IBM Worklight應用程序中心訪問異常

Question

在服務器上安裝了Worklight AppCenter，並顯示所有日誌顯示已成功安裝（數據庫和Web應用程序）。服務器也啓動沒有任何問題。使用Chrome瀏覽器訪問時。登錄成功但獲得500錯誤：發生意外錯誤（HTTP狀態500）。詳細日誌如下：

Answer 1

HTTP狀態500指REST服務已經發出異常。根據跟蹤，它看起來像數據庫是不正確的，特別是沒有創建表。 所以你可以看看APPCNTR數據庫並檢查表是否被創建。如果沒有，您可以運行可在目錄/ ApplicationCenter/Databases中找到的SQL腳本。

我最後一次看到這個異常，就重新啓動了應用程序服務器。
