System objects that are defined in message flows can have configurable properties that you can update within the broker archive (bar) file before deployment. Configurable properties allow an administrator to update target-dependent properties, such as queue names, queue manager names, and database connections.
By changing configurable properties, you can customize a bar file for a new domain, for example a test system, without needing to edit and rebuild the message flows, message mappings, or ESQL transformation programs. Any properties that you define are contained within the deployment descriptor, META-INF/broker.xml. The deployment descriptor is parsed when the bar file is deployed.
Edit the configurable properties using either the Broker Archive editor or the mqsiapplybaroverride command from a command prompt.
Although the two methods indicated above are preferable, you can also edit the XML-format deployment descriptor manually using an external text editor or shell script.
