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

Data Set Options for Relational Databases 4 BULKEXTRACT= Data Set Option 289DetailsBUFFERS= specifies the number of data buffers to use for transferring data from SASto Teradata. When you use the MULTILOAD= data set option, data is transferred fromSAS to Teradata using shared memory segments. The default shared memory buffersize is 64K. The default number of shared memory buffers used for the transfer is 2.Use BUFFERS= to vary the number of buffers for data transfer from 1 to 8. Use theMBUFSIZE= data set option to vary the size of the shared memory buffers from thesize of each data row up to 1MB.See AlsoFor more information about specifying the size of shared memory buffers, see the“MBUFSIZE= Data Set Option” on page 335.“MULTILOAD= Data Set Option” on page 342BULK_BUFFER= Data Set OptionSpecifies the number of bulk rows that the SAS/ACCESS engine can buffer for output.Default value: 100Valid in: DATA and PROC steps (when accessing DBMS data using SAS/ACCESSsoftware)DBMS support: SybaseSyntaxBULK_BUFFER=numeric-valueSyntax Descriptionnumeric-valueis the maximum number of rows that are allowed. This value depends on the amountof memory that is available to your system.DetailsThis option improves performance by specifying the number of rows that can be held inmemory for efficient retrieval from the DBMS. A higher number signifies that morerows can be held in memory and accessed quickly during output operations.BULKEXTRACT= Data Set OptionRapidly retrieves (fetches) large number of rows from a data set.Default value: NO
