1.5.3 IBM Tivoli Workload Scheduler in an end-to-end configuration
In an end-to-end environment, E2E scheduling directly connects IBM Tivoli
Workload Scheduler Domain Managers and their underlying agents and domains
to IBM Tivoli Workload Scheduler for z/OS. IBM Tivoli Workload Scheduler for
z/OS is seen by the distributed network as the Master Domain Manager.
IBM Tivoli Workload Scheduler for z/OS also creates the production plan for the
distributed network and sends it to the Domain Managers. The Domain
Managers send a copy of the plan to each of their agents and subordinate
Domain Managers for execution.
The IBM Tivoli Workload Scheduler Domain Managers function as the broker
systems for the distributed network by resolving all dependencies for their
subordinate managers and agents. They send their updates (in the form of
events) to IBM Tivoli Workload Scheduler for z/OS so that it can update the plan
accordingly. IBM Tivoli Workload Scheduler for z/OS handles its own jobs and
notifies the Domain Managers of all the status changes of the IBM Tivoli
Workload Scheduler for z/OS jobs that involve the IBM Tivoli Workload Scheduler
plan. In this configuration, the Domain Managers and all the distributed agents
recognize IBM Tivoli Workload Scheduler for z/OS as the Master Domain

Manager and notify it of all the changes occurring in their own plans. At the same
time, the agents are not permitted to interfere with the IBM Tivoli Workload
Scheduler for z/OS jobs, since they are viewed as running on the master that is
the only node that is in charge of them.
IBM Tivoli Workload Scheduler for z/OS also allows you to access job streams
and add them to the current plan in IBM Tivoli Workload Scheduler for z/OS. In
addition, you can build dependencies among IBM Tivoli Workload Scheduler for
z/OS job streams and IBM Tivoli Workload Scheduler jobs. From IBM Tivoli
Workload Scheduler for z/OS, you can monitor and control the distributed agents.
In the IBM Tivoli Workload Scheduler for z/OS current plan, you can specify jobs
to run on workstations in the IBM Tivoli Workload Scheduler network. IBM Tivoli
Workload Scheduler for z/OS passes the job information to the Symphony file in
the IBM Tivoli Workload Scheduler for z/OS server, which in turn passes the
Symphony file to the IBM Tivoli Workload Scheduler Domain Managers (DMZ) to
distribute and process. In turn, IBM Tivoli Workload Scheduler reports the status
of running and completed jobs back to the current plan for monitoring in the IBM
Tivoli Workload Scheduler for z/OS engine.
