WebSphere® Application Server can
be configured in a cluster to achieve high availability. You can select
from various cluster configurations, such as a load-balance cluster,
or a cluster with shared disk.
Configuring a WebSphere Application Server Network Deployment load-balanced cluster
You can configure IBM® HTTP Server and WebSphere Application
Server Network Deployment together
to create a load-balanced cluster for improved performance and scalability.
This type of cluster is a common deployment configuration for products
that are based on Tivoli®'s process automation
engine.
Configuring a WebSphere Application Server Network Deployment cluster with automatic restart
You can automate the startup of cluster members to facilitate
the implementation of high availability in your topology. You can
introduce cluster management software, such as IBM Tivoli System
Automation for Multiplatforms,
to detect server status and bring cluster members online when required.
Configuring a WebSphere Application Server Network Deployment cluster with shared disk
You can create a WebSphere Application
Server Network Deployment cluster
that uses a shared disk and a WebSphere Application Server profile
across multiple nodes. The shared disk can be mounted on one active
node where you can start WebSphere Application Server services
and applications. To create a shared disk cluster, you use cluster
management software, such as System
Automation for Multiplatforms.
