This chapter explains how to configure deployment settings for a TIBCO 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, especially Chapter 6, Object Management Options and Chapter 7, Distributed Cache OM.
− Processing units configured in the CDD editor are used in the Site Topology editor, for deployment using the TIBCO BusinessEvents Monitoring and Management component. You map these logical units to the physical resources in the deployment environment (also known as the deployment topology). See Site Topology Overview and sections following.Additional settings are used if certain features or add-ons are used only, for example HTTP channel properties and database concepts properties.The scope of a property depends on the property sheet you add it to. Not all properties are valid at all levels. Use your judgment.For example, 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 applies to any AgentClassName agent, used in any processing unitNote that the TRA files should be used only for system-level settings that must be read before the JVM starts. All other properties are set in the CDD.
• CDD properties set at a lower level override CDD properties set at a higher level. Cluster is the highest level, then processing unit, then agent.
Global variable overrides in the CDD file are ignored if you deploy using TIBCO BusinessEvents Monitoring and Management or TIBCO Administrator. Instead, define global variable overrides in those components. They add the overrides to the end of the CDD file.
