Invoking Teradata TPump
Table 12: Run-time Parameters/Systems
Channel-attached Network-attached Description
BRIEF -b Specifies reduced print output, which limits Teradata
TPump printout to the minimal information required to
determine the success of the job:
• Header information
• Logon/logoff information
• Candidate records
• Insert, update, and delete results
• Error table counts
BUFFERS =
numberofbuffers
CHARSET =
charactersetname
-f numberofbuffers Sets the number of request buffers.
For Teradata Tools and Utilities 06.02.00 and earlier, the
buffers runtime parameter can be set from 2 to a
maximum of 10. The default value is 2.
Beginning with Teradata Tools and Utilities 06.02.00.01,
the buffers runtime parameter can be set with a lower
limit of 2 and no upper limit. The default value is 3.
The maximum number of request buffers that may be
allocated is BUFFERS * session_count.
Beginning with Teradata Tools and Utilities 06.02.00.01,
request buffers are a global resource, so buffers are
assigned to any session as needed, and then returned to a
free pool. At any point in time, the number of request
buffers assigned to a session can vary from zero to
BUFFERS * session_count.
Prior to Teradata Tools and Utilities 06.02.00.01, a request
buffer was permanently owned by the session to which it
was first assigned, and so could not be used by any other
session. The maximum number of requests buffers that a
session could own was determined by the value of
BUFFERS.
-c charactersetname Defines a character set for the Teradata TPump job.
The character set specification remains in effect for the
entire Teradata TPump job, even if the Teradata Database
server resets, causing the Teradata TPump job to be
restarted.
Note: The character set specification does not remain in
effect if the client system fails, or if the Teradata TPump
job is canceled. In these cases, when the job is
resubmitted, the job must use the same character set
specification that was used on the initial job. If a different
character set specification is used when such a job is
resubmitted, the data loaded by the restarted job will not
appear the same as the data loaded by the initial job.
