Script para conceder permisos en Oracle
El script que se proporciona en este tema se utiliza durante la configuración de una base de datos de Oracle que publicará datos utilizando la replicación de Microsoft SQL Server. Este script también está disponible en el directorio siguiente después de la instalación: <unidadDeDisco>: \\Archivos de programa\Microsoft SQL Server \<nombreDeInstancia>\MSSQL\Install\oracleadmin.sql. Para obtener más información acerca de la configuración de la base de datos de Oracle, vea Configurar un publicador de Oracle.
Nota
Este script incluye la instrucción GRANT CREATE ANY TRIGGER TO &&AdminLogin;, que es necesaria para los desencadenadores que utiliza la replicación transaccional. Si sólo va a utilizar replicación de instantáneas, quite esta línea de la línea de comandos.
Para ejecutar el script desde la utilidad SQL*Plus de Oracle
En el distribuidor de SQL Server, abra una ventana del símbolo del sistema.
Para usar SQL*PLUS para conectarse a la base de datos de Oracle y ejecutar el script oracleadmin.sql desde su directorio de instalación predeterminado, escriba la sintaxis siguiente:
sqlplus system/P@$$W0rd@orcl @"c:\Program Files\Microsoft SQL Server\<InstanceName>\MSSQL\Install\oracleadmin.sql"En este ejemplo, se usa la cuenta integrada de Oracle system para conectarse a una base de datos de Oracle con el nombre de red "orcl".
Cuando se le solicite, especifique el nombre de usuario, la contraseña de usuario y el espacio de tabla predeterminado.

-- File:
-- oracleadmin.sql
--
-- Purpose:
-- PL/SQL script to create a database user with the required
-- permissions to administer SQL Server publishing for an Oracle
-- database.
--
-- &&ReplLogin == Replication user login
-- &&ReplPassword == Replication user password
-- &&DefaultTablespace == Tablespace that will serve as the default
-- tablespace for the replication user.
-- The replication user will be authorized to allocate UNLIMITED space
-- on the default tablespace, which must already exist.
--
-- Notes:
--
-- This script must be run from an Oracle login having the
-- authorization to create a new user and grant unlimited tablespace on
-- any existing tablespace. The login must also be able to grant to the
-- newly created login the following authorizations:
--
-- create public synonym
-- drop public synonym
-- create sequence
-- create procedure
-- create session
-- create table
-- create view
--
-- Additionally, the following properties are also required for
-- transactional publications.
--
-- create any trigger
--
-- All of the privileges may be granted through a role, with the
-- exception of create table, create view, and create any trigger.
-- These must be granted explicitly to the replication user login.
-- In the script, all grants are granted explicitly to the replication
-- user.
--
-- In addition to these general grants, a table owner must explicitly
-- grant select authorization to the replication user on a table before
-- the table can be published.

CREATE USER &&ReplLogin IDENTIFIED BY &&ReplPassword DEFAULT TABLESPACE &&DefaultTablespace QUOTA UNLIMITED ON &&DefaultTablespace;
-- It is recommended that only the required grants be granted to this
-- user.
--
-- The following 5 privileges are granted explicitly, but could be
-- granted through a role.
GRANT CREATE PUBLIC SYNONYM TO &&ReplLogin;
GRANT DROP PUBLIC SYNONYM TO &&ReplLogin;
GRANT CREATE SEQUENCE TO &&ReplLogin;
GRANT CREATE PROCEDURE TO &&ReplLogin;
GRANT CREATE SESSION TO &&ReplLogin;
-- The following privileges must be granted explicitly to the
-- replication user.
GRANT CREATE TABLE TO &&ReplLogin;
GRANT CREATE VIEW TO &&ReplLogin;
-- The replication user login needs to be able to create a tracking
-- trigger on any table that is to be published in a transactional
-- publication. The CREATE ANY privilege is used to obtain the
-- authorization to create these triggers. To replicate a table, the
-- table owner must additionally explicitly grant select authorization
-- on the table to the replication user.
--
-- NOTE: CREATE ANY TRIGGER is not required for snapshot publications.
GRANT CREATE ANY TRIGGER TO &&ReplLogin;
