Resource usage data is stored in system tables and views in the DBC database. Teradata macros generate reports that display the data.

To load the resource usage views and macros, you can run the Database Initialization Program (dip) script, DIPRUM. For more information on DIPRUM, see Teradata Vantage™ - Database Utilities, B035-1102.

You can run DIP scripts one at a time or all at once by running DIPALL. DIP scripts, such as DIPRUM and DIPSYSFNC, can be executed in any order.

As with other database data, you can access resource usage data using SQL if you have the proper privileges. You can also write your own queries or macros on resource usage data.

The following table lists the topics covered by resource usage data.
