Configuring the Adaptive Decision Manager service for Pega Cloud environments

Version:

Only available versions of this content are shown in the dropdown

The Adaptive Decision Manager (ADM) service predicts customer behavior by creating adaptive models based on customer responses to your offers. With adaptive models, you can ensure that your next-best-action decisions are always relevant and based on the latest customer behavior.

The following dynamic system settings control the ADM service:

decision/monitoring/daysToKeepData
This setting determines how much time elapses before Pega Platform automatically deletes a snapshot from your repository. By default, Pega Platform deletes snapshots with a time stamp older than 180 days.
decision/adm/datamart/snapshotOnUpdate
By enabling this setting, you can configure the ADM service to take snapshots every time the model is updated. If the setting is disabled, the default system behavior is to take adaptive model data snapshots at intervals that are determined by the ADM snapshot agent schedule, typically every night.
  1. In the navigation panel of Dev Studio, click Records SysAdmin Dynamic System Settings .

  2. To change how much time elapses before Pega Platform automatically deletes a snapshot from your repository, change the value of the decision/monitoring/daysToKeepData dynamic system setting.

  3. To configure the ADM service to take snapshots every time the model is updated, add the decision/adm/datamart/snapshotOnUpdate dynamic system setting:

    If you enable this option for a prolonged period, the increased number of snapshots might cause database space issues.
    1. On the Dynamic System Settings tab, click Create.

    2. On the New tab, enter a short description of the dynamic system setting.

      Take snapshots at every model update
    3. In the Owning Ruleset field, enter Pega-DecisionEngine.

    4. In the Setting Purpose field, enter decision/adm/datamart/snapshotOnUpdate.

    5. Click Create and open.

    6. On the Settings tab, in the Value field, enter true, and then click Save.

      The decision/adm/datamart/snapshotOnUpdate setting is added to the list. The ADM service starts taking adaptive model data snapshots every time the model is updated.
  4. To revert to the default snapshot schedule, disable the decision/adm/datamart/snapshotOnUpdate dynamic system setting:

    1. On the Dynamic System Settings tab, click the decision/adm/datamart/snapshotOnUpdate setting.

    2. On the Settings tab, in the Value field, enter false, and then click Save.
