• Dynamic configuration operation specified:
:DTCCNTRL func=dynconf
Refer to Chapter 5, “Configuring Serial Devices (for Host-Based Management),” and
Chapter 6, “Configuring Serial Devices (for PC-Based Management),” for more
information on actions required for changes to take effect.
NOTE You must have made all desired DTS changes in NMMGR first before invoking DTCCNTRL
from the CI prompt.
NOTE To automatically add/configure a host-based managed DTC to DTS without needing to
specify detailed configuration information such as DTC cards/boards and ldevs, refer to
Chapter 3, “Automatic Configuration of DTCs.” To manage/dynamically configure
host-based X.25 links, refer to the Configuring and Managing Host-Based X.25 Links
manual.
Using NMSTART
When NMMGR is run, one of the first actions it does is to look for an ASCII file called
NMSTART.PUB.SYS. If this file is found, NMMGR will read the contents and attempt to
execute the commands in the file.
A command can be placed in the file that will control the display of the question “Do you
want DTS changes to become active now (Y/N)?” when validation is complete. The
command has the following format:
DTSDYNCONF [OFF|ON|PERMOFF]
If NMMGR is run from a session and starts in maintenance mode, and the DTSDYNCONF
command has not been called, DTCCNTRL will not be invoked and the prompt will not
appear even if there are DTS changes. If NMMGR is started in screen mode and you
switch to maintenance mode at the command line, then the default is OFF.
When DTSDYNCONF is set to OFF, the question and prompt will appear. NMMGR will wait
for a response.
When DTSDYNCONF is set to ON, and NMMGR is run from a session, the question will be
displayed but DTCCNTRL is invoked without waiting for a response.
When DTSCYNCONF is set to PERMOFF, NMMGR will never display the question or invoke
DTCCNTRL.
When NMMGR is run from a job, NMMGR, will run in maintenance mode and accept
commands one line at a time. In this case, the “DTS changes” question will not be
displayed unless one of the commands is “DTSDYNCONF ON”.
