Version End of Life. Not Yet Set
Release 7.0.1 is the first minor release for the v7 release. This release contains a number of new features, minor bug fixes and a few key behavior changes, but importantly contains a critical bug fix for environments that use mixed-case table and database names, that could cause replication failures.
Customers already running v7.0.0 in production enviornments should upgrade to this release as soon as possible
The following changes have been made to Tungsten Cluster 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 cctrl output now displays the SSL status of the group communication and the connection to the database.
$ cctrl Tungsten Clustering 7.0.0 nyc: session established, encryption=true, authentication=true jgroups: [un]encrypted, database: [un]encryptedIssues: CT-1785, CT-1832
The tpm ask summary command is now sorted by key when the Perl
Tie::IxHashmodule is installed.Issues: CT-1820
The following commands which call cctrl now support the pass-through
-t secondstimeout argument which specifies how long cctrl will wait for a connection to the Manager process before aborting:
check_tungsten_latency
check_tungsten_online
check_tungsten_policy
check_tungsten_services
tungsten_show_processlist
zabbix_tungsten_latency
zabbix_tungsten_online
zabbix_tungsten_progress
zabbix_tungsten_services
Issues: CT-1822
The tpm diag command now gathers the output of the tpm ask summary command
Issues: CT-1827
The tmonitor command now calls sudo internally as needed, removing the need for the tmonitor command to be run with sudo for the install and remove sub-commands.
Issues: CT-1846
The tpm generate-haproxy-for-api default starting port is now 8091.
Issues: CT-1865
The tungsten_find_orphaned command now places the log file in
$CONTINUENT_ROOT/service_logs/, not/tmp/Issues: CT-1866
The default value for the tpm property
repl-svc-fail-on-zero-row-updatehas been changed fromwarntostopWarning
This is a significant change in behavior and could cause replicators, specifically cross-site replicators, in an Active/Active environment to stop and error more frequently.
To maintain original behavior you will need to add this property with the value of
warnto your configuration, providing you fully understand the inherent risk of ignoring such warnings.Issues: CT-1856
The following issues are known within this release but not considered critical, nor impact the operation of Tungsten Cluster. They will be addressed in a subsequent patch release.
After starting up Tungsten components, a
defunctprocess for each running component can be found in the process listing.Whilst this does not cause any issues, it could generate unnecessary alerts for customers monitoring.
The cause has been identified and affects version 7.0.0 and 7.0.1. This will be fixed in the next 7.0.2 release.
Issues: CT-1876
Improvements, new features and functionality
Added the ability to turn auto recovery on or off dynamically, removing the need to run tpm update.
This is done by running the following command:
shell> trepctl -service servicename setdynamic -property replicator.autoRecoveryMaxAttempts -value <number>The service must be offline before changing the property
Issues: CT-1088
The new command tungsten_upgrade_manager will help clear specific cached SSL values, to be used only when specified by Continuent Support.
Issues: CT-1788
A new tpm report sub-command has been added. By default, tpm report will generate a security report for all available communication channels on a per-node basis. The purpose of tpm report is to provide easy access to all of the settings that pertain to a specific topic. The default (and only) topic at this time is the security stance. More topics will be added over time.
Issues: CT-1793, CT-1857
The tapi command now supports the creation and modification of multiple
APIv2 admin users. Two new cli args have been added: --create-user and --create-pass.
Issues: CT-1801
The tapi command now auto-detects the protocol, either http or https
Issues: CT-1803
Added connector<->manager link encryption status in the output of router * status command in cctrl
Issues: CT-1811
Added JMX encryption and authentication status to trepctl -verbose and connector command outputs
Issues: CT-1813
The tapi command will now output service names with the
new option --includeServiceName, or if there is more than one service name found.
Issues: CT-1860
Added a way to retrieve service properties through the API, for example, to check a specific service parameter, run the following API call :
shell> curl https://127.0.0.1:8097/api/v2/replicator/service/alpha/properties?filter=replicator.global.db.sslEnabled
{
"payloadType": "PropertiesListPayload",
"payloadVersion": "1",
"payload": {
"replicator.global.db.sslEnabled": "false"
}
}Issues: CT-1802
Added new top level REST API call to display RMI SSL status, run the following API call :
shell> curl https://127.0.0.1:8097/api/v2/rmiSecurityIssues: CT-1812
The tpm update command now properly handles v7 -> v7 upgrades.
Issues: CT-1815
deployall script now properly displays the executable prefix for restarting services, typically mm_treplicator in Multi-Site/Active-Active replicator-only installs, as well as the full path to component binaries
Issues: CT-1835
tpm would fail on keystores containing special characters in alias names.
Issues: CT-1852
Worked around a ruby issue where DNS name resolution was sometimes preferred to file-based resolution in TPM. The following logic now applies: first trying file-based host name resolution, upon failure try DNS, then through ping command
Issues: CT-1653
The tpm update command now returns clusters to the proper mode (i.e. maintenance
or automatic) for staging-method upgrades (INI not affected).
Issues: CT-1784
The tpm policy command now returns the proper policy in a composite cluster. There
is also a new cli argument, --all, to show the policy for all cluster services.
Issues: CT-1787
The tpm update command no longer aborts during a staging deployment when the actual hostname does not match what is configured for the node names in tpm
Issues: CT-1791
Improves the tpm diag command so that it waits 2 seconds for replicator thread dump to complete.
Issues: CT-1792
Fixed an `Undefined subroutine` call error in tapi --create
Issues: CT-1798
The tpm connector command now properly passes the -e arguments to the mysql command.
Issues: CT-1816
tpm now properly reports errors upon timeout executing commands. Typically, when a host is down, when upgrading or installing, tpm will now properly report that pinging this host failed.
Issues: CT-1819
The tpm update command now properly determines services to be deleted.
Issues: CT-1825
TPM would fail to validate data sources when using ssl-capath [directory] rather
than ssl-ca [file] in my.cnf.
This fixes only the validation part, automated truststore creation by TPM will not be possible at
this point, a full tungsten-truststore.ts will have to be passed through
--java-truststore-path
Issues: CT-1826
The tapi command now auto-switches protocol (http or https) properly.
Issues: CT-1829
replicator start offline would not properly pass the offline argument to systemd scripts when installed through deployall.
Issues: CT-1836
undeployall script would not properly uninstall systemd
services on some distributions including amazon linux.
Issues: CT-1845
Fixed an issue with latest xtrabackup 8.0.28
Issues: CT-1838
During the backup/restore process the MySQL certificates are kept intact.
Issues: CT-1841
Restore will now succeed even if only one incremental backup has been created.
Issues: CT-1842
Incremental backups can now be restored more then once.
Issues: CT-1850
Fixed the EnumToString and pkey filters to renew their database connections (every hour by default). This can be changed with the following properties:
property=replicator.filter.enumtostring.reconnectTimeout=3600 property=replicator.filter.pkey.reconnectTimeout=3600
Issues: CT-1786
tpm update would fail with message "The host is configured to be '' but it is currently operating as a 'master'"
when a dynamic replicator configuration file is found
Issues: CT-1848
Fixes issues with PrimaryKeyFilter:
It could fail from correctly fetching primary key columns for tables with mixed upper and lower case letters in table names
Alter user statements could make it fail
Issues: CT-1861
Fixed a NullPointerException that could happen if a replicator was put
offline during startup. This had mostly no consequence except the exception being logged.
Issues: CT-1863
