NoDot0Backdown

Purpose  

Commits Teradata Database to a point release (for example, xx.10), by allowing certain release-specific features to be enabled, preventing the system from being backed down to the corresponding major release (xx.0) without re-initializing the system on the major release.

Field Group

General

Valid Settings

 

Setting

Description

TRUE

Allows certain point-release-specific features to be enabled which will preclude backing down the system to the previous major release of Teradata Database.

Note: When this setting is TRUE, it cannot be changed to FALSE.

FALSE

Prevents certain point release features from being enabled, but allows the system to be backed down from the currently-installed point release to the corresponding major release, without requiring a sysinit.

Default

On systems that have been sysinited on a major release, the default setting is FALSE, and cannot be changed.

On systems that have been upgraded from a major release to a point release without a new system initialization, the default setting is FALSE, and can be changed. After this setting has been changed to TRUE, it cannot be reset to FALSE.

Changes Take Effect

After the DBS Control Record has been written.

Usage Notes  

Certain new features, if enabled in a point release, would preclude the system from being backed down to the corresponding major release. These feature cannot be enabled unless NoDot0Backdown is explicitly set to TRUE. After NoDot0Backdown has been set to TRUE, it cannot be modified, and the system cannot be backed down without a sysinit. For information on the features that require NoDot0Backdown to be TRUE, see the Release Definition document for this release of Teradata Database.
