User Action: Start Oracle CEP Server

1-4 Oracle Complex Event Processing Administrators Guide 1. Stopping the Oracle CEP server. 2. Editing the Oracle CEP server config.xml file located in the servers domain directory 3. Starting the Oracle CEP server. There are some server configuration tasks that you can only perform statically, such as configuring Jetty. There are some server configuration tasks that you can perform dynamically using management beans MBeans. In this case you do not have to manually stop and start the server for the changes to take effect. You can dynamically configure Oracle CEP servers and applications using Oracle CEP Visualizer, wlevs.Admin command line utility, or your own Java code using Oracle CEP standards-based interfaces that are fully compliant with JMX APIs http:java.sun.comjavasetechnologiescoremntr-mgmtjavamana gement . Typically, you statically configure an application when you initially create it, as described in Oracle Complex Event Processing Developers Guide for Eclipse. In particular, you configure the event processing network EPN of the application by creating the EPN assembly file, and configure individual components of the application adapters, channels, and processors by creating their configuration files. After you deploy an application, you can dynamically change its configuration, as well as the configuration of its individual components, by manipulating the MBeans that the Oracle CEP server automatically creates for the application and its components. A typical task is to dynamically configure the Oracle CQL rules for the processors of a deployed application. You do this using Oracle CEP Visualizer, wlevs.Admin command-line utility, or JMX.

1.3.1 Oracle CEP Server Configuration Files

By default, the Configuration Wizard creates domains in the ORACLE_CEP_ HOME user_projectsdomains directory, where ORACLE_CEP_HOME refers to the Oracle CEP installation directory such as d:\oracle_cep. For example, d:\oracle_cep\user_projects\domains\my_domain, where my_ domain is the a domain directory. Each Oracle CEP server you create in this domain will have a subdirectory in my_domain such as c:\oracle_cep\user_ projects\domains\my_domain\server1.
