Yesterday I learnt an important lesson about an important difference between NoSQL and MySQL, at least when it comes to the marketing and hype.

I saw a tweet from around marketing of one of NoSQL leaders:

Most people apparently would just conclude from the tweet's text, however I actually clicked the link, and couldn't believe eyes:

I guess that in NoSQL, when it comes to the integrity of data as well as hype - it is eventually consistent...

While I posted how to install Toad for MySQL Freeware five years ago, I’m always surprised how few people know about it there and consistently updated and improved. You can download Toad for MySQL Freeware or Toad Freeware for Oracle, SQL Server, Sybase, or IBM DB2 at this web site.

You can also download Toad Data Modeler Freeware Edition. Just two notes, while Toad for Oracle Freeware is an MSI file, Toad for MySQL Freeware is a zip file and limited to only a Windows …

MySQL SystemQA: MySQL Fabric server farm Setup and Testing overview

MySQL Fabric is an open-source solution released by the MySQL Engineering team at Oracle. 
It is an extensible and easy to use system for managing a MySQL deployment for Sharding  
and High-availability.

High availability is generally used to describe the ability of a system to continue operating 
and provide resources to the application when a failure occurs in one or more of the 
following categories in a fault domain: hardware, software, or application.

With high availability feature, MySQL fabric manages several servers in different groups
using replication topology. At any point of failure it creates servers available to do the regular 
activities.

To test similar functionalities, we have designed a setup in JET framework which will handle multiple 
servers in multiple machines.

What we did?

We have started with a fabric setup class in JET framework, which …

MySQL 5.6 introduced a new feature called GTID (Global Transaction IDentifier) support in Replication. For every transaction that is committed on to the server, a GTID of the format :

server_uuid:transaction_id is written into the master's binary log.

This offers the following advantages:

• Very helpful to set up a slave and create a replication setup.

• User need not worry about fetching the master's binlog filename and position in the “CHANGE MASTER TO” command which is used to synchronise the slave with the master.

• Applying GTIDs on slaves ensures consistency – since GTIDs are unique, it cannot be applied more than once on the server.

For a gtid enabled server, the following properties need to be set on both Master and Slave configuration files as shown below in …

MySQL SystemQA: MySQL Fabric Setup using ndb Cluster

MySQL Fabric is an open-source solution released by the MySQL Engineering team at Oracle. It is 
an extensible and easy to use system for managing a MySQL deployment for Sharding  and
High-availability.

To ensure/provide resilience to failures, MySQL Fabric manages servers in groups and deploy 
High Availability. MySQL Fabric also supports Sharding, which is used to scale out a large 
databases. Sharding setup handles the increasing demand for read loads and also handles the 
increasing write loads. The database/table are shared across different servers, where each shard
contain a fragment of the data.



A Fabric node is Fabric Process + State Store (which is a MySQL Server).As MySQL Fabric 
manages such a valuable information for server farms and scaling of database, using single 
machine to handle the MySQL Fabric node is not a good solution. Thus we need to come up 
with a solution that …

MySQL for Visual Studio 1.2.0 was just released the last week. In this post we will make a quick introduction on what's coming up in this new version. 

MySQL for Visual Studio is a product including all of the Visual Studio integration previously available as part of Connector/Net. The 1.2.0 version is an alpha release of this product that intents to introduce users to the new features in this version.

One thing that gets tedious in the IT community and Oracle community is the penchant for Windows only solutions. While Microsoft does an excellent job in certain domains, I remain a loyal Apple customer. By the way, you can install Oracle Client software on Mac OS X and run SQL Developer against any Oracle Database server. You can even run MySQL Workbench and MySQL server natively on the Mac OS X platform, which creates a robust development platform and gives you more testing options with the MySQL monitor (the client software).

Notwithstanding, some Windows users appear to malign Apple and the Mac OS X on compatibility, but they don’t understand that it’s a derivative of the Research Unix, through BSD (Berkeley Software …
