New Features of MPE/iX: Using the Hierarchical File System

User and Group Databases 

UIDs and GIDs are stored in two databases:  HPUID.PUB.SYS holds UIDs and
related user information in a user ID database, and HPGID.PUB.SYS holds
GIDs and related information in a group ID database.

These databases are privileged files that are transparent to users.  The
databases are automatically updated when you add, change, or delete users
on the system by using the following commands:

     ALTACCT
     ALTUSER
     NEWACCT
     NEWUSER
     PURGEACCT
     PURGEUSER

The system automatically creates and maintains the user and group
databases when you update to Release 5.0.

The complete user and group databases can be rebuilt using the RESTORE
command with the DIRECTORY option.  Refer to the section "Reloading
Hierarchical Directories" in Chapter 8 for more information.
