WebSphere Application Server high availability
The WebSphere Application Server high
availability framework eliminates single points of failure and provides peer
to peer failover for applications and processes running within WebSphere Application Server.
The WebSphere Application Server high availability
framework also allows integration of WebSphere Application Server into
an environment that might be using other high availability frameworks, such
as HACMP,
in order to manage non-WebSphere Application Server resources.
Workload sharing
You can configure multiple service integration messaging
engines to distribute workload across multiple application servers.
This allows you to scale out your system to handle larger workloads.
High availability
You can make messaging engines highly available in the
service integration environment.
Service integration high availability and workload sharing configurations
The configuration of messaging engines in service integration
is very flexible. You can have a single messaging engine that does
not provide high availability or workload sharing. With a cluster
bus member, you can have a single highly available messaging engine.
Alternatively, with a cluster bus member, you can have multiple messaging
engines that share workload, or that share workload and also provide
high availability.
