A/UX, NeXTSTEP, & OS X

One thing that gets tedious in the IT community and Oracle community is the penchant for Windows only solutions. While Microsoft does an excellent job in certain domains, I remain a loyal Apple customer. By the way, you can install Oracle Client software on Mac OS X and run SQL Developer against any Oracle Database server. You can even run MySQL Workbench and MySQL server natively on the Mac OS X platform, which creates a robust development platform and gives you more testing options with the MySQL monitor (the client software).

Notwithstanding, some Windows users appear to malign Apple and the Mac OS X on compatibility, but they don’t understand that it’s a derivative of the

MySQL Enterprise Backup 3.10: Teasing compression.
Employee +0 Vote Up -0Vote Down

Ok, so I wanted to look into the new compression options of MEB 3.10.

And I would like to share my tests with you. Remember, they’re just this, tests, so please feel free to copy n paste and obtain your own results and conclusions, and should I say it, baselines, in order to compare future behaviour, on your own system.

An Oracle Linux 6.3 virtual machine with 3Gb RAM, 2 virtual threads, on a 1x quad core, windows laptop. Not pretty, but hey.

So, these tests are solely about backup. I’ll do restore when I get some *more* time.

 

First up, lets compare like with like, i.e. MEB version 3.9 & 3.10:

Let’s make this interesting, hence, want to use as much resources available as possible, read, write, process threads and number of buffers.

Mac Mini to the rescue
+0 Vote Up -0Vote Down

In teaching, I had a problem because my students have different base operating systems, like Windows 7, Windows 8, Linux, and Mac OS X. I needed a teaching and lecture platform that would let me teach it all (not to mention support their environments). That meant it had to virtualize any of the following with a portable device:

  • Windows 7 or 8 hosting natively an Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
  • Windows 7 or 8 hosting a Fedora or Oracle Unbreakable Linux VM (3 or 4 GB) with Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
  • Mac OS X hosting a Fedora or Oracle Unbreakable Linux VM (3 or 4 GB) with Oracle Database 11g XE,

Oracle Linux 6.5, MySQL 5.5, 5.6 & 5.7
Employee +1 Vote Up -0Vote Down

So how do you get MySQL 5.5, 5.6, or 5.7 on the latest Oracle Linux? Morgan had a great post on Installing MySQL 5.7 DMR3 with the official yum repos. This blog is about uprading from Oracle Linux 6.4 to 6.5 and getting a recent version of MySQL installed.

The first step, if you are running Oracle Linux 6.4, is to type yum install to upgrade to 6.5. Be sure to read the release notes and that you are pointing to the Public Yum Repository.

Use can use the Add/Remove Software tool to install MySQL 5.1. But who wants to run an old version of MySQL on a new, hot Linux. But let’s pretend you did install 5.1 when

MySQL Utilities: copy, replicate, show, failover… over and over again.
Employee +3 Vote Up -0Vote Down

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 (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

OL 4 MySQL: Extending my VM’s root f/s online
Employee +0 Vote Up -0Vote Down

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.

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

MySQL Enterprise Backup: PITR Partial Online Recovery
Employee +3 Vote Up -0Vote Down

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 '‘,

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 6.4 and MySQL 5.6
Employee +1 Vote Up -2Vote Down

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
