The latest from the MySQL community

Most of the users who work with distributions such as: centos, fedora, redhat, etc use yum as a package update/installer. Most of them know how to do “yum update [packagename]” (to update all or [certain packages]) or they do “yum install packagename” to install certain package(s). But yum can do so much more. Here are some options you may find useful:

Following command will search for the string you specified. Generally this will give you all of the packages which has specified string in title or description. Most of the time you will have to look through a lot of output to find what you are looking for.

yum search string

Probably one of the most important options for yum is provides/whatprovides. If you know what command you need, you can find out what package you have to install in order to have that command available to you.

yum provides (or whatprovides) command

This blog presents a new toolkit to assist in Dimensioning of MySQL Cluster.
The toolkit consists of two parts:

1. ndb_record_size
2. a spreadsheet to assist in calculating the amount of storage needed etc.
   

The ndb_record_size and the spreadsheets can be downloaded here.

ndb_record_size is a program that calculates the amount of storage (IndexMemory, DataMemory, Disk space (for disk data table)) that is needed for a particular table in a database. The program takes into account the storage overhead needed when calculating the record size.

There are two versions of the spreadsheet, one for MySQL Cluster 6.2, and one for MySQL Cluster 6.3. The main difference is that the spreadsheet for MySQL Cluster 6.3 takes into account compression of LCP and Backups if you chose to …

My ISP, which has a near monopolistic position in my country, has a support phone line. I called it yesterday, because my DSL was down. The usual routine goes: dial #1 for phone, #2 for data problems. I dial #2, and I get a recorded voice "all operators are busy. You can get support at our web site, www.xxx.it". I just called you because I can't connect, you dumb!

There is a huge movie theater nearby, which is convenient, but the queue at the ticket counter is uninspiring, especially during week-ends. So I check their online ticket sales. Can you believe this? They charge you an additional EUR 0.5 for online tickets. In my book, online services must be cheaper than manned ones, and this is why the airline and the books industries are moving their business online. Charging more for online tickets …

The last few month has been an interesting period for me. I used to work in the Database Technology Group, and as you may guess that group was affected by the acquisition of MySQL. The merge of the two teams are now complete, and we now all located in the Database Group.

During this merge it was natural to look at the staffing in the different projects, and I am extremely glad to see that the project I am working on get additional headcount.

I am therefore extremely exited over the fact that we have the following open positions in my team:

• Systems Technologist CT 3 in Menlo Park (CA)
• Memcached …

This release fixes bugs and changes the parser from SQL::Parser to DBIx::MyParsePP. This change was made in order to accommodate MySQL-specific deviations from Standard SQL. Unfortunately, this change also comes with the expense of a slow startup, but I think it is worth the trade-off. OmniMySQL can be downloaded here. CHANGELOG: 0.0.3 - 15 [...]

How To Set Up A Load-Balanced MySQL Cluster With MySQL 5.1

This tutorial is based on Falko Timme's tutorial for MySQL Cluster 5.0. It shows how to configure a MySQL 5.1 cluster with five nodes: 1 x management, 2 x storage nodes and 2 x balancer nodes. This cluster is load-balanced by an Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).
