Preface

This manual describes how to use the Oracle8 Server utilities for data transfer, maintenance, and database administration.

Oracle8 Utilities contains information that describes the features and functionality of the Oracle8 and the Oracle8 Enterprise Edition products. Oracle8 and Oracle8 Enterprise Edition have the same basic features. However, several advanced features are available only with the Enterprise Edition, and some of these are optional.

For information about the differences between Oracle8 and the Oracle8 Enterprise Edition and the features and options that are available to you, see Getting to Know Oracle8 and the Oracle8 Enterprise Edition.

## The Oracle Utilities

This manual describes the basic concepts behind each utility and provides examples to show how the utilities are used.

Some of the information this manual provides must be supplemented for the high-security version of the Oracle8 Server, Trusted Oracle. Such information is marked with references to the Trusted Oracle documentation.

## Audience

This manual is 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/Import utilities
- load data into Oracle tables from operating system files using SQL*Loader
- create and maintain user-defined character sets (NLS Utilities) and other Oracle NLS data

To use this manual, you need a working knowledge of SQL and Oracle8 fundamentals, information that is contained in Oracle8 Concepts. In addition, SQL*Loader requires that you know how to use your operating system's file management facilities.

Note: This manual does not contain instructions for installing the utilities, which is operating system-specific. Installation instructions for the utilities can be found in your operating system-specific Oracle8 documentation.

## How Oracle8 Utilities Is Organized

This manual is divided into four parts:

### Part I: Export/Import

Chapter 1, "Export"

This chapter describes how to use Export to write data from an Oracle database into transportable files. It discusses guidelines, export modes, interactive and command-line methods, parameter specifications, and incremental exports. It also provides several examples of Export sessions.

Chapter 2, "Import"

This chapter shows you how to use Import to read data from Export files into an Oracle database. It discusses guidelines, interactive and command-line methods, parameter specifications, and incremental imports. It also provides several examples of Import sessions.

### Part II: SQL*Loader

Chapter 3, "SQL*Loader Concepts"

This chapter introduces SQL*Loader and describes its features. It also introduces data loading concepts. It discusses input to SQL*Loader, database preparation, and output from SQL*Loader.

Chapter 4, "SQL*Loader Case Studies"

This chapter presents case studies that illustrate some of the features of SQL*Loader. It demonstrates the loading of variable-length data, fixed-format records, a free-format file, multiple physical records as one logical record, multiple tables, and direct file loads.

Chapter 5, "SQL*Loader Control File Reference"

This chapter describes the data definition language (DDL) used by SQL*Loader to map data to Oracle format. It discusses creating the control file to hold DDL source, using the LOAD DATA statement, specifying data files, specifying tables and columns, and specifying the location of data.

Chapter 6, "SQL*Loader Command-Line Reference"

This chapter describes the command-line syntax used by SQL*Loader. It discusses the SQLLOAD command, command-line arguments, suppressing SQL*Loader messages, and sizing the bind array.

Chapter 7, "SQL*Loader: Log File Reference"

This chapter describes the information contained in the log file.

Chapter 8, "SQL*Loader: Conventional and Direct Path Loads"

This chapter describes the conventional path load method and the direct path load method- a high performance option that significantly reduces the time required to load large quantities of data.

### Part III: NLS Utilities

Chapter 9, "National Language Support Utilities"

Part III explains how to use the NLS utilities: the NLS Data Installation utility, which helps you convert text-format updates to NLS objects; The NLS Configuration utility, which helps you configure your NLS boot files so that only the NLS objects you want will be loaded; the NLS Calendar utility, which allows you to update existing NLS calendar data with additional ruler eras.

### Part IV: Offline Database Verification Utility

Chapter 10, "Offline Database Verification Utility"

This chapter describes how to use the offline database verification utility.

Appendix A, "SQL*Loader Reserved Words"

This appendix lists the words reserved by the Oracle utilities.

Appendix B, "DB2/DXT User Notes"

This appendix describes differences between the data definition language syntax of SQL*Loader and DB2 Load Utility control files. It discusses SQL*Loader extensions to the DB2 Load Utility, the DB2 RESUME option, options included for compatibility, and SQL*Loader restrictions.

## Conventions Used in This Manual

This manual follows textual and typographic conventions explained in the following sections.

### Text of the Manual

The following conventions are used in the text of this manual:

#####

UPPERCASE Words | Uppercase text is used to call attention to command keywords, object names, parameters, filenames, and so on, for example:
| "If you create a private rollback segment, its name must be included in the ROLLBACK_SEGMENTS parameter in the PARAMETER file."
Italicized Words | Italicized words are used at the first occurrence and definition of a term, as in the following example:
| "A database is a collection of data to be treated as a unit. The general purpose of a database is to store and retrieve related information, as needed."
| Italicized words are used also to indicate emphasis, book titles, and to highlight names of performance statistics.

PL/SQL, SQL, and SQL*Plus commands and statements are displayed in a fixed-width font using the following conventions, separated from normal text as in the following example:

    ALTER TABLESPACE users   ADD DATAFILE 'users2.ora' SIZE 50K;

#####

Punctuation: , ' " | Example statements may include punctuation such as commas or quotation marks. All punctuation given in example statements is required. All statement examples end with a semicolon. Depending on the application in use, a semicolon or other terminator may or may not be required to end a statement.
UPPERCASE Words: INSERT, SIZE | Uppercase words in example statements indicate the keywords in Oracle SQL. However, when you issue statements, keywords are not case-sensitive.
Lowercase Words: emp, users2.ora | Lowercase words in example statements indicate words supplied only for the context of the example. For example, lowercase words may indicate the name of a table, column, or file. Some operating systems are case sensitive, so refer to your installation or user's manual to find whether you must pay attention to case.
