Retrieve or Update Blocking Task Settings
Timeout settings, default actions, and related messages for blocking tasks are properties of a cloud. They apply
to all organizations in the cloud. Only a system administrator can view or modify them.
When a user requests an operation that is configured to create a blocking task, the system creates a reference
to the operation in the cloud's BlockingTaskReferences container. The system also sends a message about the
task to the configured AMQP broker. A system administrator can retrieve the list of
BlockingTaskReferences by making a GET request to the system's blockingTasks link. An AMQP client can
use information in the message to construct a URL that it can use to retrieve the task. See “Example: Notification
Message Format,” on page 220.
If no action is taken on the blocking task within a specified timeout interval, it is subject to a default action.
You can specify the timeout interval and default action for all blocking tasks by modifying the system's
BlockingTaskSettings element. To configure an operation as a blocking task, add the operation name to the
BlockingTaskOperations element contained by BlockingTaskSettings. See “Task Operations,” on page 226.
Prerequisites
n
Verify that you are logged in as a system administrator.
n
Retrieve the SystemSettings element. See “Retrieve or Update System Settings,” on page 165.
Procedure
1 Examine the response to locate the link that you can use to retrieve the system's BlockingTaskSettings
element.
This link has a rel attribute value of down and a type attribute value of
application/vnd.vmware.admin.blockingTaskSettings+xml, as shown here:
<Link href="https://vcloud.example.com/api/admin/extension/settings/blockingTask"
rel="down"
type="application/vnd.vmware.admin.blockingTaskSettings+xml"/>
2 Retrieve the element.
Make a GET request to the href value of the link.
3 (Optional) Modify the element as needed to change the settings it controls.
See the schema reference.
4 (Optional) Update the modified element with the new contents.
PUT the modified element to the href value of its rel="edit" link. See “Example: Update Blocking Task
Settings,” on page 225.
Example: Update Blocking Task Settings
This request modifies the blocking task settings for a cloud to set the time-out period to 24 hours and adds
media upload as an operation that creates a blocking task. See “Task Operations,” on page 226 for a list of
operation names.
