing and Injecting Events in the EPN ■ Testing Applications With the Event Inspector in the Oracle Complex Event Processing Developers Guide for Eclipse

9.10 Cache Management

A cache is a temporary storage area for events, created exclusively to improve the overall performance of your Oracle CEP application; it is not necessary for the application to function correctly. Oracle CEP applications can optionally publish or consume events to and from a cache to increase the availability of the events and increase the performance of their applications. A caching system refers to a configured instance of a caching implementation. A caching system defines a named set of configured caches as well as the configuration for remote communication if any of the caches are distributed across multiple machines. Oracle CEP supports the following caching systems: Note: Any changes to rules and Oracle high availability adapters are propagated to the other servers in the same group. That is, all rule and and Oracle high availability adapter configurations is automatically synchronized. Other configuration changes are not synchronized. For example, if you change recordplayback or JMS adapter configuration on one server in a multi-server domain, then these changes are not synchronized with the other servers in the same group.
