在PCF上部署时，SCDF V1.6.0-RELEASE不断崩溃

我要求将计划的任务迁移到SCDF中集成的PCF Scheduler。当开始使用清单文件应用程序进行部署时，由于与数据库连接相关的错误消息而不断崩溃。我正在使用用户定义的服务连接到MySQLDB。

这与我以前的V1.3.0-RELEASE版本中使用的清单相同，并且按预期工作。

答案 0 :(得分：0)

从1.5开始，我们将连接池机制切换为由Hikari管理。 Spring Boot也将其默认切换。可以从spring-cloud/spring-cloud-dataflow#2169，spring-cloud/spring-cloud-dataflow-server-cloudfoundry#417和spring-cloud/spring-cloud-dataflow-server-cloudfoundry#415中找到有关其原因的更多背景信息。

有了此支持，您可以通过声明性配置控制池的大小-请参见here。

除了用于自定义的新配置属性外，我们无需在v1.5及更高版本中进行任何设置。

最好回顾一下cf push以来的整个堆栈跟踪，直到出现错误为止。另外，您可以编辑该帖子，以包括您在VCAP_SERVIVCES中看到的scdf-server环境。可能是由于CUP服务对数据源凭据的JSON解析格式与spring-cloud-connector可以解释的格式不同，而我们内部依赖。{p>
