The Question Recently, a customer asked us:

How would we manually move the relay role from a failing node to a slave in a Composite Tungsten Cluster passive site?

The Answer The Long and the Short of It

There are two ways to handle this procedure manually when the usual switch command fails to work as expected. One is short and reasonably automated, and the other is much more detailed and manual.

Of course, the usual procedure is to just issue the switch command in the passive cluster:

use west
set policy maintenance
switch
set policy automatic

The below article describes what to do when the switch command does not move the relay role to another node.

SHORT

Below is the list of cctrl commands that would be run for the basic, short version, which (aside from handling policy changes) is really only three …

Overview The Skinny

Tungsten Clustering provides high availability, disaster recovery, and a host of other benefits for MySQL / MariaDB / Percona Server databases. In this blog post we will explore some of the shell aliases I use every day to administer various Tungsten Clusters.

Shell Aliases: A Quick Review Quick and Easy

A shell alias is simply a way to create a shortcut for frequently-used command sequences.

For example, I like to shorten the command clear to cls, i.e.

shell> alias cls=clear
shell> cls

If you create an alias on the fly it will be lost when the shell exits.

To save aliases so they are available to all shell sessions, update your shell’s profile or rc script.

For example, add the below line to the bottom of …

Like I stated in my previous article - MySQL InnoDB Cluster - Recovering and provisioning with mysqldump :
"As the administrator of a cluster, among others tasks, you should be able to restore failed nodes and to add (or remove) new nodes".
Well, I still agree with myself :)
MySQL customers using a Commercial Edition have access to MySQL Enterprise Backup (MEB) which provide enterprise-grade physical backup and recovery for MySQL.
MEB delivers hot, online, non-blocking backups on multiple platforms including Linux, Windows, Mac & Solaris.

The post MySQL InnoDB Cluster - Recovering and provisioning with MySQL Enterprise Backup first appeared on dasini.net - Diary of a MySQL expert.

As the administrator of a cluster, among other tasks, you should be able to restore failed nodes and grow (or shrink) your cluster by adding (or removing) new nodes.
In MySQL, as a backup tool (and if your amount of data is not too big), you can use mysqldump a client utility that performs logical backups.
The results are SQL statements that reproduce the original schema objects and data.
For substantial amounts of data however, a physical backup solution such as MySQL Enterprise Backup is faster, particularly for the restore operation.
But this is the topic of my next blog post :)

Are you looking to get started with the world’s most popular open-source database, and wondering how you should setup your MySQL hosting? So many default to Amazon RDS, when MySQL performs exceptionally well on Azure Cloud. While Microsoft Azure does offer a managed solution, Azure Database, the solution has some major limitations you should know about before migrating your MySQL deployments. In this post, we outline the best way to host MySQL on Azure, including managed solutions, instance types, high availability replication, backup, and disk types to use to optimize your cloud database performance.
