The number of disk page IDs that are retained for each user
These IDs are used in computing the DKRR statistic. LRUPG can range from 0 to 255. A value of 0 indicates that no DKRR statistics should be kept. Refer to Using system statistics for more information on the DKRR statistic.
Note: LRUPG values greater than 0 (the default) are not recommended due to their significant performance penalty and the fact that the information provided is no longer very useful.
