532 Getting Started with Tivoli Dynamic Workload Broker Version 1.1
Sends a job launch request to the Tivoli Workload Scheduler agent, which
in turn transfers the job launch request to the Tivoli Dynamic Workload
Broker server.
The Tivoli Dynamic Workload Broker server:
Retrieves the JSDL definition corresponding to Job3.
Allocates resources to Job3, including a target computer. (Logical and
physical resource requirements for Job3 as well as current resource usage
data are used to find a best-fit resource.)
Submits a job request to its agent on the selected AIX machine.
Waits for the execution result and when it arrives forwards it to the Tivoli
Workload Scheduler agent, which in turn forwards it to domain manager
DMA.
򐂰 Job4 is a job defined to run on workstation TDWB, including an affinity
definition specifying that Job4 must run on the same resource as Job3 did. A
job launch request is sent by domain manager DMA to the Tivoli Workload
Scheduler agent, which in turn transfers the job launch request to the Tivoli
Dynamic Workload Broker server.
The Tivoli Dynamic Workload Broker server:
Retrieves the JSDL definition corresponding to Job4 and submits it to the
agent on the same AIX machine that executed Job3
Waits for execution result and when it arrives forwards it to the Tivoli
Workload Scheduler agent, which in turn forwards it to domain manager
DMA
򐂰 Job5 is a job defined to run on workstation TDWB. A job launch request is
sent by Tivoli Workload Scheduler domain manager DMA to the Tivoli
Workload Scheduler agent, which in turn transfers the job launch request to
the Tivoli Dynamic Workload Broker server.
Since Job5 is not defined with any affinity, the Tivoli Dynamic Workload
Broker server performs the same actions as described for Job3. But this time
another AIX machine is selected as optimal for execution.
11.2.4 Examples of integration architectures
Tivoli Dynamic Workload Broker and Tivoli Workload Scheduler for z/OS
end-to-end can be integrated in several ways. We provide you with some typical
examples along with key characteristics. The purpose is to aid you in choosing
an architecture that fits into your environment and meets your needs and
requirements.

Figure 11-6 shows an integration where:
򐂰 The Tivoli Dynamic Workload Broker server is running on a distributed
Windows 2003 server with its Tivoli Workload Scheduler agent connected
directly to the Tivoli Workload Scheduler for z/OS V8.3 server.
򐂰 The existing distributed network, DomainA, is separated from the workload
broker environment.

Distributed Tivoli Dynamic Workload Broker connected to interpositioned
Tivoli Workload Scheduler domain manager
Figure 11-7 shows an integration where:
򐂰 The Tivoli Dynamic Workload Broker server is running on a distributed AIX
server with its Tivoli Workload Scheduler agent connected to interpositioned
Tivoli Workload Scheduler domain manager DMA.
򐂰 This is a type of architecture that must be used if Tivoli Workload Scheduler
for z/OS end-to-end is Version 8.2 or earlier.
򐂰 Job scheduling on computers managed by the Tivoli Dynamic Workload
Broker requires domain manager DMA to be up and running. Domain DMA
and the broker network are used for the same business area with the same
availability requirements.
