Teradata Parallel Data Pump

Chapter 3: Teradata TPump Commands
BEGIN LOAD
Syntax Element
statement_rate
Description
Initial maximum rate at which statements are sent to Teradata Database
per minute.
The statement rate must be a positive integer. If the statement rate is
unspecified, the rate is unlimited.
If the statement_ rate is less than the statement packing factor, Teradata
TPump sends requests smaller than the packing factor.
If the Teradata TPump Monitor is in use, the statement_rate can be
changed later on.
SLEEP
NOATOMICUPSERT
NOMONITOR
ROBUST ON/OFF
Keyword for the number of minutes to sleep.
Keyword to perform non-atomic upsert operations for UPSERT DMLs
in the job script if these UPSERT DMLs are not provided in the Atomic
UPSERT form.
Keyword to prevent Teradata TPump from checking for statement rate
changes from, or update status information for, the Teradata TPump
Monitor.
The ON parameter ensures data integrity when target tables have
identity columns.
The OFF parameter signals Teradata TPump to use simple restart logic.
In this case, restarts cause Teradata TPump to begin where the last
checkpoint occurred in a job. Any processing that occurred after the
checkpoint is redone. This method does not have the extra overhead of
the additional database writes in the Robust logic.
Caution: Certain errors may cause reprocessing, resulting in extra
error table rows due to reexecuting statements (attempting to
re-insert rows, for example). Or, if the target table allows
duplicate rows, reexecuting statements may cause extra
duplicate rows to be inserted into the target table instead of
causing extra error table rows.
Simple logic is adequate in certain DML statements that can be repeated
without changing the results of the operation. Examples of statements
that are not simple logic include the following:
• INSERTs into tables that allow duplicate rows (MULTISET tables).
• Self-referencing DML statements such as:
• “UPDATE FOO SET A=A+1...”
• “UPDATE FOO SET A = 3 WHERE A=4”
MACRODB
dbname
Keyword for database to contain any macros used by Teradata TPump.
Name of database which is to contain any macros built/used by Teradata
TPump.
This database overrides the default placement of macros into the
database which contains the log restart table.
