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
  • Faster Cluster rolling restarts – data nodes from different node groups will be restarted in parallel (still avoids an outage but cuts the end-to-end restart time)
  • 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.…
