How to Configure Scalability With a Custom Channel EventPartitioner
23.2.2 How to Configure Scalability in a JMS Application With Oracle CEP High Availability
You can use the ActiveActiveGroupBean to partition an incoming JMS event stream in a multi-server domain with Oracle CEP high availability. This procedure uses the example application from Section 21.1.4, How to Configure Precise Recovery With JMS , including the example EPN that Figure 23–3 shows, the corresponding EPN assembly file that Example 23–6 shows, and the corresponding component configuration file that Example 23–7 shows.

Figure 23–4 Oracle CEP ActiveActiveGroupBean With High Availability For more information, see Section 22.2.2.2, Scalability in an Oracle CEP Application Using the ActiveActiveGroupBean With High Availability . To configure scalability in a JMS application with Oracle CEP high availability: 1. Create a multi-server domain. For more information, see Introduction to Multi-Server Domains in the Oracle Complex Event Processing Administrators Guide. In this example, the deployment group is named MyDeploymentGroup. 23-14 Oracle Complex Event Processing Developers Guide 2. Configure the Oracle CEP server configuration file on each Oracle CEP server to add the appropriate ActiveActiveGroupBean notification group to the groups child element of the cluster element. The Oracle CEP server configuration file, config.xml, is located in the DOMAIN_ DIR servernameconfig directory, where DOMAIN_DIR refers to the main domain directory and servername refers to a particular server instance. For example, Table 23–3 shows cluster elements for Oracle CEP servers ocep-server-1, ocep-server-2, ocep-server-3, and ocep-server-4. The deployment group is MyDeploymentGroup and notification groups are defined using default ActiveActiveGroupBean notification group names. Note that ocep-server-1 and ocep-server-2 use the same notification group name ActiveActiveGroupBean_group1 and ocep-server-3 and ocep-server-4 use the same notification group name ActiveActiveGroupBean_group2. Optionally, you can specify your own group naming convention as Section 23.2.3, How to Configure the ActiveActiveGroupBean Group Pattern Match describes. 3. Create an Oracle CEP high availability application. For more information, see Chapter 21, Configuring High Availability . 4. Configure the EPN assembly file to add an ActiveActiveGroupBean element as Example 23–8 shows.

Edit the component configuration file to configure a jms-adapter element for the inbound JMS adapters as Example 23–9 shows: ■ Each in-bound JMS adapter must listen to a different topic. ■ Set session-transacted to true. Example 23–9 jms-adapter Element for Inbound JMS Adapters ?xml version=1.0 encoding=UTF-8? wlevs:config xmlns:wlevs=http:www.bea.comnswlevsconfigapplication xmlns:ha=http:www.oracle.comnscepconfigcluster ... jms-adapter nameJMSInboundAdaptername event-typeStockTickevent-type jndi-provider-urlt3:ppurich-pc:7001jndi-provider-url destination-jndi-name.Topic1destination-jndi-name session-transactedtruesession-transacted ... jms-adapter jms-adapter nameJMSInboundAdapter2name event-typeStockTickevent-type jndi-provider-urlt3:ppurich-pc:7001jndi-provider-url destination-jndi-name.Topic2destination-jndi-name session-transactedtruesession-transacted ... jms-adapter wlevs:config For more information, see Chapter 7, Configuring JMS Adapters . 6. Define a parameterized message-selector in the jms-adapter element for each JMS inbound adapter. Edit the component configuration file to add group-binding child elements to the jms-adapter element for the JMS inbound adapters. Add one group-binding element for each possible JMS message-selector value as Example 23–10 shows. Example 23–10 jms-adapter Selector Definition for ocep-server-1 jms-adapter nameJMSInboundAdaptername event-typeStockTickevent-type jndi-provider-urlt3:ppurich-pc:7001jndi-provider-url destination-jndi-name.Topic1destination-jndi-name session-transactedtruesession-transacted message-selector{CONDITION}message-selector bindings group-binding group-id=ActiveActiveGroupBean_group1 param id=CONDITIONacctid = 1000param group-binding group-binding group-id=ActiveActiveGroupBean_group2 param id=CONDITIONacctid 1000param group-binding bindings jms-adapterParts
