Use the Table Rebuild utility to recreate a table, database, or entire disk on a single AMP under the following conditions:
- The table structure or data is damaged because of a software problem, head crash, power failure, or other malfunction.
- The affected tables are enabled for fallback protection.
Table rebuild can create all of the following on an AMP-by-AMP basis:
- Primary or fallback portions of a table.
- An entire table (both primary and fallback portions).
- All tables in a database.
- All tables on an individual AMP.
The Table Rebuild utility can also remove inconsistencies in stored procedure tables in a database. A database system engineer, field engineer, or system support representative usually runs the Table Rebuild utility.
