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.

About this task

When you use a cluster manager, offline nodes can be configured to start up automatically. However, if you must stop cluster members for maintenance or troubleshooting, you must set your cluster manager to manual mode.

Procedure

  1. Set up a WebSphere® Application Server load-balanced cluster.
  2. Install System Automation for Multiplatforms on all nodes.
  3. Configure the WebSphere Application Server Network Deployment cluster with automatic restart.

Example

When you want to set your cluster manager to manual mode, run the following command:

samctrl -M t

When you want to reinstate automatic mode, run the following command:

samctrl -M f
