The twbkill command terminates all tasks running as part of an application.
When you start Teradata PT using the tbuild command, Teradata PT automatically starts tasks that run in the background. Using the twbkill command with the name of the job terminates all tasks running as part of the application.
On UNIX systems, the twbkill user must either be superuser or have the same user ID as the target Teradata PT job. This command is not available on z/OS systems.
