DBA_EXP_FILES

DBA_EXP_FILES describes export files.

Column	Datatype	NULL	Description
EXP_VERSION	NUMBER(3)	NOT NULL	Version number of the export session
EXP_TYPE	VARCHAR2(11)		Type of export file: complete, cumulative, or incremental
FILE_NAME	VARCHAR2(100)	NOT NULL	Name of the export file
USER_NAME	VARCHAR2(30)	NOT NULL	Name of user who executed export
TIMESTAMP	DATE	NOT NULL	Timestamp of the export session

Note:

1. The DBA_EXP views are only used with incremental exports.

To use the DBA_EXP views to track exports, use the incremental option. Use SYS.INCEXP, SYS.INCFIL, and SYS.INCVID tables to get information regarding table, user, and full exports.

If you are doing an incremental export, and the DBA_EXP views are empty, ensure that the Export parameter RECORD has been set to Y. RECORD controls whether or not entries are made to these tables during incremental exports. The default value for RECORD is Y, but if it has been changed to N you could see this problem on an incremental export.
