Auxiliary Address Space User ID

You must define a security system user ID for the auxiliary address space. The user ID can be the same as the one defined for the SCS address space. The user ID must have read access to the data sets allocated by the auxiliary address space JCL procedure. If the user ID for the auxiliary address space is different from the user ID for the SCS address space, it does not need an OMVS segment.

The auxiliary address space is always started as a started task. Use your security system to associate a user ID with the auxiliary address space started task.
