To reduce negative impact on performance, Adobe Experience Manger processes certain long-running and resource-intensive operations asynchronously as background operations. Asynchronous processing involves enqueuing multiple jobs and running them in a serial manner subject to the availability of system resources.
These operations include:
You can view the status of asynchronous jobs from the Background Operations dashboard at Global Navigation > Tools > General > Jobs.
By default, asynchronous jobs run in parallel. If n
is the number of CPU cores, n/2
jobs can run in parallel, by default. To use custom settings for the job queue, modify the Async Operation Default Queue Config and the Async Operation Page Move and Rollout Config from the web console.
For more information, see queue configurations.
Whenever AEM processes an operation asynchronously, you receive a notification in your inbox and via email (if enabled).
To view the status of the asynchronous operations in detail, navigate to the Background Operations page.
In the Experience Manager interface select Global Navigation > Tools > General > Jobs.
In the Background Operations page, review the details of the operations.
To determine the progress of a particular operation, see the value in the Status column. Depending upon the progress, one of the following statuses is displayed:
Active: The operation is being processed
Success: The operation is complete
Fail or Error: The operation could not be processed
Scheduled: The operation is scheduled for processing a later time
To stop an active operation, select it from the list and click Stop from the toolbar.
To view extra details, for example description and logs, select the operation and click Open from the toolbar.
The job details page is displayed.
To delete the operation from the list, select Delete from the toolbar. To download the details in a CSV file, click Download.
You cannot delete a job if its status is either Active or Queued.
There are several options around asynchronous jobs that can be configured. The following examples show how this can be done using the configuration manager on a local development system.
OSGi configurations are considered mutable content and any such configurations must be deployed as a content package for a production environment.
AEM runs a purge job every day at 01:00 to delete completed asynchronous jobs that are more than a day old.
You can modify the schedule for the purge job and the duration for which details of completed jobs are retained before they are deleted. You can also configure the maximum number of completed jobs for which details are retained at any point of time.
