This preface contains these topics:


This guide is necessary for anyone installing, configuring, or administering Oracle9i Enterprise Edition, Oracle9i Standard Edition or Oracle9i Personal Edition.


This guide describes only the features of Oracle9i Enterprise Edition and Oracle9i software that apply to the Windows NT, Windows 95, Windows 98, and Windows 2000 operating systems. For information about these products that is applicable to all operating systems, see the other documentation included in your package. Instructions for installing the documentation library and viewing its contents are in three README files at the root level of the documentation CD-ROMs:

This section describes the conventions used in the text and code examples of this documentation set. It describes:

Conventions in Text

We use various conventions in text to help you more quickly identify special terms. The following table describes those conventions and provides examples of their use.

Convention  Meaning  Example 


Bold typeface indicates terms that are defined in the text or terms that appear in a glossary, or both. 

The C datatypes such as ub4, sword, or OCINumber are valid.

When you specify this clause, you create an index-organized table.  


Italic typeface indicates book titles, emphasis, syntax clauses, or placeholders. 

Oracle9i Database Concepts

You can specify the parallel_clause.

Run Uold_release.SQL where old_release refers to the release you installed prior to upgrading. 

UPPERCASE monospace (fixed-width font) 

Uppercase monospace typeface indicates elements supplied by the system. Such elements include parameters, privileges, datatypes, RMAN keywords, SQL keywords, SQL*Plus or utility commands, packages and methods, as well as system-supplied column names, database objects and structures, usernames, and roles. 

You can specify this clause only for a NUMBER column.

You can back up the database using the BACKUP command.

Query the TABLE_NAME column in the USER_TABLES data dictionary view.

Specify the ROLLBACK_SEGMENTS parameter.


lowercase monospace (fixed-width font) 

Lowercase monospace typeface indicates executables and sample user-supplied elements. Such elements include computer and database names, net service names, and connect identifiers, as well as user-supplied database objects and structures, column names, packages and classes, usernames and roles, program units, and parameter values. 

Enter sqlplus to open SQL*Plus.

The department_id, department_name, and location_id columns are in the hr.departments table.

Set the QUERY_REWRITE_ENABLED initialization parameter to true.

Connect as oe user. 

Conventions in Code Examples

Code examples illustrate SQL, PL/SQL, SQL*Plus, or other command-line statements. They are displayed in a monospace (fixed-width) font and separated from normal text as shown in this example:

SELECT username FROM dba_users WHERE username = 'MIGRATE';

The following table describes typographic conventions used in code examples and provides examples of their use.

Convention  Meaning  Example 

[ ] 

Brackets enclose one or more optional items. Do not enter the brackets. 

DECIMAL (digits [ , precision ]) 

{ } 

Braces enclose two or more items, one of which is required. Do not enter the braces. 


A vertical bar represents a choice of two or more options within brackets or braces. Enter one of the options. Do not enter the vertical bar. 




Horizontal ellipsis points indicate either:

  • That we have omitted parts of the code that are not directly related to the example

  • That you can repeat a portion of the code


CREATE TABLE ... AS subquery;

SELECT col1, col2,..., coln FROM employees; 



Vertical ellipsis points indicate that we have omitted several lines of code not directly related to the example. 


Other notation 

You must enter symbols other than brackets, braces, vertical bars, and ellipsis points as shown. 

acctbal NUMBER(11,2);

acct CONSTANT NUMBER(4) := 3; 


Italicized text indicates variables for which you must supply particular values. 

CONNECT SYSTEM/system_password 


Uppercase typeface indicates elements supplied by the system. We show these terms in uppercase in order to distinguish them from terms you define. Unless terms appear in brackets, enter them in the order and with the spelling shown. However, because these terms are not case sensitive, you can enter them in lowercase. 

SELECT last_name, employee_id FROM employees;


DROP TABLE hr.employees; 


Lowercase typeface indicates programmatic elements that you supply. For example, lowercase indicates names of tables, columns, or files. 

SELECT last_name, employee_id FROM employees;

sqlplus hr/hr 

Conventions for Windows Operating Systems

The following table describes conventions for Windows operating systems and provides examples of their use.

Convention  Meaning  Example 

Choose Start > 

How to start a program. For example, to start Oracle Database Configuration Assistant, you must click the Start button on the taskbar and then choose Programs > Oracle - HOME_NAME > Database Administration > Database Configuration Assistant.  

Choose Start > Programs > Oracle - HOME_NAME > Database Administration > Database Configuration Assistant 

File and Directory Names 

File/directory names are not case sensitive. The special characters <, >, :, ", /, |, and - are not allowed. The special character \ is treated as an element separator, even when it appears in quotes. If the file name begins with \\, Windows assumes it uses the Universal Naming Convention. 

c:\winnt"\"system32 is the same as C:\WINNT\SYSTEM32 


Represents the Windows command prompt of the current hard disk drive. The escape character in a command prompt is "^". Your prompt reflects the subdirectory in which you are working. Referred to as the command prompt in this manual. 



The backslash special character (\) is sometimes required as an escape character for the double quote (") special character at the Windows command prompt. Parentheses and the single quote special character (') do not require an escape character. See your Windows operating system documentation for more information on escape and special characters. 

C:\>exp scott/tiger TABLES=emp QUERY=\"WHERE job='SALESMAN' and sal<1600\"

C:\>imp SYSTEM/password FROMUSER=scott TABLES=(emp, dept) 


Represents the Oracle home name.

The home name can be up to 16 alphanumeric characters. The only special character allowed in the home name is the underscore.  



In releases prior to Oracle8i release 8.1.3, when you installed Oracle components, all subdirectories were located under a top level ORACLE_HOME directory that by default was:

  • C:\orant for Windows NT

  • C:\orawin95 for Windows 95

  • C:\orawin98 for Windows 98

or whatever you called your Oracle home.

This release complies with Optimal Flexible Architecture (OFA) guidelines. All subdirectories are not under a top level ORACLE_HOME directory. There is a top level directory called ORACLE_BASE that by default is C:\oracle. If you install Oracle9i Release 1 (9.0.1) on a computer with no other Oracle software installed, the default setting for the first Oracle home directory is C:\oracle\ora90. The Oracle home directory is located directly under ORACLE_BASE.

All directory path examples in this guide follow OFA conventions.

See Oracle9i Database Getting Started for Windows for additional information on OFA compliances and for information on installing Oracle products in non-OFA compliant directories. 

Go to the ORACLE_BASE\ORACLE_HOME\rdbms\admin directory.


Documentation Accessibility

Oracle's goal is to make our products, services, and supporting documentation accessible to the disabled community with good usability. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.

JAWS, a Windows screen reader, may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, JAWS may not always read a line of text that consists solely of a bracket or brace.
