This document describes how to use Oracle Database utilities for data transfer, data maintenance, and database administration.


The utilities described in this book are intended for database administrators (DBAs), application programmers, security administrators, system operators, and other Oracle users who perform the following tasks:

  • Archive data, back up an Oracle database, or move data between Oracle databases using the Export and Import utilities (both the original versions and the Data Pump versions)

  • Load data into Oracle tables from operating system files using SQL*Loader, or from external sources using the external tables feature

  • Perform a physical data structure integrity check on an offline database, using the DBVERIFY utility

  • Maintain the internal database identifier (DBID) and the database name (DBNAME) for an operational database, using the DBNEWID utility

  • Extract and manipulate complete representations of the metadata for database objects, using the Metadata API

  • Query and analyze redo log files (through a SQL interface), using the LogMiner utility

  • Use the Automatic Diagnostic Repository Command Interpreter (ADRCI) utility to manage Oracle Database diagnostic data.

To use this manual, you need a working knowledge of SQL and of Oracle fundamentals. You can find such information in Oracle Database Concepts. In addition, to use SQL*Loader, you must know how to use the file management facilities of your operating system.
