338 Chapter 15 Optimizing ClusterCATS
To enable dynamic addressing:
1 Verify that you can access your server via its maintenance address. If not, assign
one to the server using the procedure described in “Setting up maintenance IP
addresses” on page 335.
2 Configure your Web server to support ClusterCATS dynamic IP addressing.
For Netscape Enterprise Server: Verify that the IP addresses associated with the
primary Web Server and Hardware Virtual Servers are configured on your system
via the Network Control Panel. If these addresses are not configured on the
system, the Netscape Enterprise Server will fail to start. In order for failover to
work properly, the primary Web server can not be bound to a specific IP address.
If it is, remove the binding using the Netscape Administrative Server.
For IIS: Verify that you have a unique IP address (or addresses) assigned to each
Web site on the Web server in the MMC. If IP addresses are not assigned to your
Web server yet, assign them now. Note that with IIS 4.0, you may have to
manually enter the IP address if it does not appear in the drop down list on the
Web Site properties tab.
3 Reboot your server to apply these changes.
4 Create a cluster using the Cluster Setup Wizard.
Note
Do not specify a maintenance address when adding cluster members. Since the
IP addresses for the cluster members are still bound to their NICs, there is no
need to do this. For more information about creating clusters, refer to “Creating
clusters with the Cluster Setup Wizard” on page 252.
5 Verify that your cluster is functioning properly.
