Delete resources

A specific version of a resource, meaning a process or decision definition, can be deleted from the Processes and Decisions pages.

Delete process definition from Processes page

To delete a process definition from the Processes page, take the following steps:

1. On the Processes page, select a specific process version by filtering by process name and version.

note

In Operate, you can only delete a process definition version that has no running instances; the Delete button is disabled otherwise. You can cancel or resolve running process instances from the process instances list or from the process instance detail page.

A process definition that was deleted while it still had running instances (for example, using the delete resource command) is draining. Operate marks it with a Draining tag and removes it automatically once its last instance finishes. To see which instances are keeping it alive, open the definition and view its running instances.

2. Click the Delete button at the top right.

3. Confirm the delete operation by checking the checkbox and clicking Delete.

note

Deleting a process definition will permanently remove it and will impact the following:

• All the deleted process definition's finished process instances will be deleted from the application.
• All decision and process instances referenced by the deleted process instances will be deleted.
• If a process definition contains user tasks, they will be deleted from Tasklist.

4. The progress of the delete operation can be seen in the Operations panel on the right side of the screen.

Delete decision definition from Decisions Page

1. On the Decisions page, select a specific decision version by filtering by decision name and version.

2. Click the Delete button at the top right.

3. Confirm the delete operation by checking the checkbox and clicking Delete.

note

Deleting a decision definition will delete the DRD and will impact the following:

• By deleting a decision definition, you will be deleting the DRD which contains this decision definition. All other decision tables and literal expressions that are part of the DRD will also be deleted.
• Deleting the only existing version of a decision definition could result in process incidents.

4. The progress of the delete operation can be seen in the Operations panel on the right side of the screen.
