Version End of Life. 31 July 2020
Release 6.0.5 contains both significant improvements as well as some needed bugfixes.
Improvements, new features and functionality
A new utility script has been added to the release, tungsten_reset_manager, which assists with the graceful reset of the manager's dynamic state files on disk.
Issues: CT-850
For more information, see The tungsten_reset_manager Command.
Do not try to backup a witness server.
Issues: CT-669
Include additional views of cctrl output in tpm diag (cctrl_status_simple_SVCNAME).
Issues: CT-681
The MySQL MyISAM check seems to fail intermittantly with no way to bypass it so the check has been disabled completely.
Issues: CT-756
Fixed an issue where the tpm command would allocate inconsistent THL listener ports for the Composite Active/Active topology.
The new, correct behavior is for the main cluster replicator to always be allocated port 2112, and then relay sub-services are incremented per remote cluster.
For example, in a 4-site CMM deployment, ports 2112 through 2115 would be allocated - 2112 for the main cluster and 2113, 2114 and 2115 for the remote site relays.
Issues: CT-799
The tpm diag command now collects cctrl status without a "WARNING: Unrecognized option 'multi'" error.
Issues: CT-821
Remove any clear-text passwords gathered via tpm diag.
Issues: CT-822
Fixed NullPointerException in cctrl 'ls -l' output when the dataserver is down.
Issues: CT-826
Fixed a case when get_replicator_roles and cctrl ‘ls -l’ didn't work if a replicator was stopped.
When a replicator is not running insert the
Replicator.HOST to the
ReplicationNotification. It was wrongly
inserted into the Replicator.DATASERVERHOST.
This fixes the get_replicator_roles script.
Also substituted hard-coded strings for their constant values.
Issues: CT-760, CT-876
mysql_checker_query script was returning unexpected errors and
creating false positives. Changed the script logic to use the
timestampdiff function for better accuracy.
Issues: CT-824
Change the Manager behavior so as to place the replicator online asynchronously to prevent cctrl from hanging if a Replica replicator is put online while the Primary is offline. Now, if the Primary is offline the Replica will go into the SYNCHRONIZING state. As the Primary comes online the Replicas will come online as well.
Issues: CT-825
Tungsten Clustering 6.0.5 Includes the following changes made in Tungsten Replicator 6.0.5
Release 6.0.5 is a bugfix release.
Improvements, new features and functionality
The
--hostsoption was not working with thediagsub-command of the tpm command on nodes installed using the INI method.The corrected behavior is as follows:
With Staging-method deployments, the tpm diag command continues to behave as before:
The tpm diag command alone will obtain diagnostics from all hosts in the cluster.
The tpm diag --hosts host1,host2,hostN command will obtain diagnostics from the specified host(s) only.
With INI-method deployments, the new behavior is as follows:
The tpm diag command alone will obtain diagnostics from the local host only.
The tpm diag --hosts host1,host2,hostN command will obtain diagnostics from the specified host(s) only.
Warning
Limitation: the host list MUST include the local hostname or the command will fail.
Issues: CT-345
The trepctl command now properly handles the
-all-servicesoption for theresetsub-command.Issues: CT-762
The command tpm reverse --ini-format now outputs correctly (without the double-dashes and the trailing backslash).
Issues: CT-827, CT-877
The command tpm diag was not collecting config dirs other than the localhost ones.
Now the mysql, manager, cluster and connector config directories are properly gathered in the diag zip file.
Issues: CT-860
The tpm command now properly handles network interface names containing colons and/or dots.
Issues: CT-864
Fixed an issue where the tpm command could print warnings about nil verify_host_key.
Issues: CT-873
The postgres applier now respects the database name set by pgsql-dbname.
Specifically, the
tungsten-replicator/samples/conf/datasources/postgresql.tplwas updated to use the correct variable for the value.Issues: CT-704
Instead of searching for a Primary with appropriate role (i.e. matching the Replica preferred role) until timeout is reached, the Replicator will now loop twice before accepting connection to any host, no matter what its role is.
Issues: CT-712
The backup process fails with 0-byte
store*.propertiesfiles orstore*.propertiesfiles with invalid dates.Changed the process so that invalid backup properties files are skipped.
Issues: CT-820
Fix the ability to enable parallel apply within a Composite Active/Active topology.
Now handling relay as Replica to make the relay use the same code as a Replica concerning its internal connections (disable binary logging of its internal SQL queries).
Issues: CT-851
