【问题描述】：

1.首先我使用 h2 数据库集群 apim 和 das .APIM 和 DAS 可以很好地相互配合

2.当我换了mysql，APIM也不错，但是DAS不行。那我就看不到数据了。

【问题讨论】：

您在查看统计数据时还有什么问题吗？你说then i can watch stats。此外，该 cApp 已成功部署。
对不起，我的错。我吃我的“不”。我的统计数据仍然不起作用。

【解决方案1】：

根据 [1]，这应该是由于现有的 cApp。当您将数据库更改为 mysql 时，首先您必须删除 DAS_HOME/repository/data 文件夹，以及 DAS_HOME/tmp 目录。
