如何:使用 Business Connectivity Services 连接到 Oracle 数据库
上次修改时间: 2010年5月26日
适用范围: SharePoint Server 2010
Microsoft Business Connectivity Services (BCS) 可从以下各类数据库连接到外部数据:
Microsoft SQL Server
Oracle
OLE DB
ODBC
如何:基于 SQL Server 表创建外部内容类型这一主题说明使用 Business Connectivity Services 显示来自 SQL Server 数据库的外部数据的基本方式。在使用其他数据库(如 Oracle、OLE DB 和 ODBC)时,必须遵循下列方法之一(因为 Microsoft SharePoint Designer 2010 不支持这些数据库):
从头开始创建 Business Connectivity Services 模型。有关信息,请参阅创作 BDC 模型。有关编写或修改 Oracle 数据库的模型时的注意事项,请参阅下一节。
创建 Web 服务或 .NET 连接程序集,为数据库中公开的外部数据提供接口。有关详细信息,请参阅Creating Web and WCF Services for Business Connectivity Services和如何:创建 .NET 连接程序集。
创建 BDC 模型以连接到 Oracle 数据库
按照创作 BDC 模型中的过程执行操作以从头开始创建模型。
在编写或修改 BDC 模型以连接到 Oracle 时,应记住以下注意事项:
Oracle SQL 语法要求您按以下方式指定查询中的参数:为参数添加冒号 (:) 而非 @ 符号前缀。确保在元数据的 SQL 语句中正确设置它们。
如果 Oracle 连接需要连接字符串中的显式用户 ID 和密码参数,则:
使用 Oracle 凭据在 Secure Store Service 中设置应用程序定义。
使用 RdbCredentials 的 AuthenticationMode。
在将 RdbCredentials 用作验证模式时,无法使用 RdbConnection User ID 和 RdbConnection Password 属性,因为这些值是由 Secure Store Service 提供的。如果指定这些值,则会将其忽略。必须使用安全存储来提供 Oracle 凭据。
必须在服务器场中的所有计算机上安装 Oracle 客户端,并且必须将 TNS net 服务配置为从 SharePoint 连接到 Oracle。这对于服务器上的外部列表、Web 部件和配置文件页是必需的。由于应用程序(如搜索)只在应用程序服务器上运行,因此可以在应用程序服务器上安装 Oracle 客户端。搜索将只从应用程序服务器连接。简而言之,必须在从中连接到 Oracle 的服务器场的计算机上安装 Oracle 客户端。出于同一原因,还必须在富客户端计算机上安装 Oracle 客户端。
以下示例演示如何为使用 Secure Store Service 进行连接的 Oracle 数据库设置 LobSystemInstance 属性。将 YOUR_ORACLE_NET_SERVICE_NAME_HERE 替换为 TNS net 服务名称,并将 SECURESTORE_ORACLE_APP_ID_HERE 替换为在 Secure Store Service 中设置的企业应用程序定义的名称。
