Welcome to this week’s Planets9s, covering all the latest resources and technologies we create around automation and management of open source database infrastructures.

In this post, I’ll discuss how database support is good for your enterprise.

Years ago when I worked for the MySQL Support organization at the original MySQL AB, we spoke about MySQL Support as insurance and focused on a value proposition similar to that of car insurance. You must purchase car insurance before the incident happens, or insurance won’t cover the damage. In fact, most places around the world require automobile insurance. Similarly, many organizations that leverage production-use technology have their own “insurance” by means of 24/7 support.

In my opinion, this is a very one-sided view that does not capture the full value (and ROI) that a database support contract with Percona provides. With a Percona support contract, you are assured that your database environment …

Companies know they need a database administrator, but they probably don’t have any clue about what they actually do. The primary duty for a MySQL server DBA is not waking up in a panic because the phone rang so much it fell off the nightstand during their on-call nights. Outside of that situation, a DBA’s function typically revolves around making sure the data is safe, sound and in one piece when the business needs it. Organizations use different database setups to try to confuse new database administrators, even though they typically involve the same day-to-day tasks.

Monitoring and Optimization

When database administrators get to work, they creep quietly into the building in an attempt to avoid end users chasing them down with not-so-priority problems. After a sufficient amount of caffeine, they fire up their monitoring programs to see whether the …

Two weeks after the big annual event in San Francisco, Oracle Open World 2016 , September 18-22, there will be another MySQL focused event in Europe: Percona Live Amsterdam, October 3-5.

The MySQL Engineering Team and Community Team will be present. We have submitted a list of very interesting talks, mostly related to the upcoming new major release of MySQL.

In an effort to involve the larger community in the talks selections, PLAM’s organization implemented a community voting process for the previous edition. If this will be again the case and if you are interested by our sessions, don’t hesitate to vote, if the vote is available, for the sessions you would like to see or just tweet about them using #perconalive …

From September 18–22, 2016 in San Francisco will be held the 2016’s edition of Oracle Open World. The MySQL Team will be well represented with more than 20 sessions related to all the new stuff we released for 5.7 and many other amazing things for 8.0.

I have the honor to present you a tutorial on one of the most wanted feature: Group Replication.

MySQL Group Replication is a new plugin that ensures virtual synchronous updates on any member in a group of MySQL servers, with conflict handling and failure detection. Distributed recovery is also in the package to ease the process of adding new servers to your server group.

This tutorial will be full hands-on. Matt Lord and myself will guide on the process of upgrading your asynchronous replication architecture to the new multi-master group replication !

Most people know that you can use SHOW SLAVE STATUS to verify if a slave is running in MySQL. Most people also know that you need to check both Slave_IO_Running and Slave_SQL_Running.

View the code on Gist.

A few years ago, I responded to a question on dba.stackexchange.com on how to verify if a slave is running outside of SHOW SLAVE STATUS.

Prior to MySQL 5.7, you could get this information from SHOW GLOBAL STATUS:
