提醒：NetWorker .raw 文件可以通过下列方式呈现：nsr_render_log /path/to/log.raw > out_filename 2<&1

Cause

在升级后，NMC 安装位置（例如：C:\Program Files\EMC NetWorker\Management\GST）中缺少 postgres_latest 符号链接，这是代码缺陷。

更改：将 Networker 服务器从 19.3 升级到 19.4。

Resolution

重新创建 postgres latest 符号链接
 
  1. 找到 postgres 11.1 文件夹： <Install_Drive>:\Program Files\EMC NetWorker\Management\GST\postgres
  2. 打开管理命令提示符并运行以下命令：
语法： mklink /D "path_to_new_symbolic_link  "path_to_11.1_folder”
示例： 
C:\Program Files\EMC NetWorker\Management\GST\logs>mklink /D "C:\Program Files\EMC NetWorker\Management\GST\postgres_latest" "C:\Program Files\EMC NetWorker\Management\GST\postgres\11.1" symbolic link created for C:\Program Files\EMC NetWorker\Management\GST\postgres_latest <<===>> C:\Program Files\EMC NetWorker\Management\GST\postgres\11.1
  1. 重新启动 gstd 服务：net stop gstd && net start gstd
