Dynamic Configuration
Dynamic configurationenables you to apply a select set of DTS
configuration changes made in NMMGR without rebooting the system. Such
configuration changes include adding or deleting terminals, printers and
DTCs, changing most configuration parameters of terminals, printers and
DTCs. See Table 4-1 for a complete list of configuration changes
that can be modified dynamically (this includes changes that require
additional actions, such as rebooting the DTC, before changes take
effect).
All operations that delete ldevs are non-destructive. This means that if
an ldev to be deleted is in use, then the delete is not performed. You
must take the appropriate action to free the device. For example, you
must stop the spooler on a spooled serial printer or log off the session
on a terminal ldev. If multiple ldevs are deleted, then only free ldevs
are deleted. Those ldevs that were not free will be processed again the
next time DTCCNTRL is invoked.
Most changes will not affect current active sessions or users. Only
those changes that require a reset of the DTC or DTC card will affect
active sessions or users. A DTC reset is only required when the change
is to a DTC characteristic, such as, adding a card or changing a DTC CPU
parameter, such as, the DTC IP address or SNMP data. Users on other DTCs
are not affected.
Some changes will require additional steps to complete once DTCCNTRL has
made the desired changes. These possible additional steps are: logoff
any sessions or close any jobs that access the changed devices, stop and
restart the spooler if the device is a printer, stop and the start
X.25/PADSUP, reboot or reset the DTC. DTCCNTRL will display a message
when these steps are necessary and tell you which DTCs are affected.

NMCONFIG and NMCONFIX Files
Dynamic Configuration uses both files NMCONFIG.PUB.SYS and
NMCONFIX.PUB.SYS to manage the devices created by the DTS subsystem.
When users wish to make any dynamic change, NMMGR will be used to modify
the configuration in NMCONFIG.PUB.SYS. When DTCCNTRL is invoked, either
within or from outside of NMMGR, NMCONFIG will be compared to NMCONFIX
and the desired changes will be made to the system configuration. When
the operation has completed successfully, the changes will be written to
NMCONFIX. The configuration in NMCONFIX will always match the actual
configuration of the DTS subsystem.
If any errors are encountered, then information will be saved in the
NMCONFIG file that will allow DTCCNTRL to be re-invoked to complete the
changes at a later time. If an operation is partially successful, then
those changes that are successful will be written to NMCONFIX. For
example, if you delete two ldevs and the second ldev can't be deleted
because it is in use, then DTCCNTRL will save information that will allow
the second ldev to be deleted once the device is no longer in use.
CAUTION If ANY other configuration file is copied to NMCONFIG.PUB.SYS or
NMCONFIX.PUB.SYS then dynamic configuration will be disabled
until a DTS shutdown and restart is done or the system is
rebooted. This includes other files from the same system or
files copied from other systems.
If there is some operation that fails, and you wish to undo the change,
you can use NMMGR to change the appropriate screens back to what they
were and then invoke DTCCNTRL.
Compressing the Configuration Files
As your configuration grows and changes, you may find it necessary to
compress or expand your configuration file. When you add items in a
file, records are added sequentially from the beginning of the file. If
you delete items from a configuration file, the records are not
immediately recovered, so the middle of the file may contain unused
records. These unused records in the middle of the file are not
available for reuse. By compressing the file, you cause all data to be
stored in a contiguous block of records at the beginning of the file.
This frees the unused records to be reused.
Compress the files by accessing the Compress screen in NMMGR from the
utilities menu. To recover unused records enter 0 in the Number of
Additional Records field and press the [Compress File] function key. If
you enter a positive number, the number of free records will be increased
by the number entered. If you enter a negative number, the number of
free records will be decreased by the entered number. The maximum file
size limit is 65,535 records.
NOTE If you compress the NMCONFIG.PUB.SYS file you must also compress
the NMCONFIX.PUB.SYS file. You will be allowed to compress the
NMCONFIX.PUB.SYS file, but will not be allowed to modify any
records.
See the Using the Node Management Services Utilities manual (32922-90041)
for additional information on how to compress the configuration files.
