MyTOP is a console-based (non-gui) tool for monitoring the threads and overall performance of a MySQL created by Jeremy Zawodny.
For months now I have been adding updates to mytop. When I started using version 1.6 it worked but didn’t return some data fields. After fixing these bugs I began to ideas for improvements. Here is a quick list of what I have done.
- New ‘!’ command to force fix replication errors.
- Display rows sorted per second.
- Added new ‘Cmd’ column to display the state of the query along with the statement.
- New ‘M’ command to change the [Mode] to ‘status’. This was in the code but covered up by another command.
If you find any bugs or would like to see your own updates added …
[Read more]MySQL is frequently referred to as a database for Web applications. Partially it is really so, because MySQL became popular owing to its simplicity, high speed, and bounding with PHP. Developers of small Web projects often choose MySQL as a back end of their sites. Does this mean that MySQL can be used only for small databases? Not at all. There are lots of databases size of data in which is measured in gigabytes. Besides MySQL servers are frequently clustered to increase their performance. When a DBAs work with large amounts of data, they frequently have to make backup copies correctly and effectively, i. e. to export MySQL databases to SQL (or MySQL backup). It is extremely important to import MySQL database from SQL correctly is when restoring a corrupted database and when migrating a database from one server to another.
What should be taken into account when exporting a large MySQL …
[Read more]In my previous article I had created linked server, to access and query a database. However, it is just the basic step to try and bring two different RDBMS systems linked together.
In this article I will discuss about creating a SSIS package to transfer data from MS SQL Server 2008 to MySQL 5.5
Prerequisite:
___________________________________________________
SQL Server Business Intelligence Development Studio
MySQL Connector Net 5.2.7
You can download this package from http://www.mysql.com/downloads/connector/net/
Connector/Net is a fully-managed ADO.NET driver for MySQL.
MySQL Connector/ODBC 5.1 (Which is already installed, in our previous article)

The history and accomplishments attributed to VistA, the
Veterans
Administration's core administrative software, mark it as one of
the
most impressive software projects in history. Still, lots of
smart
people in the health care field deprecate VistA and cast doubt
that it
could ever be widely adopted. Having spent some time with people
on
both sides, I'll look at their arguments in this blog, and
then
summarize other talks I heard today at the

Convention
health care track.
Yesterday, as

described in my previous blog, we heard an overview of trends
in
health care and its open source side in particular. Two open

free software projects offering electronic health records
were
presented, …
Sometimes I find Google annoying. Don’t get me wrong, I am not one of the many Google haters out there. They have done amazing things and especially since they have released WebM as Open Source and royalty free video format, they have earned a bonus in my attitude towards them. And even though Google Chrome is not my personal favorite, I have to admit that Chrome has brought a great momentum into the development of web browsers (and therefor the WWW as a whole) which users of any browser benefit from. Last but not least, I use a lot of Google’s services and they do their job quite well. So all in all, Google’s record from my point of view is pretty good.
But one thing really sucks. I use an English operating system. I use an English Firefox (locale en-US). All the language preferences in the Google profiles of my …

MySQL Workbench is a great tool for developers to map out and
visualise databases. What many people know is that it’s also a
great way to make upgrading and writing upgrade scripts for your
components really painless too.
Let’s say you created a small component that became popular over
night. Tens of thousands of downloads from on the Joomla
Extensions Directory. So you get inspired and put some more work
into improving and bugfixing this component even more, and while
doing that you change and add on to the database schema.
Now you need to create and distribute an update script with the next version of your component, and MySQL Workbench makes creating this update script really easy. Here is what you need to do:
Install MySQL Workbench
I’ll not help you with this. Just go to the MySQL Workbench homepage and follow the instructions from there. …

A new release of the PrimeBase Media Streaming daemon is now
available for download at
http://www.blobstreaming.org .
This release doesn't contain any major new features just some bug
fixes and a lot of house keeping changes.
If you look at the download section on http://www.blobstreaming.org you will see that
there are now more packages that can be downloaded. I have
separated out different client side components from the PBMS
project and created separate launchPad projects for each one. You
can see them listed in the "Related Links" side panel to the
right of this post.
- The "PBMS Client Library" facilitates communication with the PBMS daemon. This library is independent of the PBMS daemon's host server and can be used to communicate with a PBMS daemon hosted by …
