Purge Archived Process Instances from an Orchestrator

You can purge on demand the process instances that ran during a date range you specify.

Purge archived process instances from the Runtime database of an Orchestrator in the following situations:

• You need more available space; the accumulation of archived instances is causing the performance to degrade.
• You set the Orchestrator policy to turn off automatic purging.

Follow these steps:

1. Click the Configuration tab and expand the Orchestrators node in the Configuration Browser.

   The expanded node displays all the Orchestrators in the Domain.

2. Right-click the Orchestrator that contains the archived process instances to purge, and click Lock.
3. Click the Policies tab.
4. Click the Delete Archived Instance button at the bottom of the pane.
5. In the Delete Archive Instance dialog, define the date range in which to purge archived instances.
   1. Click the From date calendar button and select Today or a start date that precedes today.
   2. Click the To date calendar button and select Today or an end date that is after today.
   3. Click OK.
6. Click Yes on the confirmation message.

   The purge process deletes all archived instances that ran during the specified date range.

7. Right-click the Orchestrator, and click Unlock.
