Some MariaDB related news from the Red Hat front

This is a followup to my early post a month ago titled: MariaDB replaces MySQL in RHEL 7 (lots of stuff in the comments). It’s clear that MariaDB’s role is in Software Collections, which is new in RHEL.

Steven J. Vaughan-Nichols writes Red Hat will switch from Oracle MySQL to MariaDB, reports.

Sean Michael Kerner has a video (and writeup) with Denise Dumas, RHEL team leader, who talks about Software Collections, MariaDB, and how we’re all friendly …

On operating system upgrades and a packager’s nightmare

A fairy tale

Once upon a time I did an operating system upgrade, a minor one that should do no harm, but just get me up to date by fixing any bugs in the version I had been using. It seemed like a good idea.

All seemed to be fine. I use a package provided by an external vendor and not the one produced by the operating system provider as this vendor provides a newer version of the package and I need that. The vendor has to make his package fit in the os environment his package is built for and normally does a pretty good job.

I use automation to build my systems and when I built a new one some issues appeared. Related to the new version of the OS the provider had enhanced one of his packages and the installation pulled in new dependencies. The install of the external package I use then broke as it conflicted with the new dependency provided by the OS.  While a workaround is possible: uninstall …

Subject says its all, this is of course, very good news coming out of the Red Hat Summit. Looking forward to Red Hat Enterprise Linux 7. And of course, CentOS 7 and the other builds that follow. Thank you Red Hat!

Migrating MySQL 5.5.25a jiradb ERROR 2013 (HY000) on huge single db import

well, I incremented max_allowed_packet from 16M to 512M
anyway, I got the same error on the next clean import.
so decided to find a workaround.
so, how to get the data separated from the ddl statements:

# get the tables names into the insert statement, its better to have that in file for future usage
sed '/^INSERT INTO/!d;s/ VALUES.*$//' jiradb.20130118.sql | sort | uniq > tablas.como.nombres.txt

then how to get the data separated:

root@jiragg:[Fri Jan 18 15:26:33]:[/usr/local/BACKUP]$ cat make.inserts.sh
#!/bin/sh
# trim function thank to http://stackoverflow.com/questions/369758/how-to-trim-whitespace-from-bash-variable
# and http://codesnippets.joyent.com/posts/show/1816
trim() {
    local var=$1
    var="${var#"${var%%[![:space:]]*}"}"   # remove leading whitespace characters
    var="${var%"${var##*[![:space:]]}"}"   # remove trailing whitespace characters

}

Got open source cloud storage? Red Hat buys Gluster

Red Hat’s $136m acquisition of open source storage vendor Gluster marks Red Hat’s biggest buy since JBoss and starts the fourth quarter with a very intersting deal. The acquisition is definitely good for Red Hat since it bolsters its Cloud Forms IaaS and OpenShift PaaS technology and strategy with storage, which is often the starting point for enterprise and service provider cloud computing deployments. The acquisition also gives Red Hat another weapon in its fight against VMware, Microsoft and others, including OpenStack, of which Gluster is a member (more on that further down). The deal is also good for Gluster given the sizeable price Red Hat is paying for the provider of open source, software-based, scale-out storage for unstructured data and also as validation of both open source and software in today’s IT and cloud computing storage.

Open Query looking for new colleagues!

My colleagues and I are looking for extra talent – is that you?

What we do:help clients prevent problems (rather than being the fire department), we work on a subscription basis although we also do some ad-hoc consulting, and training. Apart from MySQL/MariaDB query and DBA work, we do quite a bit of system administration. Mainly Red Hat and Debian based distros, and expect to see replication and the MySQL-MMM multi-master system. You’d work from home, whereever it might be, so you will need to be self-motivating (but we do keep in touch online).

What we’re not: a full-time employer. With us, you make a life rather than a living. Everybody is contracted part-time. You can make enough to live comfortably, but that has nothing to do with hours. If you’re stressed about not filling all hours in your week with work-work-work, we’re not the company for you… there’s more to life than …

Until now, MariaDB 5.2 was lacking a yum repository for easy installs and upgrades. It is now available, thanks to OurDelta.

Just follow our very simple installation instructions.
