How to Use the modDhctCfg Utility
The instructions and examples in this section describe how to use the modDhctCfg
utility. This section covers those options that our engineers think system operators
are most likely to use. Refer to Options Available With the modDhctCfg Utility (on
page 98) for examples showing how to use the various supported options.

Running the modDhctCfg Utility
Refer to the following procedures to run the modDhctCfg utility.
Note: The transaction that the utility sends is the same ModifyDhctConfiguration
transaction that was sent to the DHCT(s) the last time the DHCTs received a
ModifyDhctConfiguration transaction. The utility simply retrieves the data from the
database and re-transmits it.

Sending the ModifyDhctConfiguration Transaction to a Single DHCT
Follow these instructions to send the ModifyDhctConfiguration transaction to a
single DHCT.
1 If necessary, open an xterm window on the DNCS.
2 Type modDhctCfg [DHCT MAC address] and then press Enter. The system
single DHCT.
1 If necessary, open an xterm window on the DNCS.
2 Type modDhctCfg [DHCT MAC address] and then press Enter. The system
sends the ModifyDhctConfiguration transaction to the specified DHCT.
Note: Substitute the MAC address of the DHCT for [DHCT MAC address].
Example: modDhctCfg 00:02:DE:4A:11:92
Note: Substitute the MAC address of the DHCT for [DHCT MAC address].
Example: modDhctCfg 00:02:DE:4A:11:92
Sending the ModifyDhctConfiguration to a List of DHCTs
Follow these instructions to send the ModifyDhctConfiguration transaction to a list
of DHCTs.
1 If necessary, open an xterm window on the DNCS.
2 Type modDhctCfg [file name] and then press Enter. The system sends the
of DHCTs.
1 If necessary, open an xterm window on the DNCS.
2 Type modDhctCfg [file name] and then press Enter. The system sends the
ModifyDhctConfiguration transaction to all the DHCTs represented in the file.
Note: Substitute the name of the file you prepared for [file name].
Example: modDhctCfg modDhctCfg-in_11.13.03
Note: Substitute the name of the file you prepared for [file name].
Example: modDhctCfg modDhctCfg-in_11.13.03
Sending the ModifyDhctConfiguration Transaction with a Specified Blocking Factor
The blocking factor option specifies now many DHCT records the modDhctCfg
utility transmits as a block. When the blocking factor is not specified with the
modDhctCfg utility, the utility uses a default blocking factor of 10. When you
urgently need to use the utility to send the ModifyDhctConfiguration transaction to
a large number of DHCTs, you might want to increase the blocking factor. An
increased blocking factor has the effect of increasing the priority of the transactions.
