Using Resource Caching

CA Top Secret maintains a cache of permitted resources that a user has already been allowed to access. Checking for subsequent access during the life of the cache is allowed if the resource is present in the cache with a matching access level. Since the resource has already been vetted before entering the cache, subsequent accesses need not access the security file to revalidate. By making use of the cache, CA Top Secret reduces security file I/O.

The following facility control option is used in CICS-type facilities to control the resource cache:

CICSCACHE({TASKLIFE|SESSLIFE},{NOAUDIT|AUDIT},{512|1024|2048|4096})

This control option is normally set in the parameter file on your CICS facilities. However, the first two parameters may be changed dynamically while CICS is running, for testing and diagnostic purposes.
