Text of the Manual

The following sections describe the conventions used in the text of this manual.

UPPERCASE Characters

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, the name must be included in the ROLLBACK_SEGMENTS parameter of the parameter file."

Italicized Characters

Italicized words within text indicate the definition of a word, book titles, or emphasized words.

An example of a definition is the following: "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."

An example of a reference to another book is the following: "For more information, see Oracle7 Server Tuning."

An example of an emphasized word is the following: "You must back up your database regularly."

Code Examples

SQL, Server Manager line mode, and SQL*Plus commands/statements appear separated from the text of paragraphs in a monospaced font. For example:

INSERT INTO emp (empno, ename) VALUES (1000, 'SMITH');

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

Example statements may include punctuation, such as commas or quotation marks. All punctuation in example statements is required. All example statements terminate with a semicolon (;). Depending on the application, a semicolon or other terminator may or may not be required to end a statement.

Uppercase words in example statements indicate the keywords within Oracle SQL. When issuing statements, however, keywords are not case sensitive.

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.
