擷取工作時發生錯誤

Cause

此錯誤可能與檔案權限錯誤有關：

檢查以確認問題 connectionmanger.log 與 deploymanager.log

Connectionmanager.log 如下所示。

Resolution

1.在 Avamar 上以 root 身分檢查檔案權限：

ls -ltrh /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

結果如下所示：

-r-------- 1 admin admin 4.5K /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

2.變更權限 preferences.dtd.

chmod 444 /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

檔案權限現在如下所示：

 r--r--r-- 1 admin admin 4.5K /usr/local/avamar/var/mc/server_data/prefs/preferences.dtd

3：請確定沒有執行任何備份，然後重新啟動 tomcat 服務：

emwebapp.sh --restart


代理部署管理員現在可用於重新部署代理。
如果最近未部署代理，則沒有任何選項可在 PDM 中升級代理。
手動部署它們並刪除舊代理。
