LOGFILE

Default: import.log

Purpose

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

Syntax and Description

LOGFILE=[directory_object:]file_name

If you specify a directory_object, then it must be one that was previously established by the DBA and that you have access to. This overrides the directory object specified with the DIRECTORY parameter. The default behavior is to create import.log in the directory referenced by the directory object specified in the DIRECTORY parameter.

If the file_name you specify already exists, then it will be overwritten.

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 unless the NOLOGFILE parameter is specified. As with the dump file set, the log file is relative to the server and not the client.

Note:

Data Pump Import writes the log file using the database character set. If your client NLS_LANG environment 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.

Restrictions

To perform a Data Pump Import 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 is an example of using the LOGFILE parameter. You can create the expfull.dmp dump file used in this example by running the example provided for the Export FULL parameter. See "FULL".

> impdp hr SCHEMAS=HR DIRECTORY=dpump_dir2 LOGFILE=imp.log
 DUMPFILE=dpump_dir1:expfull.dmp

Because no directory object is specified on the LOGFILE parameter, the log file is written to the directory object specified on the DIRECTORY parameter.
