Descripción

The AUTHEXIT_CACHEREFRESH subsystem parameter refreshes the global authentication cache entries for user profile changes in RACF and authorization cache entries for external security users for resource and user profile changes. It is recommended that this security subsystem parameter is set to ALL. Removing the cache entries prevents users whose profiles are changed in RACF from accessing Db2 resources.
