Novell Doc: Identity Manager Driver 3.5.1 for JMS

10.1 Default Driver Parameters

The driver import file defines some basic functionality in the driver. How the driver handles this information for each channel is explained in the tables below.

Table 10-1 Driver Settings

Parameter	Sub-Parameter	Description
Default JMS version		Specifies the API version this driver should use when communicating with message brokers. If you are uncertain, 1.0.2 is the more widely adopted standard. This setting is global for all message brokers.
Broker ID		Specifies an identifier for this broker by which it is known in the Identity Manager namespace.
Show connection-related parameters		Displays connection-related parameters such as JNDI connection factory names and usernames or passwords.
	Username	Specifies the username used to authenticate to the message broker.

	Show queue connection factory options	Specifies the JNDI name of the connection factory used to create connections to queues.
	Show topic connection factory options	Specify the JNDI name of the connection factory used to create connections to topics. Specify the Client ID used to create durable topic subscriptions. NOTE:Changing this value after durable subscriptions have been defined is not recommended. If it is changed, the Publisher is unable to unsubscribe from existing topic subscriptions unless the client ID is set to the same value the subscriptions were created with.

	Default message priority	Specifies the message priority. 0-4 indicates normal delivery 5-9 indicates expedited delivery Specifying expedited delivery can result in “out-of-order” message processing. This setting is global for all sent messages.
	Default message type	Specifies the default message type as text or bytes. This setting is global for all sent messages.
	Show default message properties	Specifies whether to display parameters that show the properties sent with messages. Message properties can be used to prevent message loopback or to pass application-specific information in messages. These properties are global for all sent messages.
	Name	Message property names beginning with “JMS” must match those defined by the JMS specification or third-party providers. Property names fall into three general categories: 1. Standard JMS properties. They usually begin with “JMS” or “JMSX”. 2. Provider-specific properties. They usually begin with “JMS_”. 3. Application-specific. Anything else.
	Value	Message property value.

10.1.1 Showing Additional Destinations

The default configuration includes the ability to show two destinations each for the Publisher and Subscriber channels.

To add more destinations:

In iManager, on the Driver Parameter’s page, click Edit XML.
Look for a < group> element. Within the group, look for an element that begins with <definition display-name="Show destination". . .>
Copy the entire contents of the <group> element and paste it after the other entries for Show destination.
Within the Show destination element, there’s an entry for “name=singorex” or “name=pignorex” (signore is for Subscriber channel destinations; pignore is for Publisher channel destinations). You should look for the highest number and increment the number.
Scroll down through the copied XML and locate the <definition display-name="Destination unique id" gcv-ref="destination_1.unique-id"> element. You also need to increment the destination_ x number to be the same number as the signore, pignore value.
Save your XML.

You can repeat this process as many times as needed to add additional destinations for the Publisher or Subscriber channel.

10.1.2 Considerations When Removing the Driver

If you decide to delete the driver for a Publish/Subscribe configuration that is using a durable subscription, there are several steps you must manually complete to ensure that the subscription is removed.

In iManager, edit the driver object. For every destination, you must delete the Destination Unique ID and Destination JNDI Name.
Restart the driver.
Open the driver object, then click General > Other.
Select the DirXML-DriverStorage attribute, then click Edit.
Confirm that there are no child elements of <subscription/>. If none exist, the durable subscription has been removed from the message system.
