LOGFILE

Default: export.log

Purpose

Specifies the name, and optionally, a directory, for the log file of the export job.

Syntax and Description

LOGFILE=[directory_object:]file_name

You can specify a database directory_object previously established by the DBA, assuming that you have access to it. This overrides the directory object specified with the DIRECTORY parameter.

The file_name specifies a name for the log file. The default behavior is to create a file named export.log in the directory referenced by the directory object specified in the DIRECTORY parameter.

All messages regarding work in progress, work completed, and errors encountered are written to the log file. (For a real-time status of the job, use the STATUS command in interactive mode.)

A log file is always created for an export job unless the NOLOGFILE parameter is specified. As with the dump file set, the log file is relative to the server and not the client.

An existing file matching the file name will be overwritten.

Restrictions

To perform a Data Pump Export using Oracle Automatic Storage Management (Oracle ASM), you must specify a LOGFILE parameter that includes a directory object that does not include the Oracle ASM + notation. That is, the log file must be written to a disk file, and not written into the Oracle ASM storage. Alternatively, you can specify NOLOGFILE=YES. However, this prevents the writing of the log file.

Example

The following example shows how to specify a log file name if you do not want to use the default:

> expdp hr DIRECTORY=dpump_dir1 DUMPFILE=hr.dmp LOGFILE=hr_export.log

Note:

Data Pump Export writes the log file using the database character set. If your client NLS_LANG environment setting sets up a different client character set from the database character set, then it is possible that table names may be different in the log file than they are when displayed on the client output screen.
