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.
