創建新的 FiwareService 時 Orion CB 中的錯誤 500

Question

我在 MongoDB 4.0.5 之上使用 Fiware Orion CB 版本 2.1.0。 一旦我啟動它，一切似乎都可以正常工作，但是，經過一段時間（幾天）攝取數據沒有問題，現在，每次我嘗試在新的 fiwareservice 中創建新實體時，我都會收到來自 OrionCB 的 500 錯誤（如果我嘗試在現有的 FS 中創建相同的實體，它可以工作），並且我必須重新啟動 Mongo 和 Orion 容器才能使這個新的 FS 創建工作。

更新：

這僅在嘗試創建新 FiwareService 時發生（通過在新 FS 中創建新實體）。 在已創建的 FS 中管理任何現有實體工作正常。

更新二：（根據評論）

> use orion-foo
switched to db orion-foo
> db.entities.insert({x:1})
WriteResult({
        "nInserted" : 0,
        "writeError" : {
                "code" : 8,
                "errmsg" : "1: Operation not permitted"
        }
})

Answer 1

考慮到 UPDATEII 中的信息，問題似乎出在 MongoDB 實例本身，而不是在 Orion 中。 我的意思是，mongo shell 的失敗表明數據庫本身不允許創建新數據庫（無論是誰在創建它們，無論是 Orion，你在 mongo shell 還是連接到 MongoDB 的第三個應用程序）。

因此，我建議檢查您的數據庫設置。 有點令人驚訝的是，根據報告，它在開始時有效，但一段時間后開始失敗。 也許某些帶外操作（即管理過程）正在移動中更改權限？
