Controls whether the system cost profile can be changed for purposes of system emulation and special-case system tuning. A cost profile is a suite of system-specific values (cost profile constants) that Vantage uses for Optimizer costing coefficients, enabling and disabling certain features, and other system settings. A cost profile can apply system-wide or be associated with a PROFILE and apply only to users assigned that PROFILE.
This field should be changed only under the direction of Teradata Support Center personnel.
