Creating a BlackBerry Administration Service pool using DNS round robin that includes the BlackBerry Web Desktop Manager

When you install the BlackBerry® Administration Service, BlackBerry® Web Desktop Manager, or both, the setup application installs the BlackBerry Administration Service services automatically. The BlackBerry Administration Service and BlackBerry Web Desktop Manager require the BlackBerry Administration Service services to run.

If you create a BlackBerry Administration Service pool using DNS round robin, you can install the BlackBerry Administration Service and BlackBerry Web Desktop Manager on each computer in the pool or you can install the BlackBerry Administration Service or BlackBerry Web Desktop Manager on some of the computers in the pool. If you install the BlackBerry Administration Service and BlackBerry Web Desktop Manager on each computer in the pool, you can use the pool name that you specified during the installation process in the URLs for the BlackBerry Administration Service and BlackBerry Web Desktop Manager (for example, https://<pool_name>/webconsole/login or https://<pool_name>/webdesktop/login).

If you do not install both components on each computer in the pool and you try to access one of the URLs using the pool name, the web browser might display an HTTP 404 error message. The HTTP 404 error message occurs when the web browser tries to connect to a computer in the pool that you did not install the component on that you are trying to access. For example, you can install the BlackBerry Administration Service on two of the computers in the pool and the BlackBerry Web Desktop Manager on two other computers in the pool.

To make sure that the web browser does not display HTTP 404 error messages, you can choose one of the following options:
  • You can create separate pools within the BlackBerry Administration Service pool for the BlackBerry Administration Service and the BlackBerry Web Desktop Manager. You can provide your organization's administrators and BlackBerry device users with URLs that include the specific pool names.
  • You can provide administrators and users in your organization's environment with URLs that include the FQDNs of the computers that you installed the BlackBerry Administration Service or BlackBerry Web Desktop Manager on (for example, https://<FQDN_of_computer>/webconsole/login or https://<FQDN_of_computer>/webdesktop/login).

Configure the BlackBerry Administration Service instances in the pool to communicate across network subnets

The instances in the BlackBerry® Administration Service pool use multicast UDP to communicate with each other. If the BlackBerry Administration Service instances are in different network subnets and your organization's network configuration does not permit multicast UDP across the network subnets, you must configure the BlackBerry Administration Service instances to use TCP to communicate with each other. For example, if your organization uses a UDP peer-to-peer firewall filter, you must configure the BlackBerry Administration Service instances to communicate across network subnets.
