Therefore, if application A stores session data for a user, and application A is running on server A, but not server B, session data will replicate to server B, even though there is no use for it there. If your application creates session data for a user, and you have a heterogeneous cluster, the session data will still be replicated across the other nodes.Ī heterogeneous configuration is one that does not have all of the same applications on every node. The default session replication mode is “All to All,” meaning any session data created on a server will be duplicated to all other servers in the cluster.

This tells Tomcat that this application is designed to run on multiple nodes in this cluster.

APACHE TOMCAT CODE

To achieve this we add the following code to the web.xml: The idea behind propagation is: an application is placed on one node in the cluster, it is migrated (copied) automatically to other nodes in the cluster. With your cluster running, placing a normal application on one server will not trigger propagation to other servers.

Before we create the next instance we should install the application we want to test on this cluster. You have created a clustered instance, but you only have one instance, so it is not a very big cluster. To turn on clustering in your Tomcat 8 server all you have to do is add one line of code to your server.xml. However, if you wish to leverage clustering in your enterprise environment the default configuration is not going to be the best route for you. Server.xml 1 Ĭlustering is very simple to setup in Tomcat 8.

And replace the corresponding server.xml file with the. Just start with two instances of Tomcat 8. Settings for the connectors in your server configuration files can be found at the Apache Tomcat 8 website.īelow are two server configurations that you can use to run a simple cluster.

The configuration of these Tomcat instances is well outside the scope of this document, although it is not difficult to accomplish. You can run multiple Tomcat instances on a single virtual/physical machine by tweaking just a few settings, mainly port numbers so the instances don’t interfere with each other. To limit the liability of your attempt at creating a cluster, you can set up a machine, virtual or physical, just for this task. Here's a brief tutorial for Apache Tomcat 8 clustering.
