Oracle Security

Conventions Used in This Book

The following conventions are used in this book:

Note

Indicates a tip, suggestion, or general note. For example, we’ll tell you if you need to use a particular Oracle version or if an operation requires certain privileges.

Warning

Indicates a warning or caution. For example, we’ll tell you if Oracle does not behave as you’d expect or if a particular operation has a negative impact on performance.

Italic

Used for script names, filenames, and directory names, and Oracle usernames.

Constant width

Used for code examples.

Constant width italic

In some code examples, indicates an element (e.g., a filename) that you supply.

UPPERCASE

In code examples, generally indicates Oracle keywords.

lowercase

In code examples, generally indicates user-defined items such as variables, parameters, etc.

punctuation

In code examples, enter exactly as shown.

/* and */

In code examples, these characters delimit a comment, which can extend from one line to another.

[ ]

In syntax descriptions, square brackets enclose optional items.

Note

This book contains many examples of SQL scripts that we hope will help improve your database security. Wherever possible in this code, we’ve followed the conventions listed above. Using these conventions helps make the usage clear and also ensures consistency both within this book and across the O’Reilly Oracle line. However, we don’t endorse this style for everyone and recognize that in the real world, DBAs and developers write code in a far less structured and consistent style. Where we obtained working scripts from other sources, we have preserved the original formatting to avoid any possible confusion.
