Testing The Dynamic Dns Solution - Novell BUSINESS CONTINUITY CLUSTERING 1.2.1 - ADMINISTRATION Administration Manual

2 Open the copy of the script in a text editor, then modify the BCC variables by modifying lines
62 – 66 of the script.
The uppercase string surrounded by the percent character ( % ) is the BCC variable and should
be replaced with the real value (such as %DNS_SERVER_ADDR%).
For example, lines 62–66 of the script could be modified like the following:
my $dns_server_addr
my $host_name
my $host_record_ttl
my $host_ip
my $key_file
Kcluster1.clusters.site1.company.com.+157+60303.private";
Remember to replace the values with the actual values for your environment.
3 Test the solution by invoking the Perl interpreter on the script via the following command
perl -w /tmp/bcc_dyn_dns.pl
This executes the dynamic DNS script and modify your DNS server. You can test the results as
outlined in Section E.2.4, "Testing the DNS Server," on page
E.4 Testing the Dynamic DNS Solution
After you have created the BCC load scripts for each resource in each of the peer clusters, you are
ready to test the overall dynamic DNS solution.
1 Perform a BCC migrate (failover) of the test resource from the primary cluster to a secondary
peer cluster.
The dynamic DNS script runs before the cluster resource is onlined on the secondary cluster. If
everything works correctly, the DNS server should be updated by the time the cluster resource
comes online on the secondary cluster.
2 Test the results of the dynamic DNS update on the secondary cluster by following the step in
Section E.2.4, "Testing the DNS Server," on page
3 Perform a BCC migrate (failback) of the test resource from the secondary peer cluster to the
primary cluster.
The dynamic DNS script runs before the cluster resource is onlined on the primary cluster. If
everything works correctly, the DNS server should be updated by the time the cluster resource
comes online on the primary cluster.
4 Test the results of the dynamic DNS update on the primary cluster by following the step in
Section E.2.4, "Testing the DNS Server," on page
