Tungsten Clustering 5.3.6 and Tungsten Replicator 5.3.6 Released

Continuent is pleased to announce that Tungsten Clustering 5.3.6 and Tungsten Replicator 5.3.6 are now available!

Our 5.3.6 release fixes a number of bugs and has been released to improve stability.

Highlights common to both products:

  • Now, instead of searching for a master with appropriate role (i.e. matching the slave preferred role) until timeout is reached, the replicator will loop twice before accepting connection to any host no matter what its role is. (CT-712)
  • Changing the state machine so that RESTORING is not a substate of OFFLINE:NORMAL, but instead of OFFLINE so that a transition from OFFLINE:NORMAL:RESTORING to ONLINE is not possible any longer. Now it will not be possible to transition from
  • When an heartbeat is inserted, it will now use the JVM timezone instead of hardcoded UTC. (CT-803)
  • Now skipping files that are not valid backup properties files (i.e. 0-byte store* files or with invalid dates). (CT-820)

Highlights in the clustering product:

  • Don't try to backup a witness server. (CT-669)
  • Create a Nagios script to check policy. (CT-675)
  • Fixing the output of tpm diag to include the simple form of cctrl ls for each dataservice. (CT-681)
  • Validation check MySQLMyISAMCheck is faulty and has been removed. (CT-756)
  • 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 from restarting the connectors during the automated update processing. (CT-792)
  • Make an INI-based role change during upgrade an error rather than a warning, since this is not best practice. (CT-801)
  • The Connector has been modified to get the driver and JDBC URL of the datasource from the Connector-specific configuration, overriding the information normally distributed to it by the manager. This prevents the Connector from using incorrect settings, or empty values. (CT-802)
  • Obfuscating clear text Manager passwords found in tpm diag. (CT-822)
  • Fixed the script template to avoid failures with signed / unsigned timestamps difference that occurs under edge conditions. (CT-824)
  • Prevent cctrl from hanging by putting the replicator online asynchronously. If the master is offline it will go to the SYNCHRONIZING state. As the master comes online the slaves will come online also. (CT-825)
