File Transfer Governance

A quick guide for different file transfer methods in DWB.

File Tranfer Governance is a standard process to transfer files from an internal directory to any other server or internal file movement.

Different File Tranfer Methods

1. AWS (Amazon Web Services)

   1. Raise a Ticket to install AWS command line interface on server if not already installed (see https://docs.aws.amazon.com/cli/latest/userguide/installing.html).
   2. How to Check? Try to configure the AWS using command prompt (see https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html).

2. Transfer files from FTP server to NAS directory.

   1. FTP offline feeds from ftp server to NAS directory. The details below are required for FTP.

      ftp_username

      ftp_password

      ftp_port

      ftp_address

      ftp_directory

      delete_ftp_files

      ftp_file_extension

      local_directory

      (FTP Details will be available in project checklist. Use external ftp user for transferring the files)

   2. Use ftp_winscp_get.pl script attached below and schedule based on requirement.

      ftp_winscp_get.pl

      This script should be placed at E:\scripts\Scripository\Library\Perl

      NOTE

      If Scripository folder is not available see Weekly Reprocess to download the folder.

   3. Schedule the script based on files availability at ftp_address.

   4. Naming convention of file should be YYYYMMDD-<offline_feed_name>-00.*

3. Transfer files from NAS directory to FTP server.

   1. Use ftp_winscp_put.pl script and schedule based on requirement.

      This script should be placed at E:\scripts\Scripository\Library\Perl

      The details below are required to run the script.

      ftp_username

      ftp_password

      ftp_port

      ftp_address

      ftp_directory

      delete_ftp_files

      ftp_file_extension

      local_directory

       runLogger("$pluginname: creating temporary winscp file");
      
      }
      

   2. Schedule the script based on files availability at ftp_address.

   3. Naming convention of file should be YYYYMMDD-<offline_feed_name>-00.*

4. Transfer Files from one NAS directory to other NAS directory.

   1. Copy and paste file directly connecting to one NAS directory from other. Follow below process:)

      login to server -> go to Run -> \server_name\E$ [new folder will open and directly copy or move the files]

   2. Use “copy_files.pl” script to copy files from one server to other or “move_files.pl” to move files from one server to other. (These files are available in E:\scripts\Scripository)
