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.
- Log in to the DNS server.
- In the DNS management console, access the forward lookup zone that you want to add the BlackBerry Administration Service instance to.
- To create a new host, type the following information:
- 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.
