Salesforce imposes a limit of 5 on the number of concurrent Apex batch jobs. This includes:
-
Daily batches controlled with HCM Configure settings:
- Action Creation
- Action Digest
- Action Emails Send
- Handle Future Job History Dating
- Handle Future Salary Dating
- Handle Leavers
- Hold Absence Balances
- HR Request Finalize
- Internal Communications Confirmation
- Update Is Manager Field
- Stock Option Vesting
- Anonymize Surveys
- Reuse Surveys
- Update Survey Completion
- Recruit daily batch for Approval Reminders, controlled with the Recruit Configuration Reminder Email Sent Time.
- Batches triggered by edits, for example for sharing and Action Events.
- Scheduled reports and dashboards.
Optimize performance by:
- Staggering start times for configurable batches, wherever possible ensuring there is time for each batch to run to completion before the next one starts.
- Agreeing the order and timing of execution with administrators and HR Managers, ensuring batches run so the results are ready when needed.
