Default: The name of the control file, with an extension of .log.
Purpose
The LOG parameter specifies a directory path, or file name, or both for the log file that SQL*Loader uses to store logging information about the loading process.
Syntax and Description
LOG=[[directory/][log_file_name]]
If you specify the LOG parameter, then you must supply a directory name, or a file name, or both.
If no directory name is specified, it defaults to the current directory.
If a directory name is specified without a file name, then the default log file name is used.
Example
The following example creates a log file named emp1.log in the current directory. The extension .log is used even though it is not specified, because it is the default.
LOG=emp1
