Red Hat Enterprise Linux 3 aka RHEL 3 was a very popular Linux distribution during the last 2 years. However, it is not applicable by now. It came with MySQL 3.23.58 which is already obsoleted by some web applications due to lacking of unicode support and incompatibility to later version.

Yesterday was the time to remember for me. My friend asked me to help upgrading MySQL 3.23.58 in RHEL3 to newer version because he was unable to install even Joomla! and phpBB. It seems the latest version of these applications has been already dropped support for MySQL 3.x. He didn't want to upgrade the whole distribution because it supposed to take longer time to backup and restore data. That's why I have to do some painful thing. One thing to concern was Ensim. He has not been familiar to Linux including RHEL so he bought an Ensim license to manage the site just for himselves. So I have to make it work just like before.

If you are using flashplugin-nonfree in Ubuntu Dapper from backports like me, you might see some error according to post-installation script failed.

I recommend all you to upgrade as soon as possible because there are multiple vulnerabilities in current versions.

I found something weird after trying to upgrade some RPM packages using YUM. The problem was hang by message as follow.

Setting up package sacks

It happened when I was running yum update since the repository had changed from CentOS 4.3 to CentOS 4.4. It seems this was a popular problem because I found a thread at CentOS board. The solution is also available to guide me through the step. Not exact one but useful.

Today I would like to extract a file in an RPM because I accidentally made some changes to a configuration file. Actually, it's not me to do that directly. rpm changed my modified file during upgrade so I want to recover that file from the original RPM. Well, I'm not dare enough to reinstall that RPM. That's why I wanted to extract only one file.

Sorry for so long delay. It's all my fault since I am very busy due to my work. Anyway, I have been trying to upgrade core engine from BitTorrent 4.4.0 to BitTorrent 4.20.9. After getting the note, I decided to publish my unfinished work.

svn co https://svn.sourceforge.net/svnroot/btqueue/branches/BitTorrent-4.20.9 btqueue

Don't expect too much. It is in very early stage and unusable in all case. It could just start the program and exit properly.

I have seen the first problem in using [NPACI Rocks 4.2][]. The symptom is I was unable to submit just a basic job to [SGE][] because of following error in standard error file.

MANTYPE: Undefined variable
