Oracle have just announced that MySQL Cluster Manager 1.2 is Generally Available. For anyone not familiar with MySQL Cluster Manager – it’s a command-line management tool that makes it simpler and safer to manage your MySQL Cluster deployment – use it to create, configure, start, stop, upgrade…. your cluster.

So what has changed since MCM 1.1 was released?

The first thing is that a lot of work has happened under the covers and it’s now faster, more robust and

On-line add-node with MCM; a more complex example
Employee +4 Vote Up -0Vote Down

I’ve previously provided an example of using MySQL Cluster Manager to add nodes to a running MySQL Cluster deployment but I’ve since received a number of questions around how to do this in more complex circumstances (for example when ending up with more than 1 MySQL Server on a single host where each mysqld process should use a different port). The purpose of this post is to work through one of these more complex scenarios.

The starting point is an

MySQL Cluster Manager 1.1.2 is now available to download and try from Oracle E-Delivery (select “MySQL Database” as the product pack).

This post aims to show that

Managing Database Clusters - A Whole Lot Simpler
Employee_Team +3 Vote Up -0Vote Down
Clustered computing brings with it many benefits: high performance, high availability, scalable infrastructure, etc.  But it also brings with it more complexity.

Why ?  Well, by its very nature, there are more "moving parts" to monitor and manage (from physical, virtual and logical hosts) to fault detection and failover software to redundant networking components - the list goes on.  And a cluster that isn't effectively provisioned and managed will cause more downtime than the standalone systems it is designed to improve upon.  Not so great....

When it comes to the database industry, analysts already estimate that 50% of a typical database's Total Cost of Ownership is attributable to staffing and downtime costs.  These costs will only increase if a database cluster is to hard to properly administer.

MySQL Cluster Manager 1.1 available!
Employee +5 Vote Up -0Vote Down

As the title of this post suggests, MySQL Cluster Manager 1.1 is now available – but this actually has a double meaning:

  • MySQL Cluster Manager 1.1 is GA (I’ll explain below the major improvements over 1.0)
  • Everyone is now able to download and try it (without first having to purchase a license)!
  • This software is only available through commercial licenses (i.e. not GPL like the rest of Cluster) and until recently there was no way for anyone to try it out unless they had already bought MySQL Cluster CGE; this changed on Monday when the MySQL software became available through Oracle’s E-Delivery
