Purge Event-based Data Associated with Units

You can purge event-based data associated with specific units. You cannot purge data associated with units if one or more of the following tables have been selected on the Tables tab:

  • Events

  • GB_RSum

  • Production_Starts

  • Timed_Event_Details

  • User_Defined_Events

  • Waste_Event_Details

To configure a data purge for selected units

  1. Click Start, point to All Programs, point to Proficy Plant Applications Database Purge, and click Plant Applications Database Purge. The Plant Applications Purge Configuration dialog box appears.

  1. In the Max Purge Time box, enter the maximum number of minutes you want the purge to run.

    Max Purge Time is the maximum number of minutes that the purge will run. The program checks the maximum purge time only after the number of records per batch has been purged for a selected table, unit or variable. Even if the maximum purge time expires before the specified number of records has been purged, the batch will still complete.

     

  2. On the Units (Event Based) tab, click Search. The Search Production Unit dialog box appears which you use to select the production units.

NOTE: The retention period and records per batch default to the numbers in the Retention (Months) and Records Per Batch fields at the bottom of the Plant Applications Purge Configuration dialog box.

NOTE: To delete one or more units, select the unit(s) and press DELETE.

  1. If necessary, change the retention period and the records per batch. For more information, see the topic Editing retention periods and records per batch.

  2. If desired, click the Tables or Variables (Time Based) tabs to purge data associated with units or variables. For instructions on purging data from specific tables, see the topic Purge data for selected tables. For instructions on purging data associated with variables, see the topic Purge time-based data for selected variables.

  3. Save your configuration. For detailed instruction on saving a configuration, see the topic Save a purge configuration.

NOTE: You must save your configuration before you can run a purge.
