Administer instances of WebSphere Application Server Network Deployment

WebSphere Application Server Network Deployment product includes a default instance that consists of a single deployment manager server, named dmgr. The deployment manager includes the administrative console application. The deployment manager does not host J2EE applications. To serve your J2EE applications, add (or federate) a WebSphere Application Server V5.0 instance into the Network Deployment domain. The deployment manager provides a single point from which to manage and administer the nodes in the Network Deployment domain (or cell), and the applications contained within the nodes. The deployment manager also allows you to create clusters and cluster members, which provide workload management functionality and failover support.

The instance management scripts for WebSphere Application Server Network Deployment are shipped in the /QIBM/ProdData/WebAS5/ND/bin directory. Scripts for adding, removing, synchronizing, starting, and stopping nodes are located in the bin directory of the WebSphere Application Server product root directory, /QIBM/ProdData/WebAs5/Base/bin. These scripts represent actions that are performed on a WebSphere Application Server instance, and so they are shipped with that product.

These topics describe how to work with nodes in WebSphere Application Server Network Deployment.

Add nodes to a Network Deployment instance
Use the addNode script to incorporate an instance of WebSphere Application Server into a Network Deployment cell. An instance that has been added to a cell is called a node.

Remove nodes from a Network Deployment instance
Use the removeNode script to remove a node from a Network Deployment cell.

Synchronize node configuration changes
This topic describes how to use the administrative console and the syncNode script to synchronize node configurations in a Network Deployment cell.

Clean up nodes in a Network Deployment instance
Use the cleanupNode script to remove a node configuration from the cell repository.
