This post is part two of MySQL Replication with Global Transaction Identifiers – Step-by-Step Install and Addition of Slaves. In this post, I will be showing you how to use the MySQL Utility Script mysqlreplicate to create a new replication slave off a master database.

This is also the fourth in a series that I will be doing on MySQL Workbench Utilities – Administer MySQL with Python Scripts. You may want to read the first half of …

There are many good things in the upcoming MySQL 5.6 release. One thing that caught my eye early on was the ability to start the server with InnoDB set to a read only mode.

A few months ago Todd Farmer wrote about this ability from the perspective of setting up an instance on read-only media (InnoDB now works with read-only media). And I encourage you to read that post first.
I decided to test this from a data warehouse perspective (as Sunny Bains points out in a comment to Todd's post). I used machines I have available: 1 OL6 desktop running 5.6.9 and 1 MacBook Pro running 10.8.

First thing to try was adding the innodb_read_only parameter to the config file on an instance I already had running on the Linux box. My setting:

[mysqld]
user = mysql
port = 5602

The MySQL Installer is an easy way to install and maintain your MySQL installations on Microsoft Windows.

It comes not only with the database server and documentation, but also with the underrated MySQL Workbench, and various connectors and support utilities such as MySQL for Excel. Modifying the installed products or uninstalling them is also fairly straightforward: 

 Start -> All Programs -> MySQL -> MySQL Installer -> MySQL Installer

This launches the Maintenance window of the Installer GUI, and gives you the options:

• Add/Modify Products and Features
• Check for Updates
• Remove MySQL Products. …

Before moving to Couchbase and working with NoSQL technology I had for years been a MySQL user. Making that leap from MySQL to NoSQL requires a number of changes, not least of which to the way you structure your data and then query it. 

I’ve tried to distil the first part of that process down into a simpler form and steps in a new blog post oat the Couchbase blog http://blog.couchbase.com/how-move-mysql-couchbase-server-20-part-1

openSUSE 12.3 is getting closer and closer and probably one of the last changes I pushed for MySQL was switching the default MySQL implementation. So in openSUSE 12.3 we will have MariaDB as a default.

If you are following what is going on in openSUSE in regards to MySQL, you probably already know, that we started shipping MariaDB together with openSUSE starting with version 11.3 back in 2010. It is now almost three years since we started providing it. There were some little issues on the way to resolve all conflicts and to make everything work nicely together. But I believe we polished everything and smoothed all rough edges. And now everything is working nice and fine, so it’s time to change something, isn’t it? So let’s take a look of …

CSO Online writes about a rather sad list of security breaches at http://www.csoonline.com/article/721151/fatal-half-measures-in-incident-response, and the half-hearted approach companies take in dealing with the security on their networks and websites.

What I find most embarrassing is that it appears (judging by the actions) that many companies have their lawyers do some kind of borked risk assessment , and decide that they can just leave things as-is and yell foul when there’s a breach. After all, particularly in the US prosecutors are very heavy handed with breaches, even when the company has been totally negligent. That’s weird, because an insurance company wouldn’t pay out for a break-in when you’ve left your front door wide open! The problem is of course that the damage will have been done, …

Installing MySQL is a simple process. It is very common on a modern Windows machine to install in under three minutes. The Windows Installer Team have really increased the speed in the last few releases. But what if you are running Linux?

For the very fussy who want everything tailored ‘just so’, download the source code and configure exactly what you want. Don’t need Serbian character sets, different collations, or some storage engines you never use? Then read up on Installing MySQL from Source. With a bit of time and fuss, you can have a minimalist server that contains only the components you need. This is not recommended unless you know you can lock down the system and never, ever need to ad more components on the fly.

Next comes the MySQL Binaries. Untar/Zip the file from Dev.MySQl.Com, point your config files to the …
