WebSphere Application Server for z/OS uses a SAF-compliant security product for its operating system security interfaces. The WebSphere Application Server for z/OS documentation assumes the use of z/OS Security Server (RACF). If you use another security product, consult the vendor for more information.
All z/OS systems in a sysplex must have access to consistent security information--shared RACF database or equivalent. If a shared security database is not used, you are responsible for ensuring that all WebSphere Application Server for z/OS security definitions are in effect on all systems in the sysplex.
