UAMS

UAMS is designed to provide a fully self-contained system for user security. The subsystem allows you to define user IDs for each user of your regions. User IDs provide logon and password checking and can be added, deleted, or updated.

You can use UAMS to define:

Each user ID separately
A group ID to be used as a model for each user that requires similar access and authority

UAMS by itself is independent of any external security system. For example, passwords stored in UAMS are not synchronized with RACF.

Multiple regions can share a single UAMS data set.
