SAS/ACCESS 9.2 for Relational Databases: Reference, Fourth Edition

SAS/ACCESS Interface to Teradata 4 Using the TPT API 8093 Data errors are logged in Teradata tables. Error recovery can be difficult if you donot TPT_CHECKPOINT_DATA= to enable restart from the last checkpoint. Tofind the error that corresponds to the code that is stored in the error table, seeyour Teradata documentation. You can restart a failed job for the last checkpointby following the instructions in the SAS error log.3 FastLoad does not load duplicate rows (those where all corresponding fieldscontain identical data) into a Teradata table. If your SAS data set containsduplicate rows, you can use other load methods.Starting FastLoad with the TPT APISee the SAS configuration document for instructions on setting up the environmentso that SAS can find the TPT API modules.You can use one of these options to start FastLoad in theSAS/ACCESS interfaceusing the TPT API:3 the TPT=YES data set option in a processing step that populates an emptyTeradata table3 the TPT=YES LIBNAME option on the destination libref (the Teradata DBMSlibrary where one or more tables are to be created and loaded)FastLoad with TPT API Data Set OptionsThese data set options are specific to FastLoad using the TPT API:3 TPT_BUFFER_SIZE=3 TPT_ERROR_TABLE_1=3 TPT_ERROR_TABLE_2=TPT API MultiLoad Supported Features and RestrictionsSAS/ACCESS Interface to Teradata supports the TPT API for MultiLoad, also knownas the update driver. SAS/ACCESS works by interfacing with the update driverthrough the TPT API. This API then uses the Teradata Multiload protocol for loadingdata. See your Teradata documentation for more information about the update driver.This is the default MultiLoad method. If SAS cannot find the Teradata modules thatare required for the TPT API or TPT=NO, then SAS/ACCESS uses the old method ofMultiLoad. SAS/ACCESS can restart Multiload from checkpoints when MultiLoad usesthe TPT API.The SAS/ACCESS MultiLoad facility loads both empty and existing Teradata tables.SAS/ACCESS supports only insert operations and loading only one target table at time.The SAS/ACCESS MultLoad facility using the TPT API is similar to the nativeTeradata MultiLoad utility. A common limitation that they share is that you must dropthese items on target tables before the load:3 unique secondary indexes3 foreign key references3 join indexesErrors are logged to Teradata tables. Error recovery can be difficult if you do not setTPT_CHECKPOINT_DATA= to enable restart from the last checkpoint. To find theerror that corresponds to the code that is stored in the error table, see your Teradatadocumentation. You can restart a failed job for the last checkpoint by following theinstructions in the SAS error log.
