A.1. Tungsten Clustering 8.0.3 GA (23 Feb 2026)

Version End of Life. Not Yet Set

Release 8.0.3 contains an important bug fix to handle a behavior change in newer bersions of Java, stability improvements with the Manager to fix a number of memory leaks, and a new feature for tracking slow queries through the replicator.

Behavior Changes
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:
Command-line Tools

The tpm ini check command now checks for two new rules:

There MUST be a witnesses= entry in EVERY stanza if enable-active-witnesses=true exists in [defaults]
There MUST be a witnesses= entry in a stanza that contains enable-active-witnesses=true

Issues: CT-2625

Improvements, new features and functionality

Core Replicator

The replicator now includes real-time performance monitoring to track and identify slow database operations during replication. The feature provides visibility into transaction, event, and statement execution times with configurable thresholds for alerting. For more information on configuring and using this feature, see Section 9.25.3.15, “trepctl perflog Command”

Issues: CT-2629

Security

Updated log4j libraries to mitigate security threats found in earlier versions. Note that these issues do not affect Tungsten installations when configured with the default log4j properties files.

Issues: CT-2674

Bug Fixes

Installation and Deployment

Fixed an installation issue when using MariaDB 10.6 with SSL. Previously, this would have failed to install showing an error message like :
```
Unable to connect to the MySQL server using tungsten@db1:13306 (WITH PASSWORD) (MySQLLoginCheck)
```
Issues: CT-2624

Command-line Tools

Fixed a bug that would cause tprovision to fail if the password contained double-quotes.

Issues: CT-2673

Backup and Restore

Fixes an issue when, in certain cases, a newly provisioned database would be left in the offline_mode.

Issues: CT-2660

Core Replicator

Recent java versions changed a default that now enable endpoint identification in secured RMI calls. As a quick turnaround, this release restores the default of disabling identification in various Tungsten scripts.

Issues: CT-2666

Tungsten Connector

Fixed a null pointer exception error showing up in rare cases at startup time.

Issues: CT-2656

Tungsten Manager

A number of bugs have been resolved that would cause the managers to suffer frequent OutOfMemory issues.

Issues: CT-2667
