Clean up data management job history

  • Статья

As of September 2023, Data Management job history entries and related staging table data that are older than 90 days are automatically deleted. To configure a job history retention period of less than 90 days, customers can use the Job history cleanup batch job.

Clean up data

  1. Go to Data management > Job history cleanup.
  2. In the Job history pane, set the Number of days to retain history, Number of hours to execute the job, and Batch job recurrence fields.
  3. To schedule the job to run regularly in the background, select the Batch processing field.
  4. To define a recurrence, select Recurrence, and then, in Recurrence definition, select No end date.

Note

To clean large staging tables, we recommend that you set an execution time of six hours and a batch recurrence of at least once per day.

Execution history cleanup batch error

If a Job history cleanup batch job has already been scheduled, it must be deleted before a new recurrence can be rescheduled. If you try to schedule a batch recurrence when one has already been scheduled, an error occurs. To address the error, follow these steps.

  1. Go to System administration > Inquiries > Batch jobs.
  2. Search for the description Job history cleanup.
  3. Delete batch jobs that are in a Waiting state.
  4. If a batch job is in an Executing state, you can either cancel it or select Remove recurrence. The Remove recurrence function removes the batch job schedule after the current cleanup execution is completed.
  5. After the job is either deleted or in an Ended state, create a new batch job recurrence.

Cleanup job history in cloud environments

Past job history cleanup activity is tracked in the DMFStagingHistoryCleanupTable table. It can be viewed by clicking Cleanup job history on the Job history cleanup page.

There are two types of cleanup job are recorded on this page:

  • Records with positive values in the Hours to execute the job and Retain job history columns correspond to runs of the Job history cleanup batch job. This is the cleanup job that is configured using the Job history cleanup page. To improve cleanup performance, this job has been updated to target only parent DMF execution records. Staging table data and other data related to the execution aren't deleted by this job. Only execution records older than the configured Retain job history value are deleted.
  • Records with -1 in the Retain job history column correspond to an automatic background cleanup job. This job runs automatically and removes all child records from staging tables and other DMF-related tables where the parent execution record has been deleted by the Job history cleanup batch job (1).

These two jobs work in tandem:

  • Job history cleanup batch job removes execution records which have gone out of the configured retention period.
  • Automatic background cleanup job removes all staging data and ancillary job data associated with those executions.
