To use this document, you need to be familiar with relational database concepts, basic Oracle server concepts, and the operating system environment under which you are running Oracle.
Our goal is to make Oracle products, services, and supporting documentation accessible to all users, including users that are disabled. 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. Accessibility 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.

Accessibility of Code Examples in Documentation
Screen readers 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, some screen readers may not always read a line of text that consists solely of a bracket or brace.
Accessibility of Links to External Web Sites in Documentation
This documentation may contain links to Web sites of other companies or organizations that Oracle does not own or control. Oracle neither evaluates nor makes any representations regarding the accessibility of these Web sites.
Deaf/Hard of Hearing Access to Oracle Support Services
To reach Oracle Support Services, use a telecommunications relay service (TRS) to call Oracle Support at 1.800.223.1711. An Oracle Support Services engineer will handle technical issues and provide customer support according to the Oracle service request process.

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 | Bold typeface indicates terms that are defined in the text or terms that appear in a glossary, or both. | When you specify this clause, you create an index-organized table. |
Italics | Italic typeface indicates book titles or emphasis. | Oracle Database Concepts
Ensure that the recovery catalog and target database do not reside on the same disk. |
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 by using the Query the Use the |
lowercase monospace (fixed-width) font |
Lowercase monospace typeface indicates executables, filenames, directory names, 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.
Note: Some programmatic elements use a mixture of UPPERCASE and lowercase. Enter these elements as shown. |
Enter sqlplus to start SQL*Plus.
The password is specified in the Back up the datafiles and control files in the The Set the Connect as The |
lowercase italic monospace (fixed-width) font |
Lowercase italic monospace font represents placeholders or variables. | You can specify the parallel_clause .
Run |
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. |
{ENABLE | DISABLE} |
| |
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. |
{ENABLE | DISABLE} [COMPRESS | NOCOMPRESS] |
... |
Horizontal ellipsis points indicate either:
|
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. |
SQL> SELECT NAME FROM V$DATAFILE; NAME ------------------------------------ /fsl/dbs/tbs_01.dbf /fs1/dbs/tbs_02.dbf . . . /fsl/dbs/tbs_09.dbf 9 rows selected. |
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; |
Italics
|
Italicized text indicates placeholders or variables for which you must supply particular values. |
CONNECT SYSTEM/system_password DB_NAME = database_name |
UPPERCASE |
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; SELECT * FROM USER_TABLES; DROP TABLE hr.employees; |
lowercase |
Lowercase typeface indicates programmatic elements that you supply. For example, lowercase indicates names of tables, columns, or files.
Note: Some programmatic elements use a mixture of UPPERCASE and lowercase. Enter these elements as shown. |
SELECT last_name, employee_id FROM employees; sqlplus hr/hr CREATE USER mjones IDENTIFIED BY ty3MU9; |
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. | To start the Database Configuration Assistant, choose Start > Programs > Oracle - HOME_NAME > Configuration and Migration Tools > Database Configuration Assistant. |
File and directory names | File and directory names are not case sensitive. The following special characters are not allowed: left angle bracket (<), right angle bracket (>), colon (:), double quotation marks ("), slash (/), pipe (|), and dash (-). The special character backslash (\) is treated as an element separator, even when it appears in quotes. If the file name begins with \\, then Windows assumes it uses the Universal Naming Convention. |
c:\winnt"\"system32 is the same as C:\WINNT\SYSTEM32 |
C:\> |
Represents the Windows command prompt of the current hard disk drive. The escape character in a command prompt is the caret (^). Your prompt reflects the subdirectory in which you are working. Referred to as the command prompt in this manual. |
C:\oracle\oradata> |
Special characters | The backslash (\) special character is sometimes required as an escape character for the double quotation mark (") special character at the Windows command prompt. Parentheses and the single quotation mark (') do not require an escape character. Refer to 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)
|
HOME_NAME
|
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. |
C:\> net start OracleHOME_NAMETNSListener
|
ORACLE_HOME and ORACLE_BASE |
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 used one of the following names:
This release complies with Optimal Flexible Architecture (OFA) guidelines. All subdirectories are not under a top level All directory path examples in this guide follow OFA conventions. Refer to Oracle Database Platform Guide for Windows for additional information about OFA compliances and for information about installing Oracle products in non-OFA compliant directories. |
Go to the ORACLE_BASE \ ORACLE_HOME \rdbms\admin directory. |
