Resources such as applications, libraries, message flows, and message flow nodes have properties that you can update in the BAR file before deployment.
An administrator can use configurable properties 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 integration node (for example, a test system) without needing to edit and rebuild the message flows or the resources with which they work, such as message mappings, ESQL code, and Java™ code. Properties that you define are contained in the deployment descriptor, META-INF/broker.xml. The deployment descriptor is parsed when the BAR file is deployed.
Edit the configurable properties by using either the BAR File editor or the mqsiapplybaroverride command. In the BAR File editor, click a resource on the Manage tab to see its properties in the Properties view. For example, if you select an application, you can set the start mode for that application, or you can enable or disable Java isolation. If you select a message flow, you can change properties for policy sets, monitoring, and the security profile. You can also expand a message flow and set properties for the nodes in that flow.
Use the supplied editor and command to ensure that the contents of the BAR file are correct after the changes are applied. You can also edit the XML-format deployment descriptor manually by using an external text editor or shell script. In this case, you must ensure that you do not invalidate the XML content.
