How to Access a Cache With JMX Using Java
13.1.1 Storing Events in the Persistent Event Store
When you record events, Oracle CEP server stores them in a persistent event store. You can use the persistent event store that Oracle CEP server provides or define your own: ■ Section 13.1.1.1, Default Persistent Event Store ■ Section 13.1.1.2, Custom Persistent Event Store ■ Section 13.1.1.3, Persistent Event Store Schema13.1.1.1 Default Persistent Event Store
By default, Oracle CEP uses a Berkeley DB instance bundled with the Oracle CEP server to store recorded events. Berkeley DB is a fast, scalable, transactional database engine with industrial grade reliability and availability. For more information, see: ■ http:www.oracle.comtechnologyproductsberkeley-dbjeindex. html ■ http:www.oracle.comtechnologydocumentationberkeley-dbjei ndex.html By default, Oracle CEP server creates the Berkeley DB instance in: ORACLE_CEP_HOME user_projectsdomainsdomainnameservernamebdb Where ORACLE_CEP_HOME refers to the directory in which you installed Oracle CEP such as oracle_home, domainname refers to the name of your domain, and servername refers to the name of your server For example, oracle_cepuser_ projectsdomainsmydomainmyserver. You can change this default by configuring the bdb-config element db-env-path child element as Section 13.2.1, Configuring an Event Store for Oracle CEP Server describes.13.1.1.2 Custom Persistent Event Store
Optionally, you can create a custom persistent event store provider to store recorded events. For example, you could specify a Relational Database Management System such as Oracle Database or Derby as your persistent event store. For more information, see Section 13.3, Creating a Custom Event Store Provider.13.1.1.3 Persistent Event Store Schema
You do not create the actual database schema used to store the recorded events. Oracle CEP server automatically does this for you after you deploy an application that uses the record and playback feature and recording begins. For more information, see Section 13.2.5, Description of the Berkeley Database Schema . Configuring Event Record and Playback 13-313.1.2 Recording Events
You can configure recording for any component in the event processing network EPN that produces events: processors, adapters, streams, and event beans. Processors and streams always produce events; adapters and event beans must implement the EventSource interface. Additionally, you can configure that events from different components in the EPN be stored in different persistent stores, or that all events go to the same store. Note that only events that are outputted by the component are recorded. You enable the recording of events for a component by updating its configuration file and adding the record-parameters element. Using the child elements of record-parameters, you specify the event store to which the events are recorded, an initial time period when recording should take place, the list of event types you want to store, and so on. After you deploy the application and events start flowing through the network, recording begins either automatically because you configured it to start at a certain time or because you dynamically start it using administration tools. For each component you have configured for recording, Oracle CEP stores the events that flow out of it to the appropriate store along with a timestamp of the time it was recorded.13.1.3 Playing Back Events
You can configure playback for any component in the event processing network EPN: processors, adapters, streams, and event beans. Typically the playback component is a node later in the network than the node that recorded the events. You enable the playback of events for a component by updating its configuration file and adding the playback-parameters element. Using the child elements of playback-parameters, you specify the event store from which the events are played back, the list event types you want to play back by default all are played back, the time range of the recorded events you want to play back, and so on. By default, Oracle CEP plays back the events in a time accurate manner; however, you can also configure that the events get played back either faster or slower than they originally flowed out of the component from which they were recorded. After you deploy the application and events start flowing through the network, you must start the playback by using the administration tools Oracle CEP Visualizer or wlevs.Admin. Oracle CEP reads the events from the appropriate persistent store and inserts them into the appropriate place in the EPN. It is important to note that when a component gets a playback event, it looks exactly like the original event. Additionally, a component later in the network has been configured to record events, then Oracle CEP records the playback events as well as the real events. For more information, see: ■ Recording and Playing Back Events Flowing Through an EPN in the Oracle Complex Event Processing Visualizer Users Guide ■ Commands for Controlling Event Record and Playback in the Oracle Complex Event Processing Administrators Guide13.1.4 Querying Stored Events
You can use the event store API to query a store for past events given a record time range and the component from which the events were recorded. The actual query you use depends on the event repository provider; for example, you would use Oracle 13-4 Oracle Complex Event Processing Developers Guide CQL or EPL for the default persistent event store provider included with Oracle CEP. You can also use these APIs to delete old events from the event store.13.1.5 Record and Playback Example
The sample code in this section is taken from the event record and playback example, located in the ORACLE_CEP_HOME\ocep_ 11.1\samples\source\applications\recplay directory, where ORACLE_CEP_ HOME refers to the main Oracle CEP installation directory, such as d:\oracle_cep. For details about running and building the example, see Event Record and Playback Example in the Oracle Complex Event Processing Getting Started.13.2 Configuring Event Record and Playback in Your Application
Depending on how you are going to use the event repository, there are different tasks that you must perform, as described in the following procedure that in turn point to sections with additional details. To configure record and playback of events in your application: 1. Optionally configure the Berkeley database event store for your Oracle CEP server instance. You may use the default Berkeley database configuration as is. You only need to make configuration changes to customize the location of the Berkeley database instance or to tune performance. See Section 13.2.1, Configuring an Event Store for Oracle CEP Server.2. Configure a component in your EPN to record events by updating the
components configuration file. The component can be a processor, adapter, channel, or event bean. Only events flowing out of the component are recorded. See Section 13.2.2, Configuring a Component to Record Events.3. Configure a component in your EPN to playback events by updating the
components configuration file. The component can be a processor, adapter, channel, or event bean. Only components that are also event sinks can playback events; events are played to the input side of the component. See Section 13.2.3, Configuring a Component to Playback Events.4. Redeploy your application for the changes to take effect.
5. If you have not specified an explicit start and end time for recording events, you
must use Oracle CEP Visualizer or wlevs.Admin to start recording. You must always use these administration tools to start and end the playback of events. See Section 13.2.4, Starting and Stopping the Record and Playback of Events. Note: It is assumed in this section that you have already created an Oracle CEP application along with its component configuration files and that you want to update the application so that components record or playback events. If you have not, refer to Chapter 1, Overview of Creating Oracle CEP Applications, for details.Parts
