Each Teradata PT job automatically creates three associated checkpoint files during job execution and places them in the specified checkpoint directories. These files extend across multiple job steps, if the job has more than one step. They are automatically deleted after a job runs all the way to completion without errors, but if any step fails to finish successfully, the checkpoint files are not deleted and remain in the checkpoint directory.

Default name formulas for the standard job checkpoint files vary by operating system as follows:

On UNIX and Windows platforms:

  • <job identifier>CPD1
  • <job identifier>CPD2
  • <job identifier>LVCP

where <job identifier> is the job name from the tbuild command line, if a jobname was specified, or the userid in the job logon, if a job name was not specified.

On z/OS platforms, the checkpoint datasets have the following DDNAMEs:

  • //CPD1
  • //CPD2
  • //LVCP
