DTS: What's New

    * Dec 2, 2021 Added mailed error if dts.config or dts.sitelist are not correct

    * Aug 2021 - DTS 9.2.0

    • Replace mail and related routines (steal_mail, lockmail.pl, etc.) with mail messages written to an FTP area for all data-related communications between systems. Uses checksum files as “data ready for pickup” notice files to indicate the presence of new data availability messages.
    • Added use of Net::SFTP::Foreign perl library to improve error trapping and graceful handling of error conditions with SFTP connections.
    • Removed dts.config settings specific to mail and lockmail (ignored if left in place)
    • Added self-locking feature to prevent a new DTS instance from running if an earlier one is still processing.
    • Support for SFTP with SSH keys, with or without a passphrase, and SFTP with passwords.

    • Removed zero-length log cleanup (occasional unintended deletions).

    * Feb 2016 - DTS 7.1.0

    • Introduction of “lockmail” routine to prevent conflict when “stealing mail” from the dtsmail account. Aded LOCK_TIMEOUT, LOCK_ATTEMPTS and LOCK_PROTOCOL settings to dts.config to configure lockmail settings.
    • Introduced log file housekeeping to remove zero length log files
