授予 Oracle 权限的脚本

本主题中提供的脚本用于配置使用 Microsoft SQL Server 复制发布数据的 Oracle 数据库。 安装后，该脚本也位于以下目录下：<驱动器>:\\Program Files\Microsoft SQL Server\<实例名>\MSSQL\Install\oracleadmin.sql。 有关配置 Oracle 数据库的详细信息，请参阅配置 Oracle 发布服务器。

注意注意

该脚本包含 GRANT CREATE ANY TRIGGER TO &&AdminLogin; 语句，事务复制所用的触发器需要这个语句。 如果您仅使用快照复制，请将该行从脚本中删除。

若要从 Oracle SQL*Plus 实用工具运行该脚本，则请

  1. 在 SQL Server 分发服务器中，打开一个命令提示符窗口。

  2. 若要使用 SQL*PLUS 连接到 Oracle 数据库并从其默认安装目录执行 oracleadmin.sql 脚本，请键入以下语法：

    sqlplus system/P@$$W0rd@orcl @"c:\Program Files\Microsoft SQL Server\<InstanceName>\MSSQL\Install\oracleadmin.sql"

    在此示例中，使用内置 Oracle 帐户 system 连接到网络名称为“orcl”的 Oracle 数据库。

  3. 在得到提示后，请指定用户名称、用户密码和默认的表空间。

-- 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;
