Invoking a user-supplied external security manager

CICSPlex® SM provides an interface to an external security manager (ESM), which can be user-supplied or can be Resource Access Control Facility (RACF®).

On the return from any user-supplied program, CICSPlex SM must always receive control in primary-space translation mode, with the original contents of all access registers restored, and with all general-purpose registers restored (except for those which provide return codes or linkage information). For information about translation modes, see z/Architecture Principles of Operation.

Note: This information is intended primarily for non-RACF users. For information about security processing using RACF, refer to Implementing CICSPlex SM security.
