Teradata TPump also:
• Maintains or drops the restart log table, depending on the success or failure of the job.
• If specified, Teradata TPump returns the optional retcode value to the client operating
system.
See the LOGON command description in Chapter 3 for more information about return codes
and the conditions that maintain or drop the restart log table.
The procedure for aborting a Teradata TPump job depends on whether the utility is running
on a network-attached or a channel-attached client system:
To abort a Teradata TPump job running on a channel-attached client system
✔ Cancel the job from the client system console.
To abort a Teradata TPump job running on a network-attached client system
✔ Press the Control + C key combination three times on the workstation keyboard.
After Terminating a Teradata TPump Job
After terminating a Teradata TPump job:
• Restart the job and allow it to run to completion
• Reinitialize the job and run it to completion
• Abandon the job and clean up the database objects.
For more information on how to perform the above options, see “Restart and Recovery.”.
Restart and Recovery
This section explains Teradata TPump’s handling of restart and recovery operations in the
event of a system failure.
The Teradata TPump facility includes a number of features that enable recovery from client or
Teradata Database failure, with minimal requirements for job resubmission or continuation.
Upon restart or resubmission, Teradata TPump interrogates the restart log table on Teradata
Database and resumes operations from where it had left off.
