Scheduled jobs through the UI

📘
Note
This topic is for CMS administrators and developers with administrative access rights.

A scheduled job is a service performing a task (job) at a given time interval. An administrator can start a job manually. By default, Optimizely platform with Optimizely Content Management System (CMS) and Optimizely Commerce Connect includes several scheduled jobs. Some are enabled by default with preset values. You can develop customized, scheduled jobs for specific website tasks.

Administer scheduled jobs

Go to Settings > Scheduled Jobs. The Scheduled Jobs window displays.

Filter by name or Status: Any, Running, Failed, Idle, or Manual.
To run the scheduled job manually, click Start. The job is executed immediately.
To run the scheduled job automatically, select the job and set the desired time interval in the Settings tab. Each scheduled job's run time displays in the Start Date field.

Details tab

The Details tab lets you run the scheduled job manually. Click Start, and the job is executed immediately.

History tab

The History tab lets you monitor the status and results when a scheduled job is executed. If a job fails, information about it displays under the Message column.

Settings tab

The Settings tab lets you set the desired time interval. Each scheduled job's run time displays in the Start Date field.

If you select Manual, the Start Date field does not display, and the job is inactive. Inactive jobs must be started manually.
The other options are counted as active status and display the Start Date field.
If you modify any fields, click Save Scheduled Job (or Revert to remove your changes).

Built-in scheduled jobs

Archive Function – Sets how often the system archives information after the publication period expires with the Archive Function job.

📘
Note
There can be a delay between when information is unpublished and when it appears in the archive. This may occur if the archiving job is run only once a day.
Automatic Emptying of Trash – Sets how often your trash empties. With automatic emptying, content in trash older than 30 days is permanently deleted by default. You can also manually delete Trash permanently. The job is enabled by default and set to run weekly.
Change Log Auto Truncate – Deletes items from the change log that are more than one month old and do not have any dependencies registered against them by another part of CMS (for example, Mirroring). The job is enabled by default and set to run weekly.

📘
Note
Earlier versions of this description referenced Mirroring as an example dependency source. Mirroring was removed in CMS 13. If your implementation includes custom subsystems that register change log dependencies, those entries are preserved regardless of age until the dependency is released.
Clear Thumbnail Properties – Clears generated thumbnail images in the Products list and Media list views and add them again. Run this job manually if you experience problems with refreshing thumbnails, such as on the website and BLOB-supported content.
Link Validation – Checks links on your website to identify broken links. The system tries to contact the target for the link to verify that it is responding. Links are returned only if they are unchecked or checked earlier than when the job started. The job continues until no more unchecked links are received from the database. If many consecutive errors are found for external links, in case of a general network problem with the server running the site, the job stops. The result of the link validation job is a report called Link Status in the Optimizely CMS Report Center.
Monitored Tasks Auto Truncate – Truncates the status of monitored tasks. It is a clean-up job that deletes 30 days of statuses of monitored and completed jobs. The job is enabled by default and set to run weekly.
Notification Dispatcher – Sends notifications, such as email notifications, from Optimizely CMS to users regularly. The Projects feature uses it to send out email notifications of new or updated comments and replies posted in projects and also by approve content to send out email notifications on review requests; see Which actions trigger a notification? for a list of the actions that will generate a notification. Emails are only sent out if an action has triggered a notification since the job was last executed. The job is enabled by default and set to run every 30 minutes.
Notification Message Truncate – Truncates or deletes 3-month-old notification messages that could not be sent and are still in the system. The job is enabled by default and set to run every day.
Optimizely Graph Delta Synchronization – Sets how often the system syncs the changed content. Only content modified since the last sync is processed. The job now produces improved execution logs that include:
- Document counts – Total number of documents processed in each indexing step.
- Skipped items – Items excluded from indexing, with the reason for exclusion.
- Failed items – Items that could not be indexed, with error details.
- Timestamps – Start and end times for each indexing step, making it easier to identify bottlenecks. Check the History tab after each execution to review the detailed log output.
Optimizely Graph Full Synchronization – Sets how often the system syncs all content and content types. A full sync reindexes the entire content tree regardless of change history. The job produces the same improved execution logs as the Delta Synchronization job, including document counts, skipped and failed item details, and per-step timestamps. Review the History tab after execution for a full indexing report.
Optimizely Graph Smooth Rebuild Synchronization – Sets how often the system syncs Optimizely Graph Smooth Rebuild data. A smooth rebuild reindexes content into a new index in the background and then switches traffic over atomically, avoiding downtime during a full reindex. Like the other Graph sync jobs, this job logs document counts, skipped items, failed items, and timestamps for each indexing step. Review the History tab for the execution report.
Publish Delayed Content Versions – Sets how often the system checks for content versions with a specific future publication date and time. The job is enabled by default and set to run hourly.
Remove Abandoned BLOBs – CMS can store media files in a cloud service instead of the website's database. When you delete CMS files, this job ensures the stored data is deleted from the BLOB provider. The job is enabled by default and set to run weekly.
Remove Permanent Editing – Clears the Permanently Mark as Being Edited marking of pages in the edit view (if editors have forgotten to remove the marking). The job is enabled by default and set to run hourly.
Remove Unrelated Content Assets – Deletes content folders containing media related to deleted items. The job is enabled by default and set to run weekly.
Synchronize with Graph – Triggers an immediate, direct synchronization of content to Optimizely Graph. Unlike the scheduled Graph sync jobs, this operation:
- Bypasses the indexing queue — content is pushed directly to Graph without waiting for queue processing.
- Skips hash validation — all selected content is re-sent to Graph regardless of whether it has changed since the last sync. Use this job when you need to force a full re-push of content outside the normal scheduled sync cycle, for example after a schema change or to resolve indexing discrepancies.
📘
Note
Because hash validation is skipped, this job may produce higher API load than the standard delta or smooth rebuild jobs. Use it selectively rather than as a replacement for the scheduled sync jobs.
Trim Content Versions – Specifies whether the trim of content versions is active or inactive, and how often the job should be run. The job removes previously published versions so the number of versions per content does not exceed the configuration setting. The default value is 20 versions. You can decrease the value of the Maximum number of versions by going to Admin > Config > System Configuration > Editing tab. You can see the Maximum number of versions setting.

Optimizely Commerce Connect-related scheduled jobs

Installing Optimizely Commerce Connect adds scheduled jobs to your implementation. See Scheduled jobs in the Optimizely Commerce Connect section.

Orphaned scheduled jobs

When a NuGet package that registered one or more scheduled jobs is removed from your project — for example, Geta.NotFoundHandler, EPiServer.Forms.UI, or similar add-ons — the corresponding job records remain in the tblScheduledItem database table. These orphaned records are harmless: the CMS will not attempt to execute them if the backing type can no longer be resolved, and they do not cause runtime errors.

However, they will appear in the Scheduled Jobs list with no associated functionality. You can safely delete orphaned job records from the Scheduled Jobs UI or directly from tblScheduledItem if you want to keep the list clean.

Other scheduled jobs

Customized modules and add-ons may have their own specific scheduled jobs. See the technical documentation for each module to find out more.
