Chapter 12 Configuring ColdFusion Clusters

6

Select the Enable session-aware load balancing check box.

7

Click OK to enable session-aware load balancing for the selected cluster.

Configuring ColdFusion probes in Windows

This section describes the following:

•

“Adding ColdFusion probes” on page 280

•

“Removing ColdFusion probes” on page 285

Adding ColdFusion probes

ClusterCATS lets you set up one probe monitor for each server in the cluster. Each
monitor can have multiple probes associated with it. As a result, clusters will
typically have multiple probe monitors (one for each server), and each monitor may
have one or more probes.

The procedure for adding a new monitor and probe is different from adding a probe
to a server that already has a probe monitor. This section describes how to perform
both activities.

Note

The ColdFusion service must be running on your server to add a probe.
