Audience

Oracle Database Advanced Replication Manageme nt API Reference is intended for database administrators and application developers who develop and maintain replication environ ments. These administrators and application developers perform one or more of the following tasks:

Configure replication sites
Create master g roups
Create deployment templates
Create materialized view groups
Configure conflict resolution
Manage replication environments
U se the replication management API
Monitor replication environments using data d ictionary views
Plan and configure security options

To use this document, you need to be familiar with relational database concepts, distributed database administrat ion, PL/SQL (if using procedural replication), and the operating system under which you run an Advanced Replication environment.

Organization

This document contains:

Part I, "Configuring Your Replication Environment"

Includes instr uctions on using the replication management API to set up both multimaster replication and materialized view replication. This part a lso contains instructions for configuring conflict resolution methods and instructions for managing your replication environment usin g the replication management API.

Chapter 1, "Overview of Replication"

Provides an overview of the process for building a replication environment with the replication management API. This chapter a lso contains some prerequisites for building a replication environment.

Chapter 2, "Create Replication Site"

Describes in detail the process of setting up both a master and materialized view site. Co nsult this chapter when building a new replication environment and when adding either a new master or materialized view site to an es tablished replication environment.

Chapter 3, "Create a Master Group"

Conventions

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 y ou more quickly identify special terms. The following table describes those conventions and provides examples of their use.

Convention	Meaning	Example
Bold	< p class="TB">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 t able.
Italics	Italic typeface indicates book t itles 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 str uctures, usernames, and roles.	You can specify this clause only fo r a `NUMBER` column. You can back up the database by using the `BACKUP` command. Query the `TABLE_NAME` column in the `USER_TABLES` data dicti onary view. Use the `DBMS_STATS`.`GENERATE_STATS` procedure.
`lowercase monospa ce (fixed-width) font`	Lowercase monospace typeface indicate s 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.	< a name="970265"> 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_n ame`, and `location_id` columns are in the `hr.departments` table. Set the `QUERY_REWRITE_ENABLED` initialization parameter to `true.` C onnect as `oe` user. The `JRepUtil` class implements these methods.
`lowerc ase italic monospace (fixed-width) font`	Lowercase ital ic monospace font represents placeholders or variables.	You can sp ecify the `parallel_clause`. Run `U``old_release``.SQL where old_release refers to the release you installed prior to upgrading.`

Conventions in Code Examples

Code examples illustrate SQL, PL/SQL, SQL*Plus, or other command-line statements. They ar e 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.

< tr class="Informal" align="left" valign="top">

Convention	Meaning	Example
[ ]	Brackets enclose one or more optional items. Do not enter the brackets.	DECIMAL (digits [ , precision ])
{ }	Braces enclose two or more it ems, 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: That we have omitted parts of the code that are not directly related to the example That you can repeat a portion of the code	CREATE TABLE ... AS subquery; SELECT col1, col2, ... , coln FROM employees;
. . < /a> .	Vertical ellipsis points indicate that we have omitted se veral 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 . . . < a name="970338">/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 va riables for which you must supply particular values.	CONNECT SYS TEM/system_password DB_NAME = database_name
UPPERCASE	Uppercase typeface indicates elements supplied by the system. We show these ter ms 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_TAB LES; DROP TABLE hr.employees;
lowercase	Lowercas e 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 low ercase. Enter these elements as shown.	SELECT last_name, employe e_id FROM employees; sqlplus hr/hr CREATE USER mjones IDENTIFIED BY ty3MU9;
