| 12 | :caption: Enable session persistence |
| 13 | :linenos: |
| 14 | |
| 15 | policy stop |
| 16 | features enable session-persistence |
| 17 | |
| 18 | The configuration is located at: |
| 19 | |
| 20 | - *$POLICY_HOME/config/feature-session-persistence.properties* |
| 21 | |
| 22 | Each controller that wants to be started with persistence should contain the following line in its *<controller-name>-controller.properties* |
| 23 | |
| 24 | - *persistence.type=auto* |

| 33 | Facts will survive PDP-D restart using the native drools capabilities and introduce a performance overhead. |
