Extend The Timeout Expiration of an Active Task
You can use the updateProgress link in a BlockingTask to extend the expiration time of an active task.
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 task extension
requests, skip this step. Each blocking task creates its own AMQP message, which contains a reference to
the BlockingTask mentioned in Step 1.
2 Retrieve an individual BlockingTask.
See the request portion of “Example: Handling a Blocking Task,” on page 230.
3 Provide a new timeout value, relative to now, for the task.
Create a BlockingTaskUpdateProgressParams element that specifies the number of milliseconds until the
task times out. See “Example: Extend The Timeout Expiration of an Active Task,” on page 232.
4 POST the BlockingTaskUpdateProgressParams to the updateProgress URL from the BlockingTask.
The new timeout value is set to now (the time when the updateProgress request is executed)
plusTimeoutValueInMilliseconds.
Example: Extend The Timeout Expiration of an Active Task
This request resets the expiration time of the BlockingTask shown in “Example: Handling a Blocking Task,”
on page 230 to ten minutes after the request is processed.
Request:
POST https://vcloud.example.com/api/admin/extension/blockingTask/34/action/updateProgress
Content-Type: application/vnd.vmware.admin.blockingTaskUpdateProgressOperationParams+xml
...
<?xml version="1.0" encoding="UTF-8"?>
<BlockingTaskUpdateProgressParams
xmlns="http://www.vmware.com/vcloud/extension/v1.5">
<Message>Giving you ten more minutes...</Message>
<TimeoutValueInMilliseconds>600000</TimeoutValueInMilliseconds>
</BlockingTaskUpdateProgressParams>
The response includes the entire BlockingTask and shows the new value of the timeoutDate attribute. The value
assumes that the request was made at time 2011-05-11T11:50:55. This example omits most of the response.
Response:
200 OK
