What is the Queuing System architecture?
The Queuing System architecture is composed of the following modules:
1.Job Storage: Jobs are stored in the Project and Timesheet Queues. 2.Job Polling: The queues are polled to check for waiting jobs at regular intervals by a Job Polling thread. The PWA administrators can configure the frequency of the polling through the Queue Settings page.
3.Job Processing: If the Job Polling Thread finds new jobs, a Job Processing thread will be spawned for each of the waiting jobs until the maximum number of Job Processing threads is reached.
4.Job Status Check and Management: This is the end-user-facing module of the Project Server queue. This module is comprised of:
Manage Queue User Interface (UI): This feature is used by administrators to view the status of jobs in the queue.
Queue Settings UI: This feature is used by administrators to view or change the settings, such as the polling interval.
My Jobs UI: This feature is available to every PWA user. It is used to display the status of a particular user’s jobs.
Queue Status Project Server Interface (PSI): This feature is used by Project Professional 2007. Developers can also use the PSI to retrieve the status of any queue job.
