The values for system-wide defaults are distributed across the configuration via the
following:
If your system is set for Universal hash code, the:
DBC.Hosts system table
tdlocaledef.txt file
Globally Distributed Objects (GDOs), which store global configuration settings that
are automatically propagated to all nodes of an MPP system. The system uses several
GDOs internally, each storing configuration settings that are specific to different
system functions or utilities. For example, there are GDOs to store the settings managed
by the DBS Control, Cufconfig, Gtwcontrol, and Control GDO Editor utilities. GDOs
are used to store configuration settings for Teradata dynamic workload management
software and TASM, and many other Teradata Database functions. Use the gdomview command-line
tool from the system console to view a history of the changes made to the GDO. You
can access the gdomview online documentation from a system console using the ‘man’
and ‘pdehelp’ commands.
