Question

我有一个grails应用程序成功运行在cloudfoundry中，H2作为数据库。我现在想切换到postgresql。当我在本地针对postgreSQL运行应用程序时，一切都按预期工作。

在cloudfoundry实例上，我在一次相当长时间运行的分析中遇到异常，我将其作为后台任务执行（使用grails executor插件）。在这个异步任务中

def future = executorService.submit({
    return analysisService.analyzeProject(model, project)
})

我从数据库中获得以下异常：

任何可能导致这种情况的想法？

你有可能在长时间运行的连接中遇到配置的超时（如果我没有弄错的话，这是不能改变的，因为这是为了保护服务器免受生成的查询，这会消耗所有的cpu / io）< / p>

您可能想要尝试的是将长时间运行的查询切分为较小的查询并总结结果（如果是选择）

cloudfoundry上的PostgreSQL抛出PSQLException：FATAL：由于管理员命令而终止连接
