Queues

The Queues page is accessed from Job Queue | Queues, and is the main display for job queues defined in your environment.

Queues are groups of jobs grouped together to ensure easier and more efficient job management and prioritization.

    How do priorities work?

    Zend Server will execute jobs according to the priority of the queue they are associated with. Within a queue, Zend Server will execute jobs according to the priority associated with a job.
    However, there are two exceptions to this rule:
    - Should Zend Server identify that the amount of jobs being executed exceeds the amount set in the queue's Max Concurrent Jobs setting (see below), the next queue in line is executed.
    - Should Zend Server identify a job pending execution that has exceeded the time set in the queue's Max Job Wait Time setting (see below), this job is scheduled for immediate execution.

  • Max Concurrent Jobs - the maximum amount queue jobs allowed to be executed at the same time.
  • Max Job Wait Time - the maximum amount of time queue jobs can wait before they are executed regardless queue priority.
  • Connection Timeout - the amount of time (in seconds) the Job Queue daemon tries to establish a connection with the back-end server.
  • Job Timeout - the time frame (in seconds) in which a URL-based queue job must be completed in.
  • Job Retry Count - the number of retries for failed HTTP jobs.
  • Job Retry Timeout - the amount of time (in seconds) between retries for failed HTTP jobs.
