Integration with IBM Workload Scheduler

The end-to-end scheduling with fault tolerance capabilities is based on the Common Agent Technology and it enables IBM Z Workload Scheduler to be the master of an IBM Workload Scheduler distributed network. You configure this by connecting one or more IBM Workload Scheduler agents or domain managers directly to IBM Z Workload Scheduler.

IBM Z Workload Scheduler receives events from the IBM Workload Scheduler distributed network and updates the current plan (CP) according to these events. Conversely, every time the current plan is updated, an event is sent to the distributed network to update local plans on the distributed agents.

The fault-tolerant agents can independently continue with scheduling when communications with IBM Z Workload Scheduler are interrupted due to network problems. At the same time, the distributed agents are prevented from acting on IBM Z Workload Scheduler jobs because these are viewed as running on the master, that is the only node that is authorized to operate on those jobs.

Standard agents are not fault-tolerant. Their ability to run jobs depends on a working connection with their domain manager. A standard agent that is linked directly to OPCMASTER, must have a working connection with the end-to-end server to be able to run jobs.

A new type of CPU, named fault-tolerant workstation, is added to IBM Z Workload Scheduler to logically define in the database and in the plan the distributed agents that will be running jobs for IBM Z Workload Scheduler.
