Configuring the Persistent Event Store

Managing Multi-Server Domains 18-3 If you deploy an Oracle CEP high availability application, you can view the Oracle CEP high availability topology. For more information, see Section 18.1.3, How to View Oracle CEP High Availability Cluster Topologies . If you are using Oracle Coherence for clustering, you can view Oracle Coherence topology. For more information, see Section 18.2.1, How to View Oracle Coherence Cluster Topologies . To view all cluster topologies: 1. In the left pane, click the Domain node, where Domain refers to the name of your Oracle CEP domain.

2. In the right pane, click the Cluster tab.

3. In the right pane, click the Topology tab.

The Topology tab appears as Figure 18–2 shows. Figure 18–2 Cluster Topology Tab This tab shows all cluster groups regardless of the cluster implementation. Within a cluster group, the primary server is identified by the icon that Figure 18–3 shows. In Figure 18–2 , the primary server is CEPServer1. 18-4 Oracle Complex Event Processing Visualizer Users Guide Figure 18–3 Primary Server For information on the various tools along the top of the topology canvas, see Section 18.3, Managing the Cluster Topology Diagram . 4. To view the properties for a given group, click on the group in the Group List. 5. To view the properties for a given server instance, click on the server instance in the Group List.

6. To view details on a given server instance, click the Group Member tab and select

the server instance as Figure 18–4 shows. Figure 18–4 Group Member Tab

7. Use the Group Member tab to customize the group table:

■ To change the order of columns, click on the column name in the cache chart and drag left or right. ■ To change the sort order of a column, click the triangle to the right of the column name in the cache chart.

18.1.3 How to View Oracle CEP High Availability Cluster Topologies

Using Oracle CEP Visualizer, you can view an Oracle high availability cluster topology. You can also view cluster group properties and server instance properties. For more information, see Understanding High Availability in the Oracle Complex Event Processing Developers Guide for Eclipse.
