Utilities
Utilities Descriptions
CLKUTIL
CLKUTIL reads and sets the hardware clock. The clock is used for timestamps and time
displays. It is usually set to Greenwich Mean Time (GMT). CLKUTIL is a standalone utility,
and runs only on the physical console at the ISL prompt.

DEBUG
DEBUG is used primarily by system programmers, who use it to set breakpoints within
programs, and to display and modify data stacks and registers. Access through the DEBUG
command is available only to users with privileged mode (PM) capability. Nonprivileged
users can get limited access with the ;DEBUG option of the RUN command to debug their
applications; the DEBUG utility will not allow them privileged access to the system.
CAUTION Normal MPE safeguards are bypassed in privileged mode. When attempting
to modify privileged data on disk, it is possible to destroy file integrity, or the
MPE operating system itself. Hewlett-Packard is not responsible for changes
you make to the operating system or system files. For more information, talk
to your Hewlett-Packard service representative.
DIRMIG
DIRMIG (The Directory Migration Tool) utility simplifies the migration of your environment
from MPE V/E systems to MPE/iX systems. DIRMIG uses an MPE V/E SYSDUMP tape to
transport data including the system directory (account structure), UDCs, user logging IDs,
user files and information specifically related to user volumes.
DISCFREE
The DISCFREE utility displays information about the system's free disk space, total volume
space capacity, and disk allocation for single volumes or for the whole system. It also
determines disk volume fragmentation and transient and permanent disk space limits.
DISCFREE displays disk allocation data only for mounted MPE/iX volumes, not scratched
volumes; use the DSTAT command to identify currently mounted volumes.
DISCUTIL
DISCUTIL is a standalone utility that you use to request various disk operations. Use it
with the RECOVER command of VOLUTIL to save, and subsequently recover, files from a
system that has become logically inoperable. This program can be invoked only at the
DEBUG
or
RUN PROGNAME;DEBUG
DIRMIG

or DISCFREE"[[format]][, ldev

or
