APT_BUFFERING_POLICY
APT_BUFFERING_POLICY controls the buffering policy for all virtual data sets in all steps.
This environment variable is available in the InfoSphere® DataStage® Administrator, under the Parallel category. The variable has the following settings:
- AUTOMATIC_BUFFERING (default). Buffer a data set only if necessary to prevent a data flow deadlock.
- FORCE_BUFFERING. Unconditionally buffer all virtual data sets. Note that this can slow down processing considerably.
- NO_BUFFERING. Do not buffer data sets. This setting can cause data flow deadlock if used inappropriately.
