Setting up an Rdb Archive History Provider

For history query purposes, an archive history provider pulls archive data into a station from a remote database on-demand (it does not persist the retrieved archive data locally, but only uses the data in the displayed query results).
Prerequisites: You are working in Workbench connected a Supervisor station.
  1. Open the rdb palette and expand the HistoryService Archive Provider folder.
  2. In the station, expand Config > Services > HistoryService.
    The HistoryService contains an Archive History Providers container.
  3. From the palette, add a RdbArchiveHistoryProvider to the Archive History Providers container under HistoryService and double-click the provider you just added.
    The component’s Property Sheet opens.

    This Property Sheet configures the Rdb Archive History Provider.

  4. Use the button to the right of the Ord to Rdbms property to open the Component Chooser, locate the relational database in your driver network and click Save.
  5. Configure Max Archive Results Per Query and Archive Limit Notifications if needed.
    Max Archive Results Per Query determines the maximum number of history records to read from the RDBMS for any history time range query that taps into it. If more history records are available beyond this limit at history query time, the Archive Limit Notifications property defines the behavior of a subset of Workbench views, but not all of them. Web Chart and HTML5 History Table views (accessible from the browser and Workbench) provide their own notification when a history query exceeds this limit. When the limit is reached for a query, in addition to the warning, you get truncated archive history results that always consider the most recent history records first.

    The Archive Limit Notifications specifies what happens when a history query made from a Workbench user connected to the station exceeds the Max Archive Results Per Query limit.

     NOTE: This setting does not apply to HTML5 history views, including HTML5 views accessed within Workbench, such as the Web Chart view. It only applies to native Workbench views that perform history queries, such as the AX History Chart or AX History Table views.
