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:
• Configure a static IP address for each computer that you want to install a BlackBerry Administration Service instance
on.
• Obtain permission to manage the DNS.
• If you configure DNS round robin, 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, perform the following actions:
1. In the Name field, type the name of the BlackBerry Administration Service pool that you want to use.
2. In the IP Address1 field, type the IP address of the computer that you want to host a BlackBerry Administration
Service
instance on.
3. Select the Create associated pointer (PTR) record check box.
4. Repeat step 3 for each BlackBerry Administration Service instance that you want to install. When you add entries to
the same pool, you must use the same pool name for all
BlackBerry Administration Service instances.
After you finish: To remove a BlackBerry Administration Service instance from a pool, delete the entry for the IP address of
the BlackBerry Administration Service instance from the DNS server.
