CHAF - an object-oriented framework for configuring applications in a clustered environment

In high availability clustering solutions, an application must be configured properly to run within the framework of the high availability solution. This configuration is often cumbersome, and thus the probability of configuration errors increases. In this paper, we propose a framework, called CHAF, to build configuration tools for high availability clustering solutions. We show how CHAF is scalable to a variety of applications. Finally, we provide implementation snapshots of a feature that has been implemented using CHAF. This feature was successfully released as part of the most recent release of the Solaris Cluster product (Solaris Cluster 3.2).
