Performing a Dynamic Configuration
Follow the steps below to dynamically configure DTS changes. Refer to Chapter 5,
“Configuring Serial Devices (for Host-Based Management),” and Chapter 6, “Configuring
Serial Devices (for PC-Based Management),” for more detailed steps on the DTS
configuration process using NMMGR for host-based and PC-based DTC management,
respectively.
NMMGR can keep up to 70 changes. This means that you can change a maximum of 70
different screens before you invoke DTCCNTRL. After the 64th change NMMGR displays a
warning that tells you the limit is near. If more than 70 changes are made NMMGR
warns that the current change will not take effect using DTCCNTRL. Those changes made
after 70 entries will not be kept and can not be made dynamically. After DTCCNTRL is
invoked and the changes were successful, NMMGR can again keep up to 70 new
changes. Those changes that were not successful will be saved so they can be retried at a
later time. When a new DTC is added NMMGR considers this to be one change even if
you save data on many screens to configure this DTC.
1. Run the NMMGR program and make all desired DTS configuration changes. The
network management configuration file must be NMCONFIG.PUB.SYS for the
configuration changes to become active dynamically.
NOTE If you are changing profile characteristics, you can see which ldevs and DTCs will be
affected by the change by pressing the
[Assoc Ldevs]
function key on the profile
screen corresponding to the profile you are changing. After pressing this key, you will
see a list of all ldevs using this profile in the DTCs configured in DTS. Refer to
Chapter 7, “Terminal and Printer Profiles,” for more information.
2. After successful validation and cross-validation, NMMGR will prompt you as to
whether you want DTS changes to take effect now. The following prompt will appear:
If you type Y, dynamic configuration changes will take effect now. NMMGR calls
DTCCNTRL which dynamically implements the DTS changes made in NMMGR.
If you type N, dynamic configuration changes will not take effect now. Your changes
will take effect the next time dynamic configuration is invoked, a DTS shutdown/
restart is performed, or the system is rebooted. Dynamic configuration changes can
be implemented later by calling DTCCNTRL from the CI prompt any time thereafter.
Do you want DTS changes to be become active now (Y/N)?
Y = all changes made take effect now
N = all changes made will take effect upon next dynamic
configuration or system boot
