Version End of Life. 31 July 2020
This is a bugfix release.
When installing from an RPM, the installation would
automatically restart the connector during the installation.
This behavior can now be controlled by setting the parameter
no-connectors within the ini
configuration. This will prevent tpm (in [Tungsten Clustering (for MySQL) 5.3 Manual]) from
restarting the connectors during the automated update
A new Nagios compatible check script has been added to the release, check_tungsten_policy (in [Tungsten Clustering (for MySQL) 5.3 Manual]), which returns the currently active policy mode.
For more information, see The check_tungsten_policy Command (in [Tungsten Clustering (for MySQL) 5.3 Manual]).
During the lifetime of the cluster, switches may happen and the
current master may well be a different node than what is
reflected in the static ini file in the
master= line. Normally, this difference is
ignored during and update or an upgrade.
However, if a customer has some kind of procedure (i.e.
automation) which hand-edits the ini configuration file
master= line at some point, and such
hand-edits do not reflect the current reality at the time of the
update/upgrade, an update/upgrade will fail and the cluster may
be left in an indeterminate state.
The best practice is to NOT change the
master= line in the INI configuration file
Changed tpm check
WARN to ERROR to prevent changed
lines in ini files from breaking updates and upgrades.
Even with this fix, there is still a window of opportunity for
failure. The update will continue, passing the
CurrentTopologyCheck test and potentially
leaving the cluster in an indeterminate state if the
master= option is set to a hostname that is
not the current master or the current host.
Change the Manager behavior so as to place the replicator online asynchronously to prevent cctrl from hanging if a slave replicator is put online while the master is offline. Now, if the master is offline the slave will go into the SYNCHRONIZING state. As the master comes online the slaves will come online as well.
