Does MySQL replication support Oracle11g Database as target? Or we have to use Goldengate for that?
Thanks.

Read the original article at How to hire a developer that doesn’t suck

Strip by Randall Munroe; xkcd.com

First things first. This is not meant to be a beef against developers. But let’s not ignore the elephant in the living room that is the divide between brilliant code writers and the risk averse operations team.

It is almost by default that developers are disruptive with their creative coding while the guys in operations, those who deploy the code, constantly cross their fingers in the hope that application changes won’t tilt the machine. And when you’re woken up at 4am to deal with an outage or your sluggish site is costing millions in losses, the blame game and finger-pointing starts.

If you manage a startup …

Read the original article at Book review – Trust Agents by Chris Brogan & Julien Smith

Stumbling onto 800-CEO-Read, and their top books feature, I found Brogan and Smith's work.  Brogan's blog intrigued me enough so I walked down to the Strand here in NYC to pick up a copy.

What I found was an excellent introduction to the nebulous world of social media marketing, where you find all sorts of advice and suggestions on how to engage your target audience.  If you're feeling like an ignoramus on matters of social media, Trust Agents is a great place to start and will give you ideas of how to 'humanize' your digital connections.

The authors illustrate the Trust Agent idea with Comcast Cares for example and how they engaged customers, and what …

I'll be doing the keynote at Cloud Tech Day here in Stockholm on tuesday. I'll be speaking a bit about what Recorded Future is up to, about Clouds at Amazon and what it is like, about databases, like MySQL and MongoDB, in the Clouds and about Big Data in the Cloud! Really big data in Mongo, in MySQL and the lot.

As usual, I will express my opinions in no uncertain terms. What works? What doesn't work? What really should work, but which doesn't! What is considered new and waay cool but what is really some old technology that didn't use to work and has little chance of working now. And stuff like that, you know what it's like and maybe you even know what I am like :-)

Hope to see you on tuesday

I will be speaking in the MySQL track of the UK Oracle User Group conference on 5th December in Birmingham UK. The title of the session is "Building Highly Available and Scalable, Real Time Services with MySQL Cluster" - full details here.

I'm not a regular conference attendee, never mind speaker. However I'm looking forward to meeting current and potential MySQL users, and also attending some of the talks in the MySQL and other tracks. Maybe I can learn something about RAC, or Exadata?

If you are attending and want to talk about MySQL or MySQL Cluster then please track me down and say hello.

Note that this is the first picture I have included in 3 years of posts - maybe …

Thanksgiving is here and the circular chain of thankfulness is going on. Clients are thankful that they have applications, applications are thankful to their databases, database are thankful to their DBAs, and DBAs are thankful to clients. And they all are thankful that there is weekly Log Buffer Edition, of which the latest is Log [...]

It is no secret that bugs related to multithreading–deadlocks, data races, starvations etc–have a big impact on application’s stability and are at the same time hard to find due to their nondeterministic nature.  Any tool that makes finding such bugs easier, preferably before anybody is aware of their existence, is very welcome.

Enter the Helgrind tool of the Valgrind dynamic analyzer suite. Now, Valgrind does not need much introduction, especially to the MySQL server developers. The Valgrind Memcheck tool, which is synonymous with Valgrind itself, is relatively widely used for the MySQL server development: there is support for it in the MySQL Test Framework, DBQP, and the server source is properly annotated to get the most out of Memcheck. Not …

MySQL Workbench 5.2.36 is now out and brings a lot of improvements across the board, with special focus on the Query Editor. We’ll cover some of that here:

Redesigned Query Editor

• • The log of executed commands and server responses is now always visible while resultset grids and the query editor can be resized according to your needs. Resultsets are also grouped in the same tab as the query editor that generated them.
  • SELECT queries are now analyzed as in the old MySQL Query Browser tool and, if possible, its resultset can be edited in the grid. If the resultset cannot be edited, you can place the mouse over the ReadOnly label and view the reason.

• Improved snippets manager and editor, allows having snippets list always at hand, while editing can be done without disrupting work on the main query area.

The MySQL explain plan is a great tool to help developers and database administrators to improve the performance of specific queries happening against a database. It is very easy to use, but its output can be confusing, so I thought I'd show a very simple example.

Let's begin by looking at a table called recipes

mysql> desc recipes;

| Field       | Type         | Null | Key | Default | Extra          |
