ABSTRACT:
A system and method for assessing the activity level of a database management system. The number of page fix operations performed by execution units of a database management system can be counted and used to compute a measure for the activity level of the database management system. In one embodiment of the invention, multiple counters are used to count the page fix operations. This and other embodiments of the invention facilitate activity level assessment without incurring significant performance penalty.
