Network deployment (clustered)
The Network Deployment consists of multiple WebSphere® Application Servers in a cluster, where the IMS Server is managed as a single domain by the Deployment Manager.

a two node network deployment cluster for high availability

Use a network deployment (cluster) to sustain a high availability environment. The web servers are deployed on the same application-tier host. A load balancer is at the front of the deployment. Alternatively, the web servers and application servers can be deployed on separate hosts. A network deployment scenario is typically used for medium to large-scale deployments.
You might want to add additional application servers to an existing
network deployment scenario for any of the following reasons:
- To build redundancy into your product deployment (high availability).
- To restore an application server that failed.
- To have deployments that support higher volume of requests or support more users.
Implementation overview
The following list is an overview of how to do
a network deployment.
- Check and comply with the requirements.
- Install and configure the required middleware.
- Prepare the database server. If you are using DB2® or Oracle, create the IMS Server database.
- On Host A, install WebSphere Application Server.
- On Host A, install the WebSphere Update Installer.
- On Host A, install the WebSphere Application Server fix packs.
- On Host A, create a deployment manager profile and custom server profile.
- On Host B, install WebSphere Application Server.
- On Host B, install the WebSphere Update Installer.
- On Host B, install the WebSphere Application Server fix packs.
- On Host B, create a custom server profile.
- On Host A and B, install the IBM® HTTP Server.
- Install the IBM HTTP Server fix packs.
- Create a cluster. Add Host A and Host B as cluster members.
- Start the WebSphere Application Server profile.
- Deploy the IMS Server applications in the WebSphere Application Server.
- Verify the IMS Server deployment on the WebSphere Application Server.
- To implement biometric support, install the Native Library Invoker (NLI) resource adapter.
- Configure the IBM HTTP Server.
- Configure the IMS Server.
- Restart the WebSphere Application Server.
- Configure your single sign-on authentication environment. See the IBM Security Access Manager for Enterprise Single Sign-On Configuration Guide.
- If you want to create reports, install IBM Cognos® Business Intelligence or Tivoli® Common Reporting.
