将 jmeter 与 sybase (15.7) 与 jtds-1.3.1 连接时出错

Question

我正在尝试将 Apache Jmeter (5.2.1) 与 Sybase 15.7 数据库连接，我用来建立此连接的驱动程序是位于 (c:/jmeter/lib/jtds) 的 jtds-1.3.1.jar -1.3. 1.jar) 并且在执行测试计划时出现以下错误：

• DATA BASE URL: jdbc: jtds: sybase: //XX.XXX: XXX.XX: XXXX / 门户
• JDBC 驱动类：net.sourceforge.jtds.jdbc.Driver
• 我排除这是一个通信问题，因为在同一台服务器上我配置了数据源，我可以从应用程序对 Sybase DB 进行查询

Answer 1

您好像忘记添加Validation Query

(String) 在将连接返回给调用者之前，将用于验证来自该池的连接的 SQL 查询。如果指定，此查询不必返回任何数据，它只是不能抛出 SQLException。默认值为空。如果未指定，连接将通过 isValid() 方法进行验证。示例值为 SELECT 1(mysql)、select 1 from dual(oracle)、SELECT 1(MS Sql Server)

鉴于您正在使用适用于 MSSQL 和 Sybase 的 JDBC 驱动程序，您可以尝试使用 SELECT 1 作为验证查询：

如果其他参数正确，它应该可以解决您的问题：
