Preparing the MDS Connection Service for Unwired Server Push Notifications

Configure multiple options for the MDS Connection Service from the BlackBerry Administration Service.

1. Open the BlackBerry Administration Service, then from the Servers and components menu, click BlackBerry Solution topology > BlackBerry Domain > Component view > BlackBerry MDS Connection Service.
2. Choose the service instance and click Edit.
3. Configure any of the following:

   Service property	Description	Configuration details
   Device ports	When a BlackBerry application receives an application-reliable push request, it sends a delivery confirmation message to the MDS Connection Service. This message is then forwarded to Unwired Server.	Contact your application developers for the unique port numbers used in the BlackBerry applications that support application-reliable push requests. In Device ports enabled for reliable pushes, type the device port. Use Add to add multiple ports.
   Storing push requests in the BlackBerry Configuration Database.	To manage memory and system resources in your organization's environment, configure the MDS Connection Service to store Unwired Server, Push Access Protocol (PAP), and other Research In Motion® push connections in the Configuration Database. You can also configure storage settings for the Configuration Database. For more information about types of push requests, visit http://www.blackberry.com/developers and review the contents of BlackBerry Java Development Environment Development Guide.	For Push access protocol, in Maximum number of push messages stored, type a number that reflects the total number of push notifications you want the Configuration Database to store.
   Configuring the maximum number of active push connections	You can configure the maximum number of push connections that the MDS Connection Service can process at the same time. If active connections exceed this value, the MDS Connection Service queues these push connections.	For Push access protocol, in Maximum number of active connections, type a number that reflects the number of push notifications required.
   Configuring the maximum number of queued push connections	The MDS Connection Service queues push requests when the number of connections exceeds a limit that you specify for active connections. When the number of queued requests exceeds this limit, the MDS Connection Service sends a "service unavailable" message to BlackBerry devices.	For Push access protocol, in Maximum number of queued connections, type a number that reflects the number of push notifications required.

4. Save all changes and restart the service instance.
