Part I Introduction to High Availability

Part I contains the following topics:

• Introduction and Roadmap
  Read this section for information on how and why to use this document and high availability environments.
• High Availability Concepts
  High availability involves elements such as load balancing, failover, Real Application Clusters, and profiles (settings).

  When whole server migration occurs, a server instance migrates to a different physical machine upon failure. You must configure whole server migration for Managed Servers if your environment uses special (pinned) services such as JMS and JTA.
