問題 - ESB 4.5.1版

Question

我遇到訪問WSO2 ESB管理控制檯的問題：4.5.1版

當我登錄到控制檯，我收到了一大堆跟蹤並且不能訪問在esb上運行的任何功能/服務。

任何人都可以幫忙嗎？

堆棧下面跟蹤：

Answer 1

首先檢查，您有任何數據庫連接，將數據 基地是關機

如果確定，然後，再去。 www.wso2.org然後下載新的郵政編碼 文件，並將所有服務轉移到該服務器上。請檢查數據庫 是否啓動，然後啓動服務器。

希望這會幫助你，任何懷疑讓我知道..

Answer 2

看來，當你使用H2數據庫和wso2 proccess突然死亡問題發生。

在我的情況下，我正在用eclipse調試一個.arr服務（RemoteProvisioningServiceWS.aar），並且wso2在調試模式下啓動，eclipse凍結並且我必須殺死eclipse和wso2。當我試圖重啓wso2時，我正在調試的.arr顯然沒有正確加載。

如果你試圖打開服務聯合國的WSO2 Web控制檯的列表，並出現錯誤：

似乎是與數據庫中的一個問題，我不建議使用H2 db和在mySql中爲開發和生產環境配置wso2，只能在本地使用h2。

要解決該問題：下載相同版本的wso2解壓縮並複製或再次安裝所有服務和應用程序，重新啓動，一切都會恢復正常。

Answer 3

這可能是由於損壞的服務元文件。 您可以嘗試以下步驟。

1. 停工時，該服務器
2. 採取以下目錄的備份。 /repository/deployment/server/servicemetafiles
3. 刪除上述目錄的內容。
4. 啓動服務器。
