Setting up and configuring Axis2 clusters in production


This section will describe in detail how Axis clusters are set up and configured in production systems. The Axis cluster configuration is used for configuring a cluster. Understanding of the Axis2 cluster configuration language is very important when it comes to configuring different clustering setups as well as configuring and fine tuning an Axis2 cluster in production. The clustering configuration section in the axis2.xml file has six main parts. They are as follows:

  • Clustering agent

  • Parameters

  • State management

  • Node management

  • Group management

  • Members

Let us take a look at the semantics and usage of each of these configuration sections in detail.

Clustering agent

The clustering agent is responsible for initializing all clustering-related functionality of an Axis2 member or node. Typically, the initialization of a node in a cluster is handled here. It is also responsible for getting a node to join the cluster. In the default Axis2 clustering...
