Workload balancing

CICSPlex SM workload balancing provides function that allows the most suitable AOR to be selected to host the execution of an enterprise bean, according to predetermined selection criteria specified by a Systems Administrator.
Note: Note that this AOR selection process evaluates all concurrent execution activity, over the regions designated as possible routing targets, and selects the most suitable region in terms of execution workload, and region stability at the point of enquiry. This is not the same as the cyclic selection of an AOR from all those available in a target scope for serially executed beans. Itis the evaluation of all active transactions within the WLM scope at the time when a new transaction (enterprise bean) is about to be executed, and the selection of the least loaded, or most stable, region to host the object execution.
The implementation of simple workload balancing for all Enterprise Java™ bean throughput has these prerequisites:

When the listed criteria have been met, the implementation of EJB workload balancing is relatively simple. A simple workload specification object (WLMSPEC) needs to be defined specifying the AORs as the target scope. The WLMSPEC object then needs to be installed on all listeners and AORs that are to join the workload. When the WLMSPEC has been installed, all regions encompassed by it will have their EJB workloads balanced after they have been restarted. A detailed example of enterprise bean workload balancing is given in the CICSPlex® System Manager Managing Workloads.
