IBM MQ messaging provider connection factory broker properties
Use this panel to view or change the broker settings of the selected connection factory, or topic connection factory, for use with the IBM MQ messaging provider. These broker settings determine how the IBM MQ messaging provider interacts with a broker for the purposes of publishing messages and subscribing to topics. Updates to the settings take effect when the server is restarted.
- In the navigation pane, click to display existing connection factories, or click to display existing topic connection factories.
- If appropriate, in the content pane, change the Scope setting to the level at which the connection factories are defined. This restricts the set of connection factories displayed.
- Select the name of the connection factory, or topic connection factory, that you want to work with.
- In the content pane, under Additional Properties, click Broker properties to display the broker properties of the IBM MQ connection factory, or topic connection factory.
