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

264 BL_LOG= Data Set Option 4 Chapter 11SyntaxBL_LOG=path-and-log-filenameSyntax Descriptionpath-and-log-filenameis a file to which information about the loading process is written.DetailsTo specify this option, you must first set BULKLOAD=YES. See the reference sectionfor your SAS/ACCESS interface for additional details.When the DBMS bulk-load facility is invoked, it creates a log file. The contents of thelog file are DBMS-specific. The BL_ prefix distinguishes this log file from the onecreated by the SAS log. If BL_LOG= is specified with the same path and filename as anexisting log, the new log replaces the existing log.Oracle: When the SQL*Loader is invoked, it creates a log file. This file contains adetailed summary of the load, including a description of any errors. If SQL*Loadercannot create a log file, execution of the bulk load terminates. If a log file does notalready exist, it is created in the current directory or with the default file specifications.If a log file does already exist, the Oracle bulk loader reuses the file, replacing thecontents with information from the new load. On most platforms, the default filenametakes the form BL__.log:tablespecifies the table nameunique-ID specifies a number that is used to prevent collisions in the event oftwo or more simultaneous bulk loads of a particular table. TheSAS/ACCESS engine generates the number.DB2 under UNIX and PC Hosts: If BL_LOG= is not specified, the log file is deletedautomatically after a successful operation. For more information, see the bulk-loadtopic in the DB2 under UNIX and PC Hosts bulk loading section.Teradata: For more information, see the bulk-load topic in the Teradata sectioninterface.See AlsoTo assign this option to a group of relational DBMS tables or views, see the“BL_LOG= LIBNAME Option” on page 100.“BULKLOAD= Data Set Option” on page 290“Bulk Loading for DB2 Under UNIX and PC Hosts” on page 472“Maximizing Teradata Load Performance” on page 804 (Teradata bulk loading)
