DCE/3000 versus DCE/9000: Differences
It is assumed that readers have the basic understanding of the
differences between MPE/iX POSIX environment and a UNIX based system
environment. This section is intended to give end users some key
concepts on their first exposure to DCE/3000.
File Naming Convention
The traditional MPE directory structure is made up for a three-level
hierarchy and names for those accounts, groups, and files are all
upshipted. The addition of POSIX functionality to MPE/iX makes it
possible for DCE programs and utilities to have the same name and
location as they are used on an HP 9000. While those DCE programs can be
executed in the MPE shell environment, a similiar MPE name is also
available from the MPE CI environment. Table 1-1 lists some examples of
the similarities in names.

Managing DCE Deamons
The DCE daemons (rpcd, secd, cdsd, and so on) are run as MPE/iX jobs that
log on as manager.sys. If passwords are required, you are prompted for
them.
It is important to set the job limit high enough so that all the DCE
daemons can logon. For better performance, these daemons should run in
the CS queue. Be sure to issue the jobpri cs command at startup, to
allow these jobs to run in the C queue.
Security and Remote Login Utilities
You can use standard MPE remote login commands to perform remote DCE cell
administration; there are no DCE-integrated MPE/iX login utilities.
However, this exposes the cell administrator's password to network
attackers whenever you perform a task on a remote system. If a network
attacker obtains the password, the security of the cell's DCE services is
compromised. The most secure way to perform the cell administration is
to log in locally to each system you need to administer.
