Use the WebSphere Administration console to deploy your EAR file to a cluster. Each Nucleus-based application needs to be installed as follows:
If you are deploying your web application to a page-serving cluster, that application should also be deployed to a web server instance.
If you are deploying the application to a cluster that does not serve pages, but that will run the application, do not deploy the application to a web server instance.
The web server should only route application requests to instances on the web serving instances node, but non-web serving instances will also run the application.
To deploy an application:
Using the Administrative Console for the Deployment Manager, install the application.
If your web application includes a resource reference for your data source, in the WebSphere application installation wizard make sure the reference binding and JNDI name match and are consistent with the name configured in the
JTDatasourcecomponent (excluding thejava:/comp/envprefix).Regenerate the web server plug-in. In the WebSphere Administration Console, go to Servers > Web servers. Select the entry corresponding to your web server.
On IHS with remote web server management enabled, click Propagate Plug-In. The plug-in is propagated automatically.
For all other web servers, click Update Plug-In, locate the plug-in on the deployment manager’s file system and transfer it to the web server host; overwrite the existing plug-in.
