This IBM Redbooks publication extends the material provided in the Using WebSphere Extended Deployment V6.0 To Build an On Demand Production Environment, SG24-7153 , by providing a z/OS-centric description of the On Demand Router (ODR) and the long-running application support provided with WebSphere Extended Deployment (XD) 6.0.

This book demonstrates the additional value the ODR provides as it is integrated with the existing z/OS Workload Manager. It also describes the long-running application support now available on z/OS with XD 6.0 along with its relationship to the traditional z/OS batch facilities.

This book describes an XD 6.0 installation into our existing ITSO High Availability WebSphere Network Deployment environment as well as step-by-step instructions that take you through the configuration of the ODRs and dynamic clusters. It presents the setting up of a long-running application environment in detail. It uses a sample scenario to demonstrate the integration of an ODR Service Policy with a corresponding WLM Service Policy and the resulting finer grained WLM workload classification that the ODR now makes possible. Additional scenarios take you through the deployment and execution of a long-running workload.
