2.12. Tungsten Replicator 6.1.20 GA (19 Dec 2022)

Version End of Life. 15 Aug 2024

Release 6.1.20 contains a number of critical bug fixes and improvements.

Behavior Changes

The following changes have been made to Tungsten Replicator and may affect existing scripts and integration tools. Any scripts or environment which make use of these tools should check and update for the new configuration:

  • Command-line Tools

    • Both the tungsten_get_ports and tpm report commands have been updated to use the ss OS command when the netstat OS command is unavailable or deprecated.

      Issues: CT-2007

Improvements, new features and functionality

  • Command-line Tools

    • A new command has been added called tungsten_get_ports, which will display the running Tungsten processes and the associated TCP ports that those processes are listening on.

      Issues: CT-1970

    • The tungsten_get_ports command now supports the /opt/continuent/tungsten/tungsten-connector/conf/interfaces.json file, if found.

      Issues: CT-2003

    • The tungsten_get_ports command now use values based on values obtained from tpm query values when possible for the greatest output accuracy.

      Issues: CT-2008

Bug Fixes

  • Command-line Tools

    • Worked around a ruby issue where DNS name resolution was sometimes preferred to file-based resolution in TPM. The following logic now applies: first trying file-based host name resolution, upon failure try DNS, then through ping command

      Issues: CT-1653

  • Core Replicator

    • Fixed an issue in the applier to ensure it is not committing too often with a multi-service replicator (active/active for example, more specifically with AWS Aurora, or an unprivileged MySQL, backend).

      Issues: CT-2004

  • Filters

    • Fixed an issue where the dropsqlmodes filter would fail to remove invalid sql modes from a multi-statement event

      Issues: CT-1993
