Question

我尝试使用WPLT 6.6加载测试部署在Weblogic服务器上的ADF网站。当我重播单个事务时，一切正常，当我尝试为一个用户加载测试时一切正常，但当第二个并发用户进入测试时，服务器响应有500个错误（验证）。我不知道是什么问题。

以下是性能测试期间HTTP 500的最常见原因

未能检查每个请求是否有正面预期结果（不仅仅是HTTP 200），然后在发生意外结果时无法分支代码。然后，HTTP 500在超过具有意外响应内容的有效HTTP 200请求响应的点出现的一行或两步之后发生。最终结果是下一个（或可能是下一个）请求与业务流程的状态脱离了上下文。作为开发中未处理的异常（因为自然用户无法进展），会产生HTTP 500结果。

至于业务流程为何脱轨？原因很多。您可能有一些与会话，状态，时间，安全令牌，用户凭据，业务流程数据/密钥等相关的未处理动态数据...您可能拥有与业务流程所需的状态不同的数据，例如尝试重复使用，使用一次数据。如果您共享环境并同时与其他组测试数据，您甚至可能让其他人在测试期间更改数据状态。

如果您没有主动检查测试代码中每个测试步骤（测试101的东西）的正面预期条件，那么您正在做的是＆＃34;抛出负载＆＃34;并且应该预期和共同使用这些类型的HTTP 500错误。

在weblogic的负载测试中收到500错误
