Using Dynamic DNS with BCC 1.2
E
One deployment consideration is how the client computers reconnect to services when cluster
resources fail over to a peer cluster in the disaster recovery location. Typically, the disaster recovery
site is a geographically dispersed site in a different network subnet, which forces the cluster
resources to use a different IP address range. In Novell
later, you can configure BCC to act as a dynamic DNS (Domain Name System) client.

E.1.1 Software Requirements

Install and configure your business continuity cluster using the following components:
Novell Business Continuity Clustering 1.2.1 for OES 2 SP2 Linux
Novell Cluster Services
Novell Open Enterprise Server 2 SP2 for Linux
To integrate dynamic DNS in your BCC solution, use the
included in the BCC 1.2.1 ISO image in the

E.1.2 DNS Server

The examples used in this BCC 1.2 or later solution use the ISC BIND 9 DNS server on Linux. It is
not a requirement that you use the ISC BIND DNS server, but your DNS server must meet the
following requirements:
Your DNS server must support the Dynamic DNS standard in RFC 2136.
If you use the ISC BIND DNS server, you should install the
packages on each node in your business continuity cluster.
We recommend that your DNS strategy involve redundant DNS servers that make use of secure
zone transfers. Furthermore, redundant DNS servers should be implemented at each individual
disaster recovery site.
