The Teradata Tools and Utilities programs that perform tasks such as bulk data loads (FastLoad, MultiLoad, BTEQ), bulk data exports (FastExport, BTEQ), stream data loads (Teradata Parallel Data Pump), both data loads and data exports (Teradata Parallel Transporter) place locks at different levels and severities on database resources. See About Locking Levels and About Locking Severity for details of locking levels and severities.

Locks Placed on Database Resources by Teradata Tools and Utilities

The client utilities place the following basic types of locks on database resources:
  • Standard database locks

    All of the client data loading and exporting utilities use standard database transaction locks (see Database Locks, Two-Phase Locking, and Serializability).

    For details about when the database locks that client utilities place and release on resources in the database, see the following Teradata Tools and Utilities manuals:
