7.2 Managing workloads

Workload management optimizes the distribution of work-processing tasks in the WebSphere Application Server environment. Incoming work requests are distributed to the application servers and other objects that can most effectively process the requests. Workload management also provides failover when servers are not available.

Workload management is most effective when used in systems that contain servers on multiple machines. It also can be used in systems that contain multiple servers on a single, high-capacity machine. In either case, it enables the system to make the most effective use of the available computing resources.

Implementing workload management

The Advanced application server implements workload management by using server groups and clones. Multiple copies, or clones, of an application server can be created from a server group, which acts as a template for creating clones of an application server.

Workload management is automatically enabled for clones of application servers. Administrative servers can also participate in workload management.

Benefits of workload management

Workload management provides the following benefits to WebSphere applications:

  • It balances client workloads, allowing processing tasks to be distributed according to the capacities of the different machines in the system.
  • It provides failover capability by redirecting client requests if one or more servers is unable to process them. This improves the availability of applications and administrative services.
  • It enables systems to be scaled up to serve a higher client load than provided by the basic configuration. With cloning and modeling, additional instances of servers, servlets, and other objects can easily be added to the configuration.
  • It enables servers to be transparently maintained and upgraded while applications remain available for users.
  • It centralizes the administration of servers and other objects.
