A cross dependency is, from a logical point of view, a dependency
for a local job on a job instance that is scheduled to run on a remote
engine plan.
Use cross dependencies to integrate the workload running on different
engines, which can be HCL Workload Automation for Z engines
(controller) or HCL Workload Automation engines
(master domain manager and backup master domain manager).
The following objects and terms are used to describe and implement
cross dependencies:
Remote engine workstation
A type
of workstation that represents locally a remote HCL Workload Automation engine,
either distributed or z/OS. This type of workstation uses a connection
based on HTTP or HTTPS protocol to allow the local environment to
communicate with the remote environment.
Remote job
A job scheduled to
run on a remote HCL Workload Automation engine.
Shadow job
A job defined locally,
on a remote engine workstation, which is used to map a remote job.
The shadow job definition contains all the information necessary to
correctly match, in the remote engine plan, the remote job instance.
Bind
The
process to associate, in the remote engine plan, a shadow job with
a remote job instance.
From a logical point of view in the local environment:
The remote engine workstation is used to map the remote HCL Workload Automation engine.
The shadow job, defined on that remote engine workstation, is
used to map a remote job instance scheduled to run on that remote HCL Workload Automation engine.
To implement a cross dependency, you must define a normal dependency
for your local job on a shadow job that:
Points to the remote job on which you want to create the cross
dependency.
Is defined locally on the remote engine workstation that points
to the engine where the remote job is scheduled to run.
In the bind process, the shadow job is associated to the remote
job instance.
After the bind is established, the shadow job status is updated
according to the remote job status transition.
When the shadow job status becomes COMPLETE (C) the normal dependency
of the local job is released, and so also the cross dependency of
that local job on the remote job is also released.
