Version End of Life. 30 June 2018
Tungsten Replicator 5.0.1 is a bugfix release that contains critical fixes and improvements from the Tungsten Replicator 5.0.0 release. Specifically, it changes the default security and other settings to make upgrades from previous releases easier, and other fixes and improvements to the Oracle support and command-line tools.
The following changes have been made to Continuent 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:
The Ruby Net::SSH module, which has been bundled with Tungsten Replicator in past releases, is no longer included. This is due to the wide range of Ruby versions and deployment environments that we support, and differences in the Net::SSH module supported and used with different Ruby versions. In order to simplify the process and ensure that the platforms we support operate correctly, the Net::SSH module has been removed and will now need to be installed before deployment.
To ensure you have the correct environment before deployment, ensure both the Net::SSH and Net::SCP Ruby modules are installed using gem:shell>
gem install net-sshshell>
gem install net-scp
Depending on your environment, you may also need to install the
gem install io-console
If during installation you get an error similar to this:mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.hshell>
sudo apt install ruby-dev
The replicator (in [Tungsten Replicator 2.1 Manual]) is no longer restarted when updating the configuration with tpm (in [Tungsten Replicator 2.1 Manual]) when using the
--replace-tls-certificate(in [Continuent Tungsten 4.0 Manual]) option.
For compatibility with MySQL 5.7, the tpm (in [Tungsten Replicator 2.1 Manual]) command will now check for the
super_read_onlysetting and warn if this setting is enabled.
For compatibility with MySQL 5.7, the tpm (in [Tungsten Replicator 2.1 Manual]) command will use the
authentication_stringfield for validating passwords.
For compatibility with MySQL 5.7, the tpm (in [Tungsten Replicator 2.1 Manual]) command will now ignore the
The Rhino JS, which is incorporated for use by the filtering and batch loading mechanisms, has been updated to Rhino 1.7R4. This addresses a number of different issues with the embedded library, including a performance issue that could lead to increased latency during filter operations.
The Ruby Net::SSH libraries used by tpm (in [Tungsten Replicator 2.1 Manual]) have been updated to the latest version. This addresses issues with SSH and staging based deployments, including KEX algorithm errors.
On some platforms the keytool command could fail to be found, causing an error within the installation when generating certificates.
The tpasswd (in [Tungsten Replicator 2.1 Manual]) could create a log file with the wrong permissions.
