It would most likely be oneof the first statements in your SAS code:option dbsliceparm=(threaded_apps,3);This code uses DBSLICEPARM= as a LIBNAME option to turn on threaded reads forread-only table references that use this particular libref:libname dblib oracle user=scott password=tiger dbsliceparm=ALL;Here is how to use DBSLICEPARM= as a table level option to turn on threadedreads for this particular table, requesting up to four connections:proc reg SIMPLE;data=dblib.customers (dbsliceparm=(all,4));var age weight;where years_active>1;run;See Also“DBSLICE= Data Set Option” on page 316“DBSLICEPARM= LIBNAME Option” on page 137DBTYPE= Data Set OptionSpecifies a data type to use instead of the default DBMS data type when SAS creates a DBMS table.Default value: DBMS-specificValid in: DATA and PROC steps (when accessing DBMS data using SAS/ACCESSsoftware)DBMS support: Aster nCluster, DB2 under UNIX and PC Hosts, DB2 under z/OS,Greenplum, HP Neoview, Informix, Microsoft SQL Server, MySQL, Netezza, ODBC,OLE DB, Oracle, Sybase, Sybase IQ, Teradata
