Upgrade Guide Create the DNS record for a BlackBerry Administration Service instance 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:///webconsole/login or https:///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:///webconsole/login or https:/// webdesktop/login). Create the DNS record for a BlackBerry Administration Service instance To configure multiple BlackBerry® Administration Service instances for high availability using DNS round robin, you must create a DNS record. The DNS record permits the clients of the BlackBerry Administration Service pool to access the instances using a single DNS name. You must create the DNS record in the same domain as the computers that host the BlackBerry Administration Service instances. Before you begin: • You must configure a static IP address for each computer that you want to install a BlackBerry Administration Service instance on. • You must have permission to manage the DNS. • If you configure DNS round robin, you must configure clients to resolve the DNS name into a list of IP addresses and distribute traffic equally across the BlackBerry Administration Service instances in the pool. 1. Log in to the DNS server. 2. In the DNS management console, access the forward lookup zone that you want to add the BlackBerry Administration Service instance to. 3. To create a new host, type the following information: • In the Name field, type the name of the BlackBerry Administration Service pool that you want to use. 35

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).
Create the DNS record for a BlackBerry Administration
Service instance
To configure multiple BlackBerry® Administration Service instances for high availability using DNS round robin, you
must create a DNS record. The DNS record permits the clients of the BlackBerry Administration Service pool to access
the instances using a single DNS name. You must create the DNS record in the same domain as the computers that
host the BlackBerry Administration Service instances.
Before you begin:
•
You must configure a static IP address for each computer that you want to install a BlackBerry Administration
Service instance on.
•
You must have permission to manage the DNS.
•
If you configure DNS round robin, you must configure clients to resolve the DNS name into a list of IP addresses
and distribute traffic equally across the BlackBerry Administration Service instances in the pool.
1.
Log in to the DNS server.
2.
In the DNS management console, access the forward lookup zone that you want to add the BlackBerry
Administration Service instance to.
3.
To create a new host, type the following information:
•
In the
Name
field, type the name of the BlackBerry Administration Service pool that you want to use.
