Dynamic Conﬁguration and DTS Shutdown/Restart

Performing a Dynamic Conﬁguration

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”.
