Activating statistics collection (STATISTICS option)
Using the SETROPTS STATISTICS option does the following:
- RACF® maintains two sets of statistics in a discrete resource profile. One set counts all activity for the resource or profile. The other set counts activity for each entry in the access list. It can be difficult to compare the two sets of statistics meaningfully, unless you understand how RACF maintains the statistics. For more information, see the STATISTICS example.
- If a specific resource has unique security concerns, protect it
with a discrete profile.
To see how that resource is being accessed and how many times it is being accessed, you can initiate STATISTICS. Remember that the initiation of STATISTICS is system-wide for all discrete profiles within a particular resource class across your system. Depending on the number of discrete profiles in the various resource classes, turning on STATISTICS might negatively affect performance.
