We are pleased to announce the release of Tungsten Cluster and Tungsten Replicator v8.0.3, a focused maintenance release that delivers important stability fixes, Java compatibility updates, enhanced monitoring capabilities, and security library upgrades.
This version strengthens reliability across the stack while introducing improved visibility into replication performance.
Improved Stability & Java Compatibility
Several stability improvements have been made to the Tungsten Manager to address memory leaks that could lead to OutOfMemory conditions. These fixes significantly improve long-running cluster reliability.
Recent versions of Java introduced changes to default security behavior, specifically enabling endpoint identification in secured RMI calls. This behavior impacted Tungsten environments running on newer Java versions. Tungsten v8.0.3 restores the previous default behavior within Tungsten scripts to ensure continued compatibility and stable operation without requiring immediate environment-level adjustments.
Real-Time Replication Performance Monitoring
Tungsten Replicator v8.0.3 enhances observability by introducing real-time performance monitoring to track slow database operations during replication.
This feature provides visibility into transaction, event, and statement execution times, with configurable thresholds to help identify performance bottlenecks early. Administrators can leverage the trepctl perflog command to analyze replication latency and proactively troubleshoot slow queries before they impact downstream systems.
Security Updates
As part of ongoing security hardening, this release includes updates to the log4j libraries to mitigate potential vulnerabilities found in earlier versions. While default Tungsten installations are not affected when using standard log4j configuration files, updating ensures environments remain aligned with current security best practices.
Installation & Operational Fixes
Several important fixes improve installation and provisioning workflows. An issue affecting installations using MariaDB 10.6 with SSL has been resolved. Previously, these deployments could fail during MySQL login validation.
The tprovision command has also been fixed to correctly handle passwords containing double quotes. In certain backup and restore scenarios, newly provisioned databases could be left in offline_mode; this behavior has now been corrected.
Connector & Cluster Stability Enhancements
Tungsten Connector includes a fix for a rare startup-time null pointer exception, improving reliability during initialization.
Within Tungsten Cluster, enhancements to the tpm ini check command introduce stricter validation rules for configurations using active witnesses. These checks help prevent misconfiguration in environments leveraging witness-based high availability.
Upgrade Notes
Tungsten Cluster & Replicator v8.0.3 is recommended for all v8 users, particularly those running on newer Java versions or experiencing memory pressure in Manager processes.
As always, we recommend reviewing the full release notes and validating upgrades in a staging environment before deploying to production.
