Learn what triggers Tungsten Cluster failsafe-shun and how it helps maintain high availability in MySQL database clusters. Discover key factors and best practices for managing automatic node shunning.

The Question

Recently, a customer asked us:

Why would heavy disk IO cause the Tungsten Manager and not MySQL to be starved of resources?

For example, we saw the following in the Manager log file tmsvc.log:

In this blog, we cover Continuents plans on the support model for the new MySQL “Innovation” releases.

If you are upgrading from MySQL 5.x to MySQL 8, using Tungsten Clustering or Tungsten Replicator, then you may need to prepare yourself for a little gotcha.

In this blog, Continuent’s CEO and Founder, Eero Teerikorpi, was prompted by a headline in the Finnish News to write about the MySQL and MariaDB business and ecosystem.

When was the last time you had an Urgent Support Request related to your MySQL deployment for your MySQL support or MySQL consulting provider? How fast were they able to come back to you? And was this by someone who actually could help you, or just a call center acknowledging your request?

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 7.0.2 are now available.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA versions 6.1.19 are now available. Tungsten allows enterprises running business-critical MySQL database applications to cost-effectively achieve continuous global operations with commercial-grade high availability (HA), geographically redundant disaster recovery (DR) and geographically distributed active/active.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 6.1.18 are now available. Tungsten allows enterprises running business-critical MySQL database applications to cost-effectively achieve continuous global operations with commercial-grade high availability (HA), geographically redundant disaster recovery (DR) and geographically distributed active/active.

In this blog, we discuss Galera Cluster and synchronous versus asynchronous replication. We also discuss some of the differences between Galera Cluster and Tungsten Cluster rooted in this difference in foundation. And how Tungsten has served a critical niche - mission-critical, geo-distributed, highly-performant MySQL applications - for a long time.

Tungsten Clustering is a powerful tool with many moving parts, including the Tungsten Connectors which may be installed on any application server. During a troubleshooting event, it is helpful to understand what to look for and where, in addition to understanding how the logs work together to provide a clear picture of the situation. In Tungsten version 7, we introduced a number of features designed to make troubleshooting easier, and this blog will cover some of that too.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA versions 7.0.1 are now available. This new minor release includes 52 new features and improvements, including two critical bug fixes. Read this blog to learn about the new v7.0.1 release!
