This guide includes the conceptual and task-oriented information you need to perform backup, restore, and recovery procedures using the Recovery Manager utility. It assumes that you are familiar with the basic concepts of backup and recovery described in the Oracle8i Backup and Recovery Guide.

The Oracle8i Recovery Manager User's Guide and Reference contains information that describes the features and functionality of the Oracle8i Standard Edition and the Oracle8i Enterprise Edition products. The Standard Edition and Enterprise Edition have the same basic features, but several advanced features are available only with the Enterprise Edition, and some of these are optional. For example, to use Recovery Manager to perform automated tablespace point-in-time recovery, you must have the Enterprise Edition.

Changes to This Book

The following aspects of this manual are new in release 8.1.6:


This guide is for database administrators (DBAs) who administer the backup, restore, and recovery operations of an Oracle database system using the Recovery Manager utility.

Knowledge Assumed of the Reader

Readers of this guide are assumed to be familiar with:


This section explains the conventions used in this manual including the following:


This section explains the conventions used within the text:

UPPERCASE Characters

Uppercase text is used to call attention to tablespace names, initialization parameters, and SQL keywords.

For example, "If you create a private rollback segment, the name must be included in the ROLLBACK_SEGMENTS parameter of the init.ora file. You can view this information by issuing a SHOW PARAMETER statement in SQL*Plus."

Italicized Characters

Italicized words within text are book titles, new vocabulary, emphasized words, or variables in SQL or Recovery Manager syntax.

For example, "An archived redo log is an online redo log that has been copied offline. You must run your database in ARCHIVELOG mode to enable this feature. If you are using Recovery Manager, you can specify an archived redo log in a backup command by using the archivelog like '/oracle/archive/arc_*' sub-clause."

Bold Characters

Bold words within text are Recovery Manager keywords or operating system-specific commands.

For example, "Use the Recovery Manager backup command to back up your database. Alternatively, use the UNIX cp command to copy files."

Monospaced Characters

Filenames and directories appear in a monospaced font. Also, monospaced characters in text preceding a code example indicates a filename or keyword used in the sample code.

For example, "This command backs up the tablespace TBS_1:

run {
     allocate channel c1 type disk;
     backup tablespace tbs_1;

Recovery Manager Syntax Diagrams and Notation

For information about Recovery Manager syntax conventions, see "Conventions Used in this Reference".

Code Examples

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

INSERT INTO emp (empno, ename) VALUES (1000, 'SMITH'); 
run {
     allocate channel ch1 type disk;
     backup database;

When you run RMAN from the command line, the command prompt appears as RMAN>. When you issue commands from the SQL*Plus command line, the prompt appears as SQL>. These prompts are displayed in the code examples only when they are necessary to prevent confusion.

You can execute SQL, SQL*Plus, and RMAN commands in different environments on different platforms. As much as possible, this guide attempts to provide generic documentation, that is, documentation that is not specific to any operating system or interface. Nevertheless, it is sometimes necessary for illustrative purposes to show how the syntax works at the operating system level. In these cases, this book uses examples from a UNIX command-line interface and employs the % symbol to indicate the operating system prompt. For example:

% rman target / rcvcat rman/rman@inst2
RMAN> startup

How to Use This Guide

This manual contains the following basic types of information:

To acquaint yourself with the basic features of RMAN, read Chapter 1, "Recovery Manager Concepts" and then Chapter 2, "Getting Started with Recovery Manager". Refer to the procedural chapters for information about specific tasks. Finally, refer to the reference chapters for clarification about RMAN syntax or the columns in the catalog views.
