Oracle数据库连接字符串简介** Oracle数据库连接字符串是用来建立与Oracle数据库服务器的连接的一种特殊格式的文本字符串。它包含了连接到数据库所需的所有必要信息,例如数据库服务器名称、用户名、密码和连接参数。连接字符串通常以以下格式表示: ``` Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=port))(CONNECT_DATA=(SERVICE_NAME=servicename)));User Id=username;Password=password; ``` 其中,`Data Source`指定了数据库服务器的地址和端口,`User Id`和`Password`指定了连接的用户名和密码,`SERVICE_NAME`指定了要连接的数据库服务。 # 2. 连接字符串参数详解 ### 2.1 基本参数 #### 2.1.1 连接名 * **参数名称:** ConnectString * **参数类型:** 字符串 * **必填:** 是 * **描述:** 唯一标识数据库连接的名称。它通常与 TNS 别名或 EZConnect 字符串相同。 * **示例:** ``` Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=XE))); ``` #### 2.1.2 用户名 * **参数名称:** User ID * **参数类型:** 字符串 * **必填:** 是 * **描述:** 连接数据库的用户名。 * **示例:** ``` User ID=scott; ``` #### 2.1.3 密码 * **参数名称:** Password * **参数类型:** 字符串 * **必填:** 是 * **描述:** 连接数据库的密码。 * **示例:** ``` Password=tiger; ``` ### 2.2 高级参数 #### 2.2.1 连接池 * **参数名称:** Pooling * **参数类型:** 布尔值 * **必填:** 否 * **默认值:** false * **描述:** 指定是否使用连接池。连接池可以提高性能,因为它可以重用现有的数据库连接,而不是每次都创建一个新的连接。 * **示例:** ``` Pooling=true; ``` #### 2.2.2 负载均衡 * **参数名称:** Load Balancing * **参数类型:** 字符串 * **必填:** 否 * **默认值:** off * **描述:** 指定负载均衡策略。负载均衡可以将连接分散到多个数据库服务器,从而提高可扩展性和可用性。 * **示例:** ``` Load Balancing=on; ```
