APT_CHECKPOINT_PERSISTENT environment variable in DataStage

Set the APT_CHECKPOINT_PERSISTENT environment variable to persist checkpoints between failed job runs.

Specifies if you want to allow checkpoints to be persisted for different jobs that are run. If a job that has a checkpoint enabled fails, then you can manually restart the job if there is are existing checkpoint files which are complete. The job will start from the checkpoints, instead of starting from the beginning. Define this variable with a path to a file name to save the checkpoint data when a job fails and cannot automatically be restarted. The job can be manually rerun with this variable set to the same file to start from any checkpoints that are complete.
