On-line add-node with MCM; a more complex example

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).…

MySQL Scaling breakfast seminar – London, April 25th

I’ll be presenting on/demoing MySQL Cluster 7.2 at this free breakfast seminar in Oracle’s London office on 25th April – starting with coffee at 9:00 and ending with lunch at 13:00 (quite a generous take on “breakfast”!).

MySQL Cluster Manager 1.1.4 Released – includes support for MySQL Cluster 7.2

MySQL Cluster Manager 1.1. is now available to download and try from Oracle E-Delivery (select “MySQL Database” as the product pack).

There’s lots of good stuff gone in under the covers as part of this release, with some of the highlights being:

  • Support for MySQL Cluster 7.2
  • Configuration of MySQL Server parameters
  • Verbose option added to commands for extra info on what’s going on

  • Robustness enhancements to the configurator – especially important when managing large Clusters
  • Bug fixes (well we always need to include that one)

More details on the changes can be found in the MySQL Cluster Manager documentation.…
