This document is a resource for system administrators and operators responsible for monitoring and managing a WebLogic Server installation. It is relevant to all phases of a software project, from development through test and production phases.
This document is organized as follows:
This chapter, "Introduction and Roadmap," describes the audience and outlines the content for this book.
Overview introduces elasticity and related terminology.
Requirements for Configuring Elasticity lists and describes the requirements for configuring elasticity, including creating a dynamic cluster and provisioning machines.
On-Demand Scaling describes how to manually add or remove running dynamic server instances to scale up or scale down a dynamic cluster based on demand.
Elastic Actions introduces the new elastic actions, the scale up and scale down actions.
Calendar-Based Scaling describes how to perform calendar based scaling by creating a calendar based policy, defining a schedule for the policy, and assigning a scaling action to the policy.
Policy-Based Scaling gives an overview of policy based scaling and outlines an example of performing policy based scaling using smart rules.
Configuring the Data Source Interceptor introduces the data source interceptor and describes how it can be used during scaling operations to determine the limit of total connections that can be created from the domain to the databases so that their capacities are not exceeded.
Configuring the Script Interceptor introduces the script interceptor and describes how it can be used to integrate WebLogic Server with other systems during scale up and scale down operations.
See Overview of the WLDF Architecture in Configuring and Using the Diagnostics Framework for Oracle WebLogic Server for a description of the WebLogic Diagnostics Framework (WLDF), a monitoring and diagnostic framework that defines and implements a set of services that run within WebLogic Server processes and participate in the standard server life cycle.
Dynamic Clusters in Administering Clusters for Oracle WebLogic Server describes how to create and configure dynamic clusters.
