在尝试创建新的 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。

Exception thrown by application class 'org.lightcouch.CouchDbClientBase.executeRequest:-1'

我不太确定 CouchDB 与 dashDB 有什么关系,但无论如何,改天,另一个不优雅的处理。

我明天再试一次,通常会解决它。

根据您的描述,您在尝试启动控制台以管理您刚刚创建的 dashDB 实例时遇到上述错误。

这证实了您看到的异常,特别是这一行:

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

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

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