Clean up the batch job table

Over time, new batch jobs are created for specific user actions, one-time jobs are run, and batch jobs are re-created. As a result, many abandoned or unused batch jobs accumulate in the system. Accumulated batch jobs can eventually lead to the growth of the batch job table and related tables. This growth can negatively affect the performance of other jobs.

In version 10.0.39 (Platform update 63), the System administration module includes a Batch job clean-up page that simplifies the process of cleaning up the batch job table. To open this page, go to System administration > Periodic tasks > Batch job clean-up.

Note

We recommend that you regularly clean up the batch job table, and that you do this cleanup outside business hours.

Run batch job cleanup

To quickly clean up the records in the batch job table, follow these steps.

  1. Go to System administration > Periodic tasks > Batch job clean-up.
  2. In the Retain jobs (days) field, specify the number of days to keep the records of batch jobs.
  3. In the Records to delete in a transaction field, input a value ranging from 1 to 200 to indicate the number of records to be deleted within a single database transaction. The associated job iterates through and removes data in batches of this size until all records are deleted. When the batch job processes a large volume of data, particularly within the parameters and information log fields of related jobs and tasks, it's advisable to enter a smaller number. This approach facilitates deletion in smaller segments and prevents the obstruction of other jobs.
  4. In the Caption field, specify the title of the batch job to be deleted. The matching process is case-insensitive and requires an exact match.
  5. In the Class field, specify the class name of a batch task for the batch job to delete.
  6. Enable the Delete by end date time field if the cleanup should consider the end date/time of the last execution to determine which batch jobs to delete. By default, the cleanup considers the creation date/time.
  7. In the Created by field, specify the user ID of the person who created the job.
  8. In the Withhold, Error, Finished, and Canceled terminal status fields, select at least one option to delete the batch jobs.
  9. Select OK.
