MySQL High Availability with Oracle Clusterware
Employee +1 Vote Up -0Vote Down

MySQL has an extensive range of high-availability solutions (http://www.mysql.com/products/enterprise/high_availability.html) to suit many different use cases and deployment needs.  This list spans from the time-tested – yet continuously-improved – MySQL replication to the just-released MySQL Fabric, giving users many certified solutions for highly available MySQL deployments.  The list is growing yet again, with Oracle Clusterware adding support for MySQL.

Oracle’s Clusterware product is the foundation for the Oracle RAC, and has been battle-tested for high availability support for Oracle database, as well as other Oracle applications.  This technology is now available as part of the MySQL Enterprise subscription, and – like all Oracle commercial products – is

Deep Dive into GTIDs and MySQL 5.6 - What, Why and How
Employee_Team +6 Vote Up -0Vote Down

Global Transaction Identifiers (GTIDs) are one of the key replication enhancements in MySQL 5.6. GTIDs make it simple to track and compare replication across a master - slave topology. This enables:

- Much simpler recovery from failures of the master,

- Introduces great flexibility in the provisioning and on-going management of multi-tier or ring (circular) replication topologies.

A new on-demand MySQL 5.6 GTID webinar (http://www.mysql.com/news-and-events/web-seminars/mysql-replication-simplifying-scaling-and-ha-with-gtids/) delivered by the replication engineering team is now available, providing deep insight into the design and implementation of GTIDs, and how they enable users to simplify MySQL scaling and HA. The webinar covers:

New Replication, Optimizer and High Availability features in MySQL 5.6.5!
Employee_Team +4 Vote Up -0Vote Down

As the Product Manager for the MySQL database it is always great to announce when the MySQL Engineering team delivers another great product release.  As a field DBA and developer it is even better when that release contains improvements and innovation that I know will help those currently using MySQL for apps that range from modest intranet sites to the most highly trafficked web sites on the web.  That said, it is my pleasure to take my hat off to MySQL Engineering for today's release of the MySQL 5.6.5 Development Milestone Release ("DMR"). The new highlighted features in MySQL 5.6.5 are discussed here:

New Self-Healing Replication Clusters

    Raid is obsolete
    +0 Vote Up -0Vote Down

    In a lot of environments.

    Peter gives a nice overview why you don't always need to invest in big fat redundant hardware.

    We've tackled the topic last year already ..

    Now I often get weird looks when I dare to mention that Raid is obsolete ..people fail to hear the "in a lot of environments"

    Obviously the catch is in the second part, you won't be doing this for your small shop around the corner with just one machine. You'll only be doing this in an environment where you can work with a redundant array of inexpensive disks. Not with a server that has to sit in a remote and isolated location.

    Next to that there are situations where you will be using raid, but not for redundancy, but for disk throughput.
