Specifies the cost profile used by Vantage. 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.
0 through 32760
|IF CostProfileId is…||THEN…|
|0||Vantage uses the default cost profile for the current combination of hardware and database release. The default may differ from release to release, so this field should remain set to zero under most circumstances.|
|greater than 0||Vantage uses the cost profile identified by the specified number.|
Changes Take Effect
For new sessions after the DBS Control Record has been written. Changing this setting does not cause any running sessions to change cost profiles.
The CostProfileId field is preserved across upgrades. If the field is set to anything other than zero, it can result in an inappropriate cost profile being used when the system is upgraded.
