Note: The checkDB script makes no database changes when run with no options or
with the -v option. The script may change the database when run with the -f or -F
options. Refer to Run the checkDB Script (on page
with the -v option. The script may change the database when run with the -f or -F
options. Refer to Run the checkDB Script (on page

concerning the options associated with the checkDB script.
The deleteDhct Utility
When used with the -f or -F options, the checkDB script calls the deleteDhct utility in
order to delete DHCT records from the database. The logic of the checkDB script is
such that all references to the deleteDhct utility occur automatically; no user
intervention is required. The deleteDhct utility is included on the DBDS Utility CD.

We designed the deleteDhct utility to completely delete DHCT records from the
DNCS database. It deletes a single DHCT or can delete all DHCTs in a list containing
DHCT MAC addresses that are presented in a text file.

DHCT MAC addresses that are presented in a text file.
The logic in the deleteDhct utility is very good at finding all database rows in all the
different DHCT tables that contain or used to contain records for the specified
DHCT(s). The deleteDhct utility deletes orphaned DHCT records. While orphaned
DHCT records are less common now than they have been in the past, at one time
duplicate database rows were generated for RMA DHCTs when they were returned
from repair with a changed secure_micro address.
