What to do if the database file is garbled when it is converted to a CSV file.

Phenomenon

Use DB.Browser.for.SQLite to export data from the database to a CSV file. But this CSV file is garbled.

Cause

Database files of NcCloud are encoded in UTF-8. However, a CSV file does not specify the encoding format. Therefore, if you open the file in Microsoft Excel in wrong encoding format, Chinese characters may become unreadable characters.

Solution

Manually set or select the encoding format when you open the CSV file.

Can I access xFactory with a domain name?

Phenomenon

You can access xFactory with a domain name.

Solution

Once xFactory is deployed in working environment, you can access xFactory by inputting its IP address in any devices within the same network segment.

Taking 192.168.12.79 as an example, to access xFactory with the corresponding domain name, do one of the following:

• To parse the domain name equivalent to the IP address of xFactory, add a rule of parsing the domain name to enterprise network DNS server, that is, .

  Parse dnc.weihong.com.cn or other domain names to 192.168.12.79
  

• Modify file hosts .

  1. In the target computer, open file hosts as an administrator.

     The default path of the file is C:\Windows\System32\drivers\etc\hosts.

  2. Add the following line in file hosts:

     192.168.12.79 dnc.weihong.com.cn
