ACEE caching

RACF® can save ACEEs (Accessor Environment Elements) using VLF (Virtual Lookaside Facility) and retrieve them for later use. z/OS® Explorer asks your security software to build multiple security environments (ACEEs) for the same user (one for each user-specific thread in the RSE thread pool), and can thus benefit from ACEE caching.

For more information on ACEE caching, see “ACEEs and VLF considerations” in the Security Server RACF System Programmer's Guide (SA22-7681).
