Replicating weblinks

Post by manair »

We have two WingFTP servers and replicate the XML config files and user data files between them using DFSR. This works well apart from since the move from flat files to the SQLite Database for weblinks. If a user creates a Weblink on one server and a recipient tries to download the file on the other it obviously fails. Is there a method to replicate the tables with bookmark_db between the servers?

So please try to copy the file "Data/bookmark_db" from the old server. If still fails, please contact us via support email.

This is not a one off copy. We have two servers active for resilience. As the file is open by the server DFSR does not replicate it in a timely manner.

I have written a PowerShell script that copies new entries from one database to the the other and visa-versa, I'll test it for a few days and post here if it works.

Our setup is two WingFtp Servers with a shared IP using Microsoft NLB.
The _weblinks, groups, users and user data (uploaded files) folders are replicated using windows DFSR.
This has always been enough in the past, but with the introduction of the bookmarks_db database weblinks broke in our setup.

The following PowerShell script running every minute from a scheduled task has resolved this gap.
Please excuse any bad practice in the code, I'm not a developer and the script works, so good enough for me.

Code: Select all

#Requires -Modules pssqlite
<#
    Used to keep WingFTP weblink database sync with partner server
    Will remove any entries from databases that does not have a corresponding file in the _Weblinks folder on either server
    Will add entries to database if missing and found on partner server.
    Shares must be created to allow account running scripts access to _Weblinks folder and databases

If restarting the WingFTP service will let the new created weblink work, then I think maybe the SQLite records were not inserted really, at least WingFTP can't read the new records. So please check the related SQLite operation part.

Another method is using a shared folder to store weblink files and SQLite db file, you can set shared folders under "Server > Settings > General Settings > Miscellaneous", like this:

After configuring the above settings, you also need to copy the file "Data/settings.xml" into another WingFTP server.

BTW, the same domain ID is necessary for all the WingFTP servers, and if you want to keep the same weblinks, you had better use Mysql/ODBC database for storing user accounts, then all the servers will share one copy of the user account.
