Transaction History Log (THL) files are the core of Tungsten Replication, containing the actual MySQL write events that are replicated to the replicas. These files can take up considerable amounts of disk space, making them of interest for housekeeping operations to limit the consumption and ultimately, the cost. This blog post will walk you through THL management, along with the new command `tpm purge-thl` which helps automate the process when THL needs to be removed prior to the automatic rotation window.

Thinking transparent reconnects of applications is the grail of HA? It is! But Active/Active setups make them risky.

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!

Performance tuning any system provides more speed for the same hardware spend, gives the end-user a better, faster experience and typically reduces the stress on staff all around. Security tuning locks down critical data to prevent unauthorized access. Today we will explore both the security and performance enhancements available for the Tungsten Replicator THL sub-system as of version 7.x.

Sometimes you really, really want to know what a MySQL client is asking of the MySQL server. As of Tungsten Clustering v7.0.0, you may now enable Connector Audit Logging, which captures data transferred between client applications and MySQL servers to a file, database or socket. This blog post will walk you through the feature and how to enable, configure and disable Tungsten Connector Audit Logging.

Deploying Composite Active/Active clusters gives end-users the best experience no matter where they are located. Tungsten Cluster makes this possible with the deployment of MySQL clusters at geo-scale, allowing the enterprise to host clusters close to the users. How can we avoid write-conflicts with asynchronous replication and multiple primary databases?

In this post we will explore a new command in v7.0.1, tpm report. The purpose of tpm report is to provide easy access to all of the settings that pertain to a specific topic. Since Security is a high priority at Continuent, the current default (and only) topic is the Security stance. The tpm report command will evolve and grow over time. This first version is Continuent’s way of providing as much transparency about Tungsten Cluster Security as possible.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 6.1.17 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.

Scalability is necessary to keep your database from crumbling under increased traffic. A scalable database must be able to handle larger data sets and more queries per second (both read and write), and the architecture must support these higher workloads seamlessly and efficiently. This blog attempts to explain what sharding is versus the pod architecture that some of our customers employ.

In our last blog post on this topic we covered the basics of the new REST  API available with Tungsten version 7.0.0. In this post, Part 2, we explore the REST API in more detail, including payloads and advanced functionality. The API provides a vast pool of capabilities, and here we barely scratch the surface of what can be accomplished.

When an application is a primary source of revenue for an organization, keeping Production operations going is critical. This blog discusses three things that can help prevent issues in Production. In fact, that’s why multiple environments exist - to make sure that the final act, delivered in Production, runs smoothly; read on to find out how to make sure your labor is not in vain!

At Continuent, we believe high-quality 24/7/365 Support is rare and invaluable. In today’s blog, I’d like to tell a short story about our support because it makes me really proud of my company. Our Support delivering effective solutions in an agile manner is just one of the many benefits of using Tungsten - and it’s cited as one of the main reasons our Customers stick with Continuent year after year.
