How to Uninstall an Application

6-2 Oracle Complex Event Processing Visualizer Users Guide designed to allow business users to efficiently create syntactically correct Oracle CQL views and queries and apply them immediately to a deployed Oracle CEP application. Using the Query Wizard, you can create Oracle CQL views and query. You cannot create Oracle CQL streams and relations. Your deployed Oracle CEP application must provide the streams and relations. For more information, see Oracle Complex Event Processing Developers Guide for Eclipse. Alternatively, you can modify an existing Oracle CQL view or query; see Section 6.1.2, How to Edit a Rule in an Oracle CQL Processor Using the Query Wizard . To create a rule in an Oracle CQL processor using the Query Wizard: 1. In the left pane, navigate to and expand the Applications node of the Oracle CEP instance to which the application is deployed.

2. Select appname, where appname is the name of the application you want to use.

3. Select the Oracle CQL processor you wish to use: a. To use the EPN diagram: – Click the Event Processing Network tab. – Double-click the Oracle CQL processor you wish to use. b. To use the domain tree: – Expand the appname Stages node, where appname is the name of the application you want to use. – Click the Oracle CQL processor you wish to use. – In the right pane, click the General tab The Processor panel is displayed as Figure 6–1 shows. Note: An Oracle CQL query will immediately begin outputting events if its input channels provide input events. If you plan to use a query selector on a channel with an upstream Oracle CQL processor, you may observe unwanted query results on the downstream channel between the time you add the query to the upstream Oracle CQL processor and the time you configure the query selector on the downstream channel. For more information, see Section 4.2.1.3, Channel Properties: Outbound Channel With Query Selector . Managing Oracle CQL Rules 6-3 Figure 6–1 Oracle CQL Processor Panel

4. Click the Query Wizard tab.

The Query Wizard tab appears as Figure 6–2 shows. Figure 6–2 Oracle CQL Query Wizard
