CURRENT MDC ROLLOUT MODE special register

The CURRENT MDC ROLLOUT MODE special register specifies the behavior on multidimensional clustering (MDC) tables of DELETE statements that qualify for rollout processing.

The default value of this register is determined by the DB2_MDC_ROLLOUT registry variable. The value can be changed by invoking the SET CURRENT MDC ROLLOUT MODE statement. When the CURRENT MDC ROLLOUT MODE special register is set to a particular value, the execution behavior of subsequent DELETE statements that qualify for rollout is impacted. The DELETE statement does not need to be recompiled for the behavior to change.
