Provides another level of ColdFusion-specific load balancing by actively
monitoring the ColdFusion Server for failures via application probes that you
create to periodically test a ColdFusion URL on your site. If the Probe's
validation test fails, it restricts the Web server on which the site resides and
redirects the restricted server's HTTP traffic to another server in the cluster. This
new feature extends ClusterCATS' automatic monitoring and failover
capability.
Tighter Integration with Cisco LocalDirector
ClusterCATS is now able to provide the availability and load balancing data it
acquires directly to a Cisco LocalDirector so that the LocalDirector can route
inbound HTTP traffic to the most appropriate Web server in your cluster.
Important ease-of-use features
These ClusterCATS features make creating and managing your server clusters easy,
fast, and secure:
Graphical Administration Utilities
The Windows-based Explorer allows you to centrally administer NT or UNIX
clusters easily and quickly. If you run a UNIX-only environment and do not
have a Windows machine (NT, 98, or 95) on which to install the Windows-based
Explorer, you can use the Web-based ClusterCATS Explorer together with
included server utilities to administer your cluster members.
Note
The ClusterCATS Server Administrator lets you perform maintenance and
troubleshooting tasks on each server in your cluster. These tasks include
putting a server into maintenance mode so that you can update software or
content, stopping and starting the ClusterCATS service, and adding and
removing the ClusterCATS filter from the Web server service.
Cluster Administration Security
ClusterCATS provides three administrator security levels that you can configure
for the appropriate level of security within your organization.
Offline Maintenance Support (Windows NT only)
ClusterCATS lets you configure an additional IP address for each Windows
server in your cluster so that you can perform update and server maintenance
tasks without removing the server from the cluster or disconnecting it from the
network
Load balancing features
ClusterCATS provides the following load balancing features:
The Web-based Explorer does not contain all of the configuration
and administration features found in the Windows-based Explorer.
