Script para conceder permisos en Oracle

Se aplica a: SQL Server

El script que se proporciona en este tema se usa durante la configuración de una base de datos de Oracle que va a publicar datos mediante la replicación de Microsoft SQL Server. Este script también está disponible en el directorio siguiente después de la instalación de: <unidad>:\\Archivos de programa\Microsoft SQL Server\<NombreDeInstancia>\MSSQL\Install\oracleadmin.sql. Para más información sobre 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 solo va a utilizar replicación de instantáneas, quite del script esta línea de la línea de comandos.

Para ejecutar el script desde la utilidad SQL*Plus de Oracle

  1. En el distribuidor de SQL Server, abra una ventana del símbolo del sistema.

  2. 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".

  3. 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.  
--

-- 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;

-- 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;
