Tungsten Clustering 6.0 and Tungsten Replicator 6.0 are now available!

Continuent is very pleased and excited to announce that the new Tungsten Clustering 6.0 and Tungsten Replicator 6.0 are now available for download by our customers. The 6.0 release is the culmination of over a years work within our clustering product in order to improve the functionality and manageability of what we now call our ‘Multimaster Clustering’ solution. This is the replacement for what we called the multi-site, multi-master (MSMM) clustering functionality in earlier releases. The multimaster clustering allows for multiple clusters, in multiple locations, to be linked together into a single composite cluster. Because it’s a composite cluster, you gain all of the functionality that’s already available in a cluster, such as:

  • High availability
  • Failover
  • Automated recovery
  • Read-write split
  • Maintenance without downtime

But it’s now applied to the …

Percona XtraDB Cluster and SELinux: Getting It To Work

In this blog post, I’ll look at how to make Percona XtraDB Cluster and SELinux work when used together.

Recently, I encountered an issue with Percona XtraDB Cluster startup. We tried to setup a three-node cluster using Percona XtraDB Cluster with a Vagrant CentOS box, but somehow node2 was not starting. I did not get enough information to debug the issue in the donor/joiner error log. I got only the following error message:

MySQL vs. MariaDB: Reality Check

In this blog, we’ll provide a comparison between MySQL vs. MariaDB (including Percona Server for MySQL).

Introduction

The goal of this blog post is to evaluate, at a higher level, MySQL, MariaDB and Percona Server for MySQL side-by-side to better inform the decision making process. It is largely an unofficial response to published comments from the MariaDB Corporation.

It is worth noting that Percona Server for MySQL is a drop-in compatible branch of MySQL, where Percona contributes as much as possible upstream. MariaDB Server, on the other hand, is a fork of MySQL 5.5. They cherry-picked MySQL features, and don’t guarantee …
