Avamar 19.7：升级后 PDM 失败并显示 404 错误，preferences.dtd 不正确

升级到 19.7 后，PDM 失败并显示：

Error while fetching tasks. Failed with HTTP error code: 404 additional information
HTTP Status 404 - Not Found.

此错误可能与文件的错误权限相关联：

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

通过检查 connectionmanger.log 并且 deploymanager.log

Connectionmanager.log 如下所示。

1.以 root 用户身份在 Avamar 上，检查文件权限：

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

结果如下所示：

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

2.更改 preferences.dtd.

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

文件权限现在如下所示：

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

3：确保没有正在运行的备份，然后重新启动 tomcat 服务：

emwebapp.sh --restart

Proxy Deployment Manager 现在可用于重新部署代理。
如果最近未部署代理，则在 PDM 中没有任何升级它们的选项。
手动部署它们并删除旧代理。
