Order of Precedence at Runtime The order of precedence at runtime, from highest priority to lowest, is as follows: 1. Command-line arguments at engine startup. 2. Properties set in property files specified at the command line. 3. Properties in the deployed TRA file. 4. CDD file, processing unit level (for the current PU). a. Properties b. Settings 5. CDD file, agent class level (for agents listed in the current PU settings, prioritized in reverse order of that list): a. Properties b. Settings 6. CDD file, cluster level: a. Properties b. Message encoding c. Settings EAR file properties (such as global variable overrides) • Global variables set in the CDD file are ignored if you deploy using TIBCO Administrator. They are overridden by variables set in TIBCO BusinessEvents Monitoring and Management. • Note that the TRA files should be used only for system-level settings that must be read before the JVM starts. All other properties should be in the CDD.
