DisableRestartableBLC

Purpose  

Determines whether a block-level compression (BLC) operation that is interrupted by a Teradata Database reset will resume automatically when the system restarts.

Field Group

General

Valid Settings

 

Setting

Description

TRUE

Disables restartable BLC. If a BLC compress or uncompress operation is interrupted by a system reset, the operation will not continue when the system restarts, and tables may be left in partially compressed states.

Additionally, BLC compress and uncompress operations are not allowed if there are any down AMPs in the current Ferret scope.

FALSE

Enables restartable BLC. If a BLC compress or uncompress operation is interrupted by a system reset, the operation continues automatically when the system restarts.

Additionally, BLC compress and uncompress operations are allowed, even if there are down AMPs in the current Ferret scope.

Default

FALSE

Changes Take Effect

After the DBS Control Record has been written.

Usage Notes  

If the value of this field is TRUE, and tables become partially compressed, you can use the COMPRESS and UNCOMPRESS commands to make the table state consistent. For more information see Chapter 13: “Ferret Utility (ferret).”

Enabling this setting requires that the NoDot0Backdown setting be TRUE, which prevents the system from being backed down to the previous release level.
