1.2 Understanding the Oracle CEP Visualizer User Interface

As Figure 1–1 shows, the Oracle CEP Visualizer has the following main panes: ■ Section 1.2.1, Top Pane ■ Section 1.2.2, Left Pane ■ Section 1.2.3, Right Pane Figure 1–1 Sample Oracle CEP Visualizer Window Figure 1–1 shows a domain that contains a single server instance called NonClusteredServer . The server contains four deployed applications: com.bea.wlevs.dataservices , cql, fx, and signalgeneration; the signalgeneration application is currently opened. The right pane contains the configuration of the rules of the processor1 stage; in particular, processor1 has been configured with rules vTrend, trend, percent, and S. The application called com.bea.wlevs.dataservices is associated with Oracle CEP Visualizer itself and is always deployed in an Oracle CEP server instance. Section 1.3.1.1, The com.bea.wlevs.dataservices Application for details. Overview of Oracle CEP Visualizer 1-3

1.2.1 Top Pane

This pane includes the most used buttons: ■ Home button that takes you to the main Oracle CEP Visualizer page. ■ Security button that takes you to the security page in which you can add or configure users and groups and map users to application roles and task roles; see Chapter 20, Overview of Security Tasks for details. ■ Dashboard button takes you to the performance management screen that you use to monitor the throughput and latency of a running application and its stages; see Section 1.2.4, Overview of the Oracle CEP Visualizer Dashboard for more information. ■ ViewStream button takes you to a screen from which you can monitor the messages streaming through the configured HTTP publish-subscribe channels; see Section 1.2.5, Overview of the Stream Visualizer ViewStream Panel for more information. ■ Full Screen button fills your entire computer screen with the Oracle CEP Visualizer tool; press the Esc key to return to a normal screen. ■ Preferences button takes you to a page where you can set user preferences, such as the language and maximum number of open panes, and accessibility settings such as restricting the maximum number of open panes to 1 and disabling Full Screen mode. ■ Help button takes you to the task-oriented online-help hosted by the Oracle CEP server.

1.2.2 Left Pane

This pane displays a domain tree for the domain that includes all the objects contained in the domain, such as the Oracle CEP server instances, the deployed applications and services within each server instance, and domain-level security configuration. The domain name is determined by the Oracle CEP server config.xml file domain element. For example, the domain tree is named mydomain if your config.xml file is like this: domain namemydomainname domain The Open Items box in the lower half of the left pane lists the items that are currently open, making it easy to return to or close the windows after you have navigated away from them. Any open panels that require refresh are marked with a red X in the Open Items list. For more information, see Section 1.2.7, Oracle CEP Visualizer Panels that Require Refresh .

1.2.3 Right Pane

This pane is a multi-document container. When you open multiple documents, the documents are overlaid one on top of the other. This pane displays information about objects that you have clicked on in the left pane. The format of the information depends on the object; for example, if you click on a deployed application in the domain tree in the left pane, the right pane shows general information about the application General tab as well as various visual representations of the event processing network of the application Event Processing
