Available servers
•
By default, the Instance Manager deploys a copy of the current cfusion application (data sources, settings,
administrator password, and so on).
•
You can optionally use the Create from EAR/WAR option to create a server with a previously archived application.
Cluster Manager page
The Cluster Manager page in ColdFusion Administrator lets you create and manage clusters of Tomcat servers, each
containing the same ColdFusion application.
1
Add a cluster by typing a name in the Cluster Name box, and clicking Add. This creates a cluster and adds it to the
Configured Clusters table.
2
Add servers to the cluster by clicking the Edit icon next to the cluster name in the Configured Clusters table. This
displays the Edit Cluster Page.
Edit Cluster Page
The Edit Cluster page in ColdFusion Administrator lets you define the server instances for a cluster and to customize
cluster settings.
Managing clusters
Manage clusters using the ColdFusion Administrator. If your ColdFusion application uses session replication, sticky
sessions are not typically required.
Note:
When session replication is enabled, Tomcat propagates session-variable information to all servers in the cluster
every time a session variable changes. Consider whether the application's business requirements require session
replication and whether your network incurs the increased traffic before enabling session replication. Consider using
client variables instead of session variables.
The sticky sessions and session replication options require the use of J2EE Sessions by all instances participating in the
cluster. To enable J2EE sessions, go to the Memory Variables page and enable the Use J2EE session variables option.
Do this for each server in the cluster.
1
In the ColdFusion Administrator, click Enterprise Manager > Cluster Manager.
2
Enter a cluster name and then click Add.
3
Click the cluster name and move the servers to the cluster based on the requirement.
4
(If required) Edit the multicast port.
