Version End of Life. Not Yet Set
Release 6.1.8 is a minor bug fix release.
tungsten_post_process (in [Tungsten Clustering (for MySQL) 6.1 Manual]) now handles whitespace properly on
property= lines in INI files.
Fixes an issue that would prevent a service from going offline at a specified time (trepctl online -until-time (in [Tungsten Clustering (for MySQL) 6.1 Manual])) or at a specific seqno (trepctl online -until-seqno (in [Tungsten Clustering (for MySQL) 6.1 Manual])) when parallel apply is enabled.
Managers now accept both unencrypted and TLS connections from connectors. This allows migrations when security is enabled from earlier versions to 6.1.2+, as well as seamless switch to encrypted connector-manager communications.
When upgrading to this release from an earlier release, and SSL is either already enabled, or being enabled as part of the upgrade, it is important that managers are upgraded before the connectors.
Note that non-secured connectors connections will trigger a warning in the manager logs:
WARN [RouterGatewayServer] - Un-encrypted connection request from <connector address> while this manager » is configured to use SSL. This is expected ONLY when migrating manager<>connector communication to SSL. » Otherwise it might be a misconfiguration of this connector.
A network partition between primary and relay sites with port 11999 still functioning was leading to full connectivity outage. Managers now send data services configuration with every node update (one per node every 3s) so that connectors remain up-to-date even in that corner case.
