Known Issue

The following issues may affect the operation of Continuent Tungsten and should be taken into account when deploying or updating to this release.

  • It was previously impossible to change from a non-SSL installation to an SSL installation using self-generated certificates if an INI style configuration was being used. This can now be achieved by using the following command-line:

    shell> tools/tpm update --replace-release --replace-jgroups-certificate --replace-tls-certificate

    Issues: CT-442

  • Previously the system had been configured to dump heap files by default when the system ran out of memory which was useful for debugging by the development team. This has now been disabled.

    Issues: CT-604

Tungsten Clustering 5.3.1 Includes the following changes made in Tungsten Replicator 5.3.1

Release 5.3.1 is a bug fix release that adds support for the GEOMETRY data type in MySQL 5.7 and above, and a number of bug fixes.

Bug Fixes

  • Installation and Deployment

    • Support for the GEOMETRY data type within MySQL 5.7 and above has been added. This provides full support for both extracting and applying of the datatype to MySQL.

      This change is not backwards compatible; when upgrading, you should upgrade slaves first and then the master to ensure compatibility. Once you have extracted data with the GEOMETRY type into THL, the THL will no longer be compatible with any version of the replicator that does not support the GEOMETRY datatype.

      Issues: CT-403
