ClusterCATS dynamic IP addressing (Windows only) 135

12 Reinstall products that are configured as part of IIS, including JRun/ColdFusion and

ClusterCATS. This should include any products you uninstalled in step 3.

When you install ClusterCATS, you must select the "Server Failover" option during

the installation procedure.

Note: Do not create any clusters at this time.

13 Enable the ClusterCATS dynamic IP addressing scheme using the procedure

described in “Enabling ClusterCATS dynamic IP addressing” on page 135.

Enabling ClusterCATS dynamic IP addressing

Before enabling the ClusterCATS dynamic IP addressing, you must have set up a

maintenance IP address for each web server in the cluster, as described in “Setting up

maintenance IP addresses” on page 133, and bound any websites to the appropriate IP

addresses. The maintenance IP address must be different from the IP address associated

with the website.

This section instructs you to create the cluster while the website is still bound to the IP

address. When creating a cluster, you should not specify the maintenance address. When

you test the cluster, you can remove the websites from the IP addresses and restart.

ClusterCATS creates the address dynamically when the server restarts.

To enable dynamic addressing:

1 Verify that you can access your server by its maintenance address. If not, assign one to

the server using the procedure described in “Setting up maintenance IP addresses” on

page 133.

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 by the

Network Control Panel. If the addresses are not configured, the Netscape Enterprise

Server will fail to start. In order for failover to work properly, the primary web server

cannot 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

website on the web server in the MMC. If IP addresses are not assigned to your web

server yet, assign them now. 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 Restart 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. Because

the IP addresses for the cluster members are still bound to their NICs, there is no need to

do this. For more information, see “Creating clusters with the Cluster Setup Wizard” on

page 54.

5 Verify that your cluster is functioning properly.
