Resetting base values

Database Advisor lets you reset base values by viewing the historical base values for past utility executions and selecting a set of base values from the list. Base values are reset to the values for the selected utility execution.

Error
Warning

The circumstances under which you should reset base values must be exceptional. For example, you may want to reset base values after recovering a database. For guidance about resetting base values, contact BMC Customer Support.

To reset base values after running IDCAMS repro, IMS application loads, and IBM recovery (DFSURDB0), include the //CPC$INCL DD DUMMY DD statement in your job step. The presence of the DD statement causes base values to be reset the next time that data is collected for the DBDs (the next time that the ENDOFDAY function is executed).

To reset base values in the console

  1. In the Navigation window, right-click the object for which you want to reset base values and choose Analysis Options > Base Values.The Base Values window (Figure) is displayed.
  2. On the History tab, click List.A list of the utility executions (Figure) that have been run on the selected object is displayed.
  3. Select a utility execution, and click View.The History Base Values dialog box (Figure) is displayed.

  4. To reset base values for the selected object, click Reset.The base values are reset and are used during analysis.
