Authority cache

The system creates authority caches for users to provide flexibility and performance enchancement.

The system creates an authority cache for a user the first time the user accesses an object. Each time the object is accessed, the system looks for authority in the user's cache before looking at the users's profile. This results in a faster check for private authority.

The authority cache contains up to 32 private authorities to objects and up to 32 private authorities to authorization lists. The cache is updated when a user authority is granted or revoked. All user caches are cleared when the system IPL is performed.

While limited use of private authorities is recommended, the cache offers flexibility. For example, you can choose how to secure objects with less concern about the effect on system performance. This is especially true if users access the same objects repeatedly.
