A restore operation uses an exclusive HUT lock when data tables are restored.
- To restore an entire database, Teradata ARC places the exclusive lock at the database level.
- To restore selected tables, Teradata ARC places the exclusive lock on each table before it starts to restore the table.
- To restore (or copy) selected partitions of PPI tables, Teradata ARC uses a write lock.
- To restore selected partitions of PPI tables with GROUP READ LOCK, the entire table locks rather than a part of the table.
