To enable object use counts, use the WITH USECOUNT option of the BEGIN/REPLACE QUERY LOGGING request. This request starts collection of object use counts in the Data Dictionary table DBC.ObjectUsage. Object use counts are disabled by default, but it is a best practice to enable them for production databases to ensure the accuracy of automated statistics.
Vantage tracks two versions of these counts, which collect identical information:
- User counts (a user can reset).
- System counts (only the system can reset).
