• Deployment Level If the Deployment Settable checkbox is checked at design time in the Global Variable editor, you can override at the deployment level. Overrides set at the deployment level are used in all deployed engines.
• Service Level (Same Scope as DeploymentLevel in TIBCO BusinessEvents) If the Deployment Settable checkbox and the Service Settable checkbox are both checked at design time in the Global Variable editor, you can override at the service level or service instance level. However, overrides set at the service level are used for all engines because all services (all BARs, that is all PU definitions) are merged when deployed using TIBCO Administrator.
• Engine Instance Level If the Deployment Settable checkbox and the Service Settable checkbox are both checked at design time, you can override at the service instance level. Overrides set at the service instance level are used for the specific engine (PU instance) represented by that service instance.
Caution: Overriding a global variable at the service or service instance level breaks the connection with higher level overrides for that global variable By default, global variable overrides done at the application level are propagated to all lower level global variable settings at runtime.This behavior applies to overrides made using the appmanage utility as well as those made using the TIBCO Administrator UI.If global variables are defined in the TIBCO BusinessEvents project using groups, specify the group path using forward slashes. For example, if a variable JMSuri is located under a group called URIs, specify the variable as tibco.clientVar.URIs/JMSuri.Deployment level overrides In the following folderService and service instance level overrides In the TRA file generated by TIBCO Administrator.The procedure for setting and using global variables at design time is explained in Working with Global Variables in TIBCO BusinessEvents Developer’s Guide.
