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).
Whole Server Migration
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.
