Chapter 8. Configuring
High
Availability for BAM
To reinforce enterprise-level security and maximize
High Availability (HA)
, an
enterprise deployment topology typically requires a multi-tier architecture that is
composed of the Client tier, the Web tier, the Application Server tier, and the Data-
base tier. Each tier is a complete administration unit, which allows separate in-
stallation and configuration without affecting the other tiers.
A typical BAM HA topology is shown in the following diagram. As you can see,
each tier can have its own HA configuration, which ensures that there is no single
point of failure in the entire architecture:
For simplicity, this chapter only covers the HA configuration for Oracle BAM in the
Application Server tier. After the completion of the BAM HA configuration, you are
free to extend your current topology to include a load balancer, or even a Web
Server in the Web tier.
You will learn the following topics in this chapter:
•
Preparing your HA environment
•
Configuring a WebLogic Server domain for BAM HA
•
Configuring server migration
