Options Descriptions
Description By default, the displayed description is the workflow description.
Blocking Determines if the workflow can block subsequent workflows for
the same event topic from receiving an event message while
waiting for a reply.
Subscriptions with blocking enabled receive messages before
subscriptions that are not configured as blocking for the same
event topic, based on priority order. When the workflow is
finished, a message is sent to the next prioritized blocking
subscription. After all blocking subscriptions have processed,
the message is sent to all non-blocking subscriptions
simultaneously.
The blocking option is available only if the event topic is
blockable. This information is provided on the Event Topic tab.
The blocking eligibility is indicated on the Event Topic tab.
n
If you do not select the check box, the event broker does not
block subsequent workflows.
n
If you select check box, the event broker calculates which
workflow subscriptions are eligible for this event based on
the configured conditions and runs the workflows in priority
order. The event broker waits for a response from each
workflow before running the next one. All the changed
parameters from the running of the current workflow are
passed to the next one in the queue.
While waiting for a response, no other workflows are notified
of the event until the consuming system responds.
You cannot modify this option after the workflow subscription is
published.
Working with Provisioning and Life Cycle Workflow
Subscriptions
You create provisioning and life cycle workflow subscriptions so that you can use vRealize Orchestrator to
extend your management of IaaS machines. The provisioning subscriptions extend what you can do
during the provisioning process. The life cycle subscriptions extend what you can do when the user is
managing the provisioned items.
IaaS Service Integration
You create a workflow subscription based on a provisioning or life cycle event topic that runs a custom
vRealize Orchestrator workflow based on a message generated by the IaaS service. vRealize Automation
includes two event topics that you can use for IaaS integration.
n
Machine provisioning. Create workflow subscriptions that run workflows during the provisioning and
disposal of IaaS machines.
