尝试创建新的dashDB实例后，在尝试“管理”这个新购买的实例时会抛出明显非Netezza / DB2错误。

我不太确定CouchDB与dashDB有什么关系，但无论如何，另一天，另一天不合理地处理。

我明天再试一次，这通常会解决它。

根据您的描述，在尝试启动控制台以管理刚创建的dashDB实例时，您会收到上述错误。

这确认了您所看到的异常，特别是此行：

com.ibm.datatools.dsweb.controller.RestEndPoint.launchDashboard(RestEndPoint.java:513)

dashDB控制台是一个Web UI，后端使用Cloudant NoSQL DB开发，后者基于Couch DB。因此，您看到了Couch DB异常。

Cloudant NoSQL DB在您尝试启动时可能处于脱机状态，但我同意应该正确处理异常。我将创建一个内部缺陷，以使dashDB团队为此提供修复。
