Monitor and manage background workflow processes
To monitor and manage processes, you must locate the process, evaluate the status, and perform any actions necessary to address problems.
Monitoring background workflows
Background workflows generate System Job rows to track their status. You can access information about these system jobs in several places within the application:
Settings > System Jobs
This will include all types of system jobs. You will need to filter rows to those where System Job Type is Workflow.
From the background workflow process
Open the background workflow definition and go to the Process Session tab. This will show only the system jobs for this background workflow.
From the row
You can edit the table form so that the navigation will include the Background Processes relationship. This will show all the system jobs that have been started in the context of the row.
If an asynchronous system job (workflow) fails several times consecutively, the system starts to postpone execution of that job for longer and longer time intervals so that the administrator or app maker can investigate and resolve the issue. Once the job starts succeeding again, it will resume executing normally.
Actions on running background workflows
While a background workflow is running, you have options to Cancel, Pause, or Postpone the workflow. If you have previously paused a workflow, you can Resume it.
Status of background workflow processes
When you view a list of background workflow processes, any individual process can have one of the following State and Status Reason values:
|Ready||Waiting for Resources|
Deleting process log rows
If your organization uses background workflows or business process flows that run frequently, the amount of process log rows can become large enough to cause performance issues as well as consume significant amounts of storage. To delete process log rows not removed sufficiently by one of the standard bulk row deletion jobs, you can use the bulk delete system jobs feature to create a custom bulk row deletion job.
Go to Settings > Data Management > Bulk Row Deletion.
From the Bulk Row Deletion area, select New.
On the Bulk Deletion Wizard start page, select Next.
In the Look for list, select System Jobs.
The following conditions are used to create a bulk row deletion job to delete process log rows:
- System Job Type Equals Workflow. This targets background workflow rows.
- Status Equals Completed. Only completed workflows are valid to run the job against.
- Status Reason Equals Succeeded. Delete successful, canceled, and failed jobs.
- Completed On Older than X Days 30. Use the Completed On column to only delete background workflow process log rows that are older than 30 days.
Set the frequency that your bulk delete job will run. You can schedule your job to run at set intervals or create a one-time bulk deletion job Using the Immediately option. In this example, a recurring job is set to run on May 21, 2018, and every 30 days thereafter.
Using the Immediately option
Notice that you have the option of performing an immediate synchronous bulk delete of the rows by selecting the Immediately option. This delete is performed with direct SQL Server execution rather than passing each row through the delete event pipeline, which can reduce the impact to system performance. This is a good option if you want to quickly clean up the extra background workflow rows instead of the bulk delete job waiting in the asynchronous queue for processing.
The Immediately option is enabled when the following conditions are true:
- Bulk delete job is for the System Jobs table.
- The search criteria has the condition System Job Type Equals Workflow.
- The user creating the bulk delete job has global depth for the delete privilege on the AsyncOperation table. The System Administrator security role has this privilege.
The synchronous bulk delete will only delete AsyncOperation rows in the completed state. A maximum of 1 million rows are processed for each invocation. You will need to execute the job multiple times if your environment has more than 1 million rows to remove.
