Process templates can be modeled so that process instances are not automatically deleted when they complete. You can explicitly delete these process instances after they complete.
You might want to keep process instances in your database, for example, to query data from process instances that are not written to the audit log, or if you want to defer the deletion of processes to off-peak times. However, old process instance data that is no longer needed can impact disk space and performance. Therefore, you should regularly delete process instance data that you no longer need or want to maintain. Make sure that you run this maintenance task at off-peak times.
You can delete completed process instances using either Business Process Choreographer Explorer, for example, to delete individual process instances, or the deleteCompletedProcessInstances administrative script to delete several process instances at once.
In Business Process Choreographer Explorer, complete the following steps to delete a process instance.
