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

808 Using the TPT API 4 Chapter 28TPT API SetupHere are the requirements for using the TPT API in SAS for loading SAS.3 Loading data from SAS to Teradata using the TPT API requires Teradata clientTTU 8.2 or later. Verify that you have applied all of the latest Teradata eFixes.3 This feature is supported only on platforms for which Teradata provides the TPTAPI.3 The native TPT API infrastructure must be present on your system. ContactTeradata if you do not already have it but want to use it with SAS.The SAS configuration document for your system contains information about how toconfigure SAS to work with the TPT API. However, those steps might already havebeen completed as part of the post-installation configuration process for your site.TPT API LIBNAME OptionsThe TPT= LIBNAME option is common to all three supported load methods. If SAScannot use the TPT API, it reverts to using Fastload, MultiLoad, or Multi-Statementinsert, depending on which method of loading was requested without generating anyerrors.TPT API Data Set OptionsThese data set options are common to all three supported load methods:3 SLEEP=3 TENACITY=3 TPT=3 TPT_CHECKPOINT_DATA=3 TPT_DATA_ENCRYPTION=3 TPT_LOG_TABLE=3 TPT_MAX_SESSIONS=3 TPT_MIN_SESSIONS=3 TPT_RESTART=3 TPT_TRACE_LEVEL=3 TPT_TRACE_LEVEL_INF=3 TPT_TRACE_OUTPUT=TPT API FastLoad Supported Features and RestrictionsSAS/ACCESS Interface to Teradata supports the TPT API for FastLoad, also knownas the load driver, SAS/ACCESS works by interfacing with the load driver through theTPT API, which in turn uses the Teradata Fastload protocol for loading data. See yourTeradata documentation for more information about the load driver.This is the default FastLoad method. If SAS cannot find the Teradata modules thatare required for the TPT API or TPT=NO, then SAS/ACCESS uses the old method ofFastload. SAS/ACCESS can restart Fastload from checkpoints when FastLoad uses theTPT API. The SAS/ACCESS FastLoad facility using the TPT API is similar to thenative Teradata FastLoad utility. They share these limitations.3 FastLoad can load only empty tables. It cannot append to a table that alreadycontains data. If you try to use FastLoad when appending to a table that containsrows, the append step fails.
