Itchy Ninja Software is pleased to announce the release of Analyst for MySQL v1.1. Revolutionize the way you work and administrate MySQL, MariaDB, Galera, and Percona XtraDB installations.

Make More Efficient Use of Your Time

Gathering all of the metrics to diagnose a database installation is a very time consuming process, and many simply do not have the experience to know where to begin. With Analyst for MySQL, you will be able to get your hands on hundreds of metrics within moments. It really takes all of the guesswork, as well as tedious long sessions of writing queries out of managing a MySQL database server.

Cross-Platform

Not only can you run the program on Windows, Mac, or Linux, you can also generate server reports from each of those platforms as well! No need to install anything on the server at any time. All diagnostics are run from your laptop or desktop machine. The …

A much requested feature has made it to MySQL 5.7.6: Global Transaction Identifiers (GTIDs) can now be enabled online, without stopping writes, synchronizing servers, or restarting servers.

We introduced GTIDs in MySQL 5.6.6. GTIDs allow, among other things, seamless fail-over after a master has crashed. This enables highly available applications, since service can continue without interruption even if the master crashes. For new deployments, you could easily enable GTIDs right away – just set gtid-mode=ON in the configuration files. For deployments that accept a certain amount of downtime, you could switch from off to on too. However, for big deployments with strict limitations on downtime, this was more problematic, since you had to stop updates, sync all servers, and restart all servers simultaneously with GTIDs enabled, and this would lead to several minutes of downtime.

In MySQL 5.7.6, we have now made it possible to enable …

More Awesome Replication Features in 5.7.6

It is time to celebrate again. The latest MySQL server development milestone (MySQL 5.7.6) was just released, and let me tell you, it is full of great replication enhancements. These new improvements cover many areas, ranging from performance to flexibility and easier deployment. Let me highlight some of them, and give you a brief summary of what they are.

Multi-source Replication

A MySQL 5.7.6 slave/server can now connect to multiple MySQL masters.

After a long development period, two labs releases, handling feedback from community, and a lot of internal (and external testing as well – thank you!), the multi-source replication feature was finally pushed into MySQL 5.7. This is a major milestone for replication itself. The feature allows a single MySQL server to aggregate …

We are very happy to introduce a new MySQL utility named "mysqlslavetrx", which allows users to easily skip multiple transactions on multiple servers in a single step. This utility is one of three new utilities included in MySQL Utilities release-1.6.1 Alpha. The other utilities are "mysqlbinlogpurge" and "mysqlbinlogrotate", which can be used to purge and rotate binary logs.

The mysqlslavetrx utility allows you to skip multiple transactions on several slaves. More precisely, it injects empty transactions for the specified Global Transaction Identifier (GTID) set and list of target slaves. Skipping transactions can be useful to quickly recover from erroneous situations that can occur during the replication process, or to handle errant transactions. Check out the following blog posts for more details about concrete situations where you might need to inject empty transactions:
