Run the Reconfiguration Estimator utility, reconfig_estimator, before running the Reconfiguration utility described in Reconfiguration Utility (reconfig).
Reconfiguration Estimator estimates the reconfiguration time based upon the number and size of tables on your current Teradata Database system. Reconfiguration Estimator provides time estimates for the following phases:
- Redistribution
- Deletion
- NUSI building
Reconfiguration Estimator also validates the existence of tables enumerated in the ordering lists for the redistribution and deletion phases of reconfiguration.
Reconfiguration Estimator provides the most accurate estimates for add AMP operations. Estimates for other operations, such as moving or deleting AMPs may be less accurate.
