Teradata Support environment variables in DataStage

The following environment variables are concerned with DataStage® interaction with Teradata databases.

APT_TERA_64K_BUFFERS environment variable in DataStage

Set the APT_TERA_64K_BUFFERS environment variable so that the terawrite operator writes to buffers that are 64 KB rather than 32 KB.

APT_TERA_NO_ERR_CLEANUP environment variable in DataStage

Set the APT_TERA_NO_ERR_CLEANUP environment variable to prevent the removal of error tables and the partially written target table of an incomplete terawrite operation.

Set this variable for diagnostic purposes only. In some cases, setting this variable forces completion of an unsuccessful write operation.
