WebSphere Extended Deployment and IBM Enterprise Workload Manager

You can enable WebSphere Extended Deployment to work with other autonomic managers, such as IBM Enterprise Workload Manager.

If you enable the on demand router (ODR) to report request metrics, Application Response Measurement (ARM) -enabled autonomic managers like Enterprise Workload Manager can influence how requests are processed in WebSphere Extended Deployment. Enterprise Workload Manager has knowledge and control outside of the WebSphere Extended Deployment domain. Enterprise Workload Manager can use the request metrics to determine if service class policies and transaction class policies that are defined in the Enterprise Workload Manager configuration are met. If you need to make changes to meet the requirements, Enterprise Workload Manager uses its knowledge and control outside of WebSphere Extended Deployment to assist WebSphere Extended Deployment in meeting the broader response time goals for Enterprise Workload Manager.

Support of ARM instrumentation in the ODR enables the reporting of response time metrics on a per transaction basis. ARM is an industry standard for accurate measurements of request and response transactions as they move through various tiers of applications. For more information about ARM and request metrics, see the WebSphere Application Server Information Center.

Any tiers that send requests to WebSphere Extended Deployment must be ARM-enabled to facilitate the interaction between Enterprise Workload Manager and WebSphere Extended Deployment. Any tiers that receive requests from WebSphere Extended Deployment do not need to have ARM enabled, however, enabling ARM on these tiers is encouraged. For example, enable ARM on all application servers in software that works in cooperation with WebSphere Extended Deployment, such as IBM DB2 and so on. Enterprise Workload Manager can make resource level measurements for tiers that do not have ARM enabled. You can also enable ARM reporting on any Web servers that forward requests to the ODR.

For more information about the IBM Enterprise Workload Manager, see the BM Enterprise Workload Manager Information Center.
