The following actions are allowed:
resume
Unblock the task and allow it to continue.
abort
End the task, cleaning up any transient objects that it created. Task status is set
to ABORTED.
fail
End the task, setting the status of any transient objects that it created to ERROR.
Task status is set to ERROR.
updateProgress
Reset the timeout value and timeout action for an active task. Use this action
to keep the task alive when it might become subject to a timeout action.
Prerequisites
Verify that you are logged in as a system administrator.
Procedure
1 Retrieve the list of active blocking tasks.
See “Monitor Blocking Tasks,” on page 228. If you are using an AMQP client to handle blocking tasks,
skip this step. Each blocking task creates its own AMQP message, which contains a reference to the
BlockingTask.
2 Retrieve an individual BlockingTask.
See the request portion of “Example: Handling a Blocking Task,” on page 230.
3 Make a request.

Example: Handling a Blocking Task
