You can use all these utilities either standalone or with MySQL Workbench.

MySQL Enterprise Backup: parallel config & backup n restore results.
Employee +0 Vote Up -0Vote Down

In this post I go into some performance metrics and time spent on using MySQL Enterprise Backup instead of mysqldump, and seeing how far I could go with some parallel configuration.

Setup:

It’s on an old laptop:

–Ubuntu 12.04 LTS, 32bit Intel Pentium M 1.86Ghz, 2Gb –Source disk:  internal 80Gb ATA ST9808211A –Destination:  external 1Tb SAMSUNG HD103SI –MySQL Enterprise Edition 5.6.15 –MySQL Enterprise Backup 3.9.0 –Employees sample database duplicated via MySQL Utilities 1.3.6 (on Win7 PC) to generate a ~5Gb MySQL Server. And to simulate data size, I used the MySQL Utilities:
mysqldbcopy --source=root:pass@host:3356 --destination=root:pass@host:3356 employees:employees1 \

MySQL Replication: Self-Healing Recovery with GTIDs and MySQL Utilities
Employee_Team +2 Vote Up -0Vote Down

MySQL 5.6 includes a host of enhancements to replication (http://www.mysql.com/products/enterprise/replication.html), enabling DevOps teams to reliably scale-out their MySQL infrastructure across commodity hardware, on-premise or in the cloud.

One of the most significant enhancements is the introduction of Global Transaction Identifiers (GTIDs) where the primary development motivation was:

- enabling seamless failover or switchover from a replication master to slave

- promoting that slave to the new master

- without manual intervention and with minimal service disruption.

MySQL Utilities: The New .frm Reader Utility
Employee +7 Vote Up -0Vote Down
Have you ever wondered what was in those .frm files littered throughout your data directory? Better still, have you encountered a situation where your data is either missing (was deleted) or damaged and all you have is the .frm files but don't know the structure of the table? Well, wonder no more!

The MySQL Utilities Team is pleased to announce the newest utility - the .frm reader (mysqlfrm). This utility is designed to read .frm files and produce a facsimile of the CREATE statement for the table or view.

That's Impossible! How Can That Work?


It works by making a copy of the .frm file(s) and launching a new, read-only instance of your existing server. The server need not be running but you are required to provide an open port for the new instance with the --port option.

The utility will launch the cloned server without

Introducing MySQL Utilities release-1.3.0
Employee +5 Vote Up -0Vote Down
The MySQL Utilities Team is pleased to announce a major advancement of MySQL Utilities. It is now available as a separate download!

That's right. If you want to use MySQL Utilities without installing MySQL Workbench, you can do that now.

The Utilities release-1.3.0 has been built for Windows Installer, RPM archive, and .tar/.zip. We have also made downloads for source only if you want to use Utilities to develop your own utilities or install the product in custom location. We plan to add other repositories in the future.

Is that it? Well, not quite. We have also included a new utility - the .frm Reader. See the blog, "New Utility: .frm Reader" for more information.

If you'd like to try out the new download, visit the MySQL Workbench download page:
