CDD Configuration Procedures : Overview of Cluster Deployment Configuration

Overview of Cluster Deployment Configuration
This chapter explains how to configure deploy-time settings for a BusinessEvents cluster. Configuration is done using the Cluster Deployment Descriptor (CDD) editor. Settings are saved in XML, to the CDD file.
This chapter assumes you have read and understood the object management and other deploy-time configuration topics in TIBCO BusinessEvents Architect’s Guide.
Basic settings for all object management (OM) types relate to the following:
Processing units configured in the CDD editor are used in the Site Topology editor. You map these logical units to the physical resources in the deployment environment (also known as the deployment topology). See Chapter 5, Site Topology Configuration.
Additional settings are used if certain features or add-ons are used only, for example HTTP channel properties and database concepts properties.
Using Agent Class Properties at Different Levels
The scope of a property depends on the property sheet you add it to. Not all properties are valid at all levels. However, properties that include the agent class name, such as Agent.AgentClassName.checkDuplicates, can be used this way. Here is the scope of each level for the AgentClassName properties:
Cluster level  Applies to all AgentClassName agents in the cluster.
Processing unit level  Applies any AgentClassName agent deployed in the specified processing unit.
Agent class level  Again, applies to any AgentClassName agent, in any processing unit.
