漫步@雲端

最近在測 IBM WebSphere Virtual Enterprise 7  時遇到了一個怪問題 , 當我在既有的 WebSphere Application Server Network Deployment 7 上安裝 WVE 7.0 , 並選擇擴充 (Extend) Dmgr01 及 AppSrv01 這兩個 Profile 後 , dmgr Process 啟動了 nodeagent 就起不來 , 反之亦然 , 並且出現下面的錯誤訊息 :

後來拜了一下 Google 大神 , 原來是節點沒有同步造成的 , 解決方法也很簡單 , 步驟如下 :

1. 確定 dmgr 的 Process (JVM) 是啟動並活著 ,  nodeagent 的 process (JVM) 已停止 .

2. 開一個 MS DOS  視窗 , 切換路徑到:

<WebSphere_Install_Root>\WebSphere\AppServer\profiles\AppSrv01\bin

3. 執行 :

syncNode.bat localhost -user wasadmin -password 123456

P.S.1 如果 WebSphere 沒有 Enable Console Security 則不需要下 -user wasadmin -password 123456

P.S.2 每個人的 WebSphere Administrator 的帳號 / 密碼 都不一樣 , 所以一定不是 wasadmin / 123456

4. 啟動 nodeagent , 打完收工 .
