Version End of Life. 15 Aug 2024
Release 6.1.18 contains a number of minor bug fixes and improvements.
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 tungsten_find_orphaned command now places the log file in
In this release, the backups will now create the backup and then manually compress it
This change will increase the required disk space for backups to allow the post-backup compression to complete.
The tungsten_merge_logs command now supports the
--before TIMESTAMP and
--after TIMESTAMP filters
The tungsten_generate_haproxy_for_api and tpm generate-haproxy-for-api commands
now support using connector hosts in the backend definitions via
-c, and extra backend flags to the
backend hosts lines using
The tungsten_generate_haproxy_for_api and tpm generate-haproxy-for-api
commands no longer call the
Perl Data::Dumper module.
The tungsten_reset_manager command now supports the ability to simply print out the path or paths to be cleared,
one per line via the
The thl list command now displays an approximative field size in bytes for row-based replication.
This will pause the given stage for 100 seconds.:
trepctl pause -stage thl-to-q -time 100
This will pause the stage indefinitely (or until restart, etc) Add -y to avoid the prompt message whether you are sure.
trepctl pause -stage thl-to-q
For the previous 2 commands, running a pause command again will override the previous command.
This will resume the suspended stage (Note that if the stage is not paused, this will have no effect):
trepctl resume -stage thl-to-q
Please note this pause does not survive a replicator restart or a service offline/online.
Added a new option to TPM
manager-replicator-offline-timeout=<timeout_in_sec> that configures the timeout for
the manager to wait until the replicator goes offline. When parallel applier is in use the default timeout was too low, so it’s now
user configurable so that it can be adjusted to suit different topologies. If not supplied, the default is 180 (3 minutes). This
value should be sufficent in most use cases.
undeployall script would not properly uninstall
services on some distributions including amazon linux.
The tpm diag command now gathers the mysql.log file when SSL is enabled in the server
The tpm diag command now behaves properly when the MySQL server is logging to STDERR.
Fixes an issue that would prevent a service from going offline at a specified time (trepctl online -until-time) when parallel apply is enabled. This is a rework of CT-1243.
Fixed a possible issue when recovering an old primary as a replica after failover when parallel apply is enabled, that could lead the replica to be unable to come online and require a reprovisioning of this replica.
Fixed an issue where filtered events would trigger a useless update to the service trep_commit_seqno table while it is overwritten anyway once the last statement of the applied event is done, just prior to committing the whole block.
