Advanced Tungsten Troubleshooting Using Log Files
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.

What Do We Mean By “MySQL”?
Tungsten is the go-to replication and clustering solution for MySQL - powering real-world, geo-distributed business-critical applications. Sometimes we get asked by those who are not familiar with us, what we mean by “MySQL,” and this blog is meant to shed some light on this question.
How We Enable Open Source Databases for Business-Critical Apps
One of the common misconceptions about Continuent is that because Tungsten does not have an open source license, we do not support open source. In fact, quite the opposite, in everything we do. The whole purpose of Tungsten Clustering is to empower and enable teams that build business-critical applications on open source databases.
This leads us to the subject of this blog: how Tungsten is designed for openness.
Service: Continuent’s Backbone
Hop on-board and sail the San Francisco Bay with the Founder and CEO of Continuent, Eero Teerikorpi, as he zeros in on one of the reasons customers love Continuent’s 24/7/365 customer service: speed. Of course, speed isn’t everything - but when combined with highly experienced and available DBAs, SysAdmins and Architects - it’s hard to find better peace of mind about your business-critical databases.
Easier Log Analysis with tungsten_merge_logs
The tungsten_merge_logs command is designed to aid troubleshooting by consolidating the various log files into one place (merged.log), ordered by time. There are many moving parts to a cluster and they are spread over multiple nodes (usually three). When there is an issue, the logs are the key resource to find out what is going on. The best practice is to gather the log files into one place and then read through them all. This can be difficult with many files on multiple nodes. For this reason, the `tungsten_merge_logs` tool was created.
How To Simulate a MySQL Cluster Site Failure with Tungsten
“How can I simulate a failure of the Active half of an Active/Passive Cluster to test the Failover to the Passive half?”
In this blog post we explore the best practices for simulating a failure of the Active cluster in an Active/Passive Composite Cluster.
How the VMworld 2021 Multi-Cloud Conference Built Its Global, Virtual Event on MySQL?
As we are all being pushed to the limit to meet unprecedented demands online, the pandemic shined a light on many new frontiers and achievements in technology. This blog is about continuous MySQL database operations when you have a global user base, particularly the VMworld 2021 Global Multi-Cloud conference.
Downtime with Coffee, not MySQL
MySQL High Availability (HA) is typically what architects and technologists look for in building business-critical and mission-critical applications, and they aspire to measure MySQL uptime in 4 or preferably more “nines.” This blog explores the modern world of continuous MySQL operations - cross-region, global, hybrid-cloud, and multi-cloud - and why you might need a different approach.
