So, after installing Workbench 6.0.7 on my pc, and playing around with the MySQL Utilities that are included, I thought I’d do similar to what others have done (Thanks Tony D.) and share my experience on how I’ve used them. If you haven’t installed Workbench before, you might want to check your platform first: http://www.mysql.com/support/supportedplatforms/workbench.html.

So, even if you’re not using any of the recent versions and editions of Workbench (Utilities comes with all of them, Tools menu -> “Start Shell for MySQL Utilities“) you can just download the standalone scripts on a Linux machine. Flexibility being the name of the game again. …

Ok, so after all the things that have been announced @MySQLConnect, I’ve got to play around with them. First stop: space (no.. not ‘the final frontier’).

I need more space on my f/s to get installing. I was a bit of a scrooge when I created my Oracle Linux virtual machine, so now I’m paying the price.

Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_ol63uek01-LogVol01
                      7.1G  5.7G  1.1G  85% /

As I’m using Virtual Box, I’ve added a new SATA Controller vmdk of 10G, SATA Port 1 and then start it up.

fdisk -l

Will be able to identify the new & unused partition:

Here’s a look at using MySQL Enterprise Backup in a specific example:

Consider a Backup Policy – Full Backup of the environment. – Complemental Incremental backups & online BinLogs. And the Restore: – Logical Restore. – Online, Zero impact. – Partial, single database, group of tables. The Backup A working environment, with 4 databases, of which 2 will require restoration. Full backup with MySQL Enterprise Backup:

mysqlbackup --user=root --socket=/tmp/mysql.sock \
  --backup-dir=/home/mysql/voju5/backup/ \
  --with-timestamp backup

Test preparation Create 4 different databases, where the structure & content is the same.

create database v5_1; use v5_1; create table `voju5` (
  `ID` int(7) NOT NULL AUTO_INCREMENT,
  `Name` char(20) NOT NULL DEFAULT '‘,
   PRIMARY KEY (`ID`) ) ENGINE=InnoDB;
create database v5_2; use v5_2; create table `voju5` (..);
create database v5_3; use v5_3; create …

Well.. just wanted to share the more technical details I went into when preparing the “A MySQL Odyssey: A Blackhole crossover” for the OpenSUSE Conference in Thessaloniki, July 2013. There’s a youtube version as well, of the actual session, on the opensuse channel. http://youtu.be/Nt2w1UvKEp0. (Audio kicks in at minute 6:40 so enjoy my miming act).

Oracle Linux had a lot of engineering hours inside it to drive the performance to new levels. But currently oracle Linux 6.4 comes with a dated version of MySQL, version 5.1.69. So how can you upgrade to 5.6 without losing your data?

First, make a backup just in case Murphy’s Law has a tort waiting for you.

Remove the old files. The rpm -qa | grep -i ^mysql command will show you the packages to be removed. Then rpm -e mysql-server-5.1.69-1.el6_4.x85_64 mysql-libs-5.1.69-1.el6_4.x86_64 and mysql-5.1.69-1.el6_4.x85_64 to remove them.

Thirdly, download the big MySQL 5.6 bundle for Oracle Linux. Untar the bundle and then a quick rpm -Uhv MySQL-*.rpm will install the files.

There is ONE big difference. MySQL as of 5.6, forces a default for the MySQL server and places it in /root/.mysql_secret and you will see to set a new password upon …

1. Create a separate data and log directories


# mkdir /var/lib/mysql2

# chown -R mysql.mysql /var/lib/mysql2

# mkdir /var/log/mysql2

# chown -R mysql.mysql /var/log/mysql2

2. Create a new mysql configuration file


# cp -R /etc/my.cnf /etc/my2.cnf

For Ubuntu Linux


# cp -R /etc/mysql /etc/mysql2


3. Edit the new configuration file


# nano /etc/my2.cnf

# change/add the following options

port = 3307

datadir = /var/lib/mysql2

socket = /var/lib/mysql2/mysql.sock

# add [mysql_safe]

log-error = /var/log/mysql2/mysql.log

pid-file = /var/lib/mysql2/hostname.pid

OR (For Ubuntu Linux)
