Oracle争:使用 Business Connectivity Services 连接到 Oracle 数据库

Microsoft Business Connectivity Services (BCS)
可由以下各项数据库连接至表面数据:

  • Microsoft SQL Server

  • Oracle

  • OLE DB

  • ODBC

怎样:基于 SQL Server
表创建外部内容类型立无异主题说明下
Business Connectivity Services 显示来自 SQL Server
数据库的表面数据的主导方式。在动用另外数据库(如 Oracle、OLE DB 和
ODBC)时,必须依下列方法有(因为 Microsoft SharePoint Designer 2010
不支持这些数据库):

  1. 从头开始创建 Business Connectivity Services
    模型。有关信息,请参见创作 BDC
    模型。有关编写或修改
    Oracle 数据库的模子时之注意事项,请参见下同样节。

  2. 创造 Web 服务或者 .NET
    连接程序集,为数据库被公开的外表数据提供接口。有关详细信息,请参见Creating
    Web and WCF Services for Business Connectivity Services和怎么:创建
    .NET
    连接程序集。

创办 BDC 模型以连续至
Oracle 数据库


按照创作 BDC
模型受之历程执行操作为从头开始创建模型。

在编排或修改 BDC 模型以连续至 Oracle 时,应切记以下注意事项:

  • Oracle SQL 语法要求您照以下措施指定询问中之参数:为参数上加冒号 (:)
    而不 @ 符号前缀。确保以首数据的 SQL 语句被科学安装它们。

  • 要 Oracle 连接要连续字符串中的显式用户 ID 和密码参数,则:

    1. 使 Oracle 凭据在 Secure Store Service 中装置应用程序定义。

    2. 使用 RdbCredentials 的 AuthenticationMode。

    3. 于以 RdbCredentials 用作验证模式时,无法利用 RdbConnection User
      ID 和 RdbConnection Password 属性,因为这些价值是由 Secure Store
      Service
      提供的。如果指定这些价值,则会用那忽视。必须采用安全存储来供
      Oracle 凭据。

  • 必须于劳务器场中之兼具电脑达安装 Oracle 客户端,并且要用 TNS net
    服务配置为从 SharePoint 连接到 Oracle。这对服务器上的标列表、Web
    部件与安排文件页是必要的。由于应用程序(如搜寻)只于应用程序服务器上运行,因此可以应用程序服务器上安装
    Oracle
    客户端。搜索用只是从应用程序服务器连接。简而言之,必须在居中连接到
    Oracle 的服务器场的微处理器及安 Oracle
    客户端。出于同样案由,还须在富客户端计算机上设置 Oracle 客户端。

以下示例演示如何为使 Secure Store Service 进行连续的 Oracle 数据库设置
LobSystemInstance 属性。将 YOUR_ORACLE_NET_SERVICE_NAME_HERE 替换为
TNS net 服务号,并将 SECURESTORE_ORACLE_APP_ID_HERE 替换为当
Secure Store Service 中安的企业应用程序定义的称谓。
