Confluence 5.3 has reached end of life
Check out the [latest version] of the documentation
The administration console allows you to schedule various administrative jobs in Confluence, so that they are executed at regular time intervals. The types of jobs which can be scheduled cover:
- Confluence site backups
- Storage optimisation jobs to clear Confluence's temporary files and caches
- Index optimisation jobs to ensure Confluence's search index is up to date
- Mail queue optimisation jobs to ensure Confluence's mail queue is maintained and notifications have been sent.
You need to have System Administrator permissions in order to configure and execute jobs.
Accessing Confluence's Scheduled Jobs Configuration
To access Confluence's Scheduled Jobs configuration page:
- Choose the cog icon at top right of the screen, then choose Confluence Admin.
- Choose 'Scheduled Jobs' to open the 'Scheduled Jobs' page. For each job listed down this page, the following information is shown:
- Job — the name of a job.
- Status — the job's status, which is either 'Scheduled' (it it is currently enabled) or 'Disabled'. See below for details on disabling or re-enabling a job.
- Last Execution — the date and time when the job was last executed. This field will be empty of the job was never executed.
- Next Execution — the date and time when the job is next scheduled to be executed. This field will contain dash symbol ('-') if the job is disabled.
- Avg. Duration — the length of time (in milliseconds) that it took to complete the job's last execution.
- Actions — allows you to configure the job, execute it manually, view a history of previous executions or disable the job.
The information on this page does not apply to Confluence OnDemand.

Refer to 'Types of Jobs' (below) for detailed descriptions about each job.
- Enter an appropriate cron expression to define the frequency with which the job is executed.
Refer to 'Cron Expressions' (below) for more details about their syntax. To revert the job's schedule back to its default settings, click the 'Default' button.
- Click 'Save' to record your job's new schedule.

- Access the 'Scheduled Jobs' configuration page (above).
- Locate the job whose execution history you wish to view and click the 'History' link.
If a job has not completed at least one execution, its 'History' link will not be available.
Refer to 'Types of Jobs' (below) for detailed descriptions about each job.
The 'History for job' dialog box opens, showing a list of previous executions of the job in reverse chronological order, including the:- Start date and time

Types of Jobs
Job Name | Description | Execution Behaviour | Default Schedule |
---|---|---|---|
Back Up Confluence | Performs a backup of your entire Confluence site. | Per cluster | At 2am every day |
Check Cluster Safety | For clustered Confluence installations, this job ensures that only one Confluence instance in the cluster writes to the database at a time. | Per cluster | Every 30 seconds |
Clean Index Queue | Triggers a periodical clean of the index queue to ensure that its size does NOT grow indefinitely. | Per cluster | At 2am every day |
Clean Temporary Directory | Cleans up temporary files generated in the 'temp' subdirectory of the Confluence home directory. This temp directory may be created by exports etc. | Per node | At 4am every day |
Clear Expired Mail Errors | Clears notification errors in the mail error queue. A notification error is sent to the mail error queue whenever the notification fails to be sent due to an error. | Per cluster | At 3am every day |
Clear Expired Remember Me Tokens | Clears all expired 'Remember Me' tokens from the Confluence site. Remember Me tokens expire after two weeks. | Per cluster | On the 20th of each month |
Email Daily Reports | Emails a daily summary report of all Confluence changes to all subscribers. | Per cluster | At 12am every day |
Flush Did You Mean Index | Note: The 'Did You Mean' feature is no longer available in Confluence. This job is therefore redundant, and will be removed at some time in the future. Flushes changes to the 'Did You Mean' index, which keeps the 'Did You Mean' feature up to date. Confluence records each content update in the 'Did You Mean' index. | Per node | Every 2 hours from 12 am |
Flush Index Queue | Flushes changes to Confluence's index so that Confluence's search results are up to date. Confluence records each content update in its search index. | Per node | Every minute |
Flush Local Task Queue | Flushes the local task queue. (These are internal Confluence tasks that are typically flushed at a high frequency.) | Per node | Every minute |
Flush Mail Queue | Sends notifications that have been queued up in the mail queue. | Per cluster | Every minute |
Flush Task Queue | Flushes the task queue. (These are internal Confluence tasks that are typically flushed at a high frequency.) | Per node | Every minute |
Optimise Indexing | Compacts the confluence indexes to maintain searching performance. | Per node | At 3am and 3pm every day |
Poll Mail | Polls POP accounts on all spaces that have them configured. | Per cluster | Every minute |
Cron Expressions
A cron expression is a string of 6-7 'time interval' fields that defines the frequency with which a job is executed. Each of these fields can be expressed as either a numerical value or a special character and each field is separated by at least one space or tab character.
The table below is shows the order of time interval fields in a cron expression and each field's permitted numerical values.
You can specify a special character instead of a numerical value for any field in the cron expression to provide flexibility in defining a job's frequency. Common special characters include:
- '*' — a 'wild card' that indicates 'all permitted values'.
- '?' — indicates 'ignore this time interval' in the cron expression. That is, the cron expression will not be bound by the time interval (such as 'Month', 'Day of week' or 'Year') to which this character is specified.
For more information about cron expressions, please refer to the Cron Trigger tutorial on the Quartz website.
Order in cron | Time interval | Permitted | Required? |
---|---|---|---|
1 | Seconds | 0-59 | Yes |
2 | Minutes | 0-59 | Yes |
3 | Hours | 0-23 | Yes |
4 | Day of month | 1-31 | Yes |
5 | Month | 1-12 or JAN-DEC | Yes |
6 | Day of week | 1-7 or SUN-SAT | Yes |
7 | Year | 1970-2099 | No |
* Excluding special characters.
