Conventions

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

Conv
entions in Text
Conventions in Code Examples

 
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 r
ecovery catalog and target database do not reside on the same disk.

 
UPPERCASE monospace (fixed-width) font
 
Uppercase monospace typeface indicates elements supplied by the syst
em. 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. 
<
p class="TB">You can back up the database by using the BACKUP command. 
Query the
 TABLE_NAME column in the USER_TABLES data dictionary view. 
Use the
 DBMS_STATS.GENERATE_STATS procedure.

 
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-sup
plied 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 open SQL*Plus. 

The password is specified in the orapwd file. 
Back up the datafiles and control files in the /disk1/oracle/dbs directory. 
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. 
<
p class="TB">The JRepUtil class implements these methods.

 
lowercase italic monospace (fixed-width) font
 
Lowercase italic monospace font represents placeholders or variables.

 
You can specify the parallel_clause. 
Run Uold_release.SQL where old_release
 refers to the release you installed prior to upgrading.
 
Conventions in Code Examples
 
Code examples i
llustrate 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';

UPPERCASE



Upperc
ase 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 ca

SELECT last_name,
 employee_id FROM employees;
SELECT * FROM USER_TABLES;
DROP TABLE hr.employees;




lowercase





Lowercase typeface indicates programmatic elements that you supply. F
or 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.
