Change applications to support BlackBerry
MDS Connection Service failover
In earlier versions of the BlackBerry Enterprise Server, an organization's push applications connected to only one instance
of the BlackBerry MDS Connection Service central push server. You must make sure that your organization's applications
can access all central push servers.
1. Change the applications to access central push servers only, and not BlackBerry MDS Connection Service instances
that administrators have not configured to also act as central push servers.
2. To change your organization's applications to support central push server failover, perform one of the following
actions:
• Configure an HTTP or HTTPS proxy server that applications send requests through. Use this option if the
applications are located on the Internet. Optionally, you can place the proxy server in the DMZ.
• Configure the application servers to use a list of IP addresses to find an available central push server. If a central
push server does not respond to a request, the application can try to connect to another central push server.
