Data Dictionary Definitions – Archived table and databases can only be restored to a Teradata Database if the
data dictionary contains a definition of the entity to be restored.
Locks – Teradata ARC uses a utility (HUT) lock, therefore a single user cannot initiate
concurrent restore tasks. The Teradata ARC lock avoids possible conflicts when releasing
locks. To restore concurrently, supply a separate user identifier for each restore
task.
For restores of selected partitions, Teradata ARC applies a HUT write lock.
UtilVersion Match – To restore selected partitions, the archive UtilVersion must match the UtilVersion on the target system if they are both non-zero. If UtilVersion is zero on the archive, the Version on the archive must match the UtilVersion on the target system. For more information, see “Archiving Selected Partitions of PPI Tables” on page 37.
