Workload Management



Search Tips   |   Advanced Search


Workload management optimizes the distribution of client processing tasks by distributing incoming work requests to appservers, enterprise beans, servlets, and other objects. Workload management also provides failover when servers are not available.

In the WAS environment, workload management is implemented using clusters, transports, and replication domains.

Workload management...

  • Balances client workloads, allowing processing tasks to be distributed according to the capacities of the different machines in the system.

  • 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.

  • Enables systems to be scaled up to serve a higher client load than provided by the basic configuration. With clustering, additional instances of servers, servlets, and other objects can easily be added to the configuration.

  • Enables servers to be transparently maintained and upgraded while applications remain available for users.

  • Centralizes the administration of servers and other objects.
