MySQL : What management tools do you use?

A quick question out to the world. What management tools do you use for MySQL?

We currently have:

MySQL Upgrades

I read Wim Coekaerts post about the MySQL 5.6.20-4 this morning. I logged on to my server and did the following command as root.

# yum update -y

That’ll be the upgrade done then… :)

If you are using MySQL on Linux you can use the MySQL Repository for your distribution, rather than using the bundled MySQL version, to make sure you stay up to date with the latest and greatest. As long as you stay within a point release (5.6, 5.7 etc.) of the latest version, upgrades should really be as simple as a “yum update”.

Oracle Linux and MySQL : Progress

A few months ago I wrote about some MySQL on Oracle Linux migrations we were working through. It’s been a long time coming, but last weekend was the go-live for this batch of migrations. So far so good! :)

Most of the elapsed time since my last post on this subject has been spent with the developers and users testing the migrations.

Oracle Linux and MySQL

I’m in the process of taking on some of the MySQL databases in my company. The first ones are MySQL 4.1 running on Windows, so we are upgrading them to MySQL 5.6 on Oracle Linux. As with many of our systems, these will be running on VMware virtual machines.

Since the current installations are so old, we are planning on dumping out the data and creating fresh installations on the new systems. Based on the advice I got from Ronald Bradford and Sheeri Cabral, we are also taking this opportunity to switch to InnoDB and utf8, rather than MyISAM and latin1 that are currently used.

Quiet Release MySQL Plugin 12.1.0.1.2 — Bug Fixes

This is just a small bug-fix release of the plugin. It has actually been quietly released for a while now. If you have downloaded the plugin recently, you have the latest version. To be sure, check the version in the Console, or you can see it in the file name.

There are two bugs fixed:
1. Deployment on an OMS hosted on Solaris didn’t work. (And I suspect it could be the same for Agents on Solaris.)
2. Changing thresholds on the metrics caused the error “Modification of Target Monitoring Settings has Failed”. Also, applying monitoring template was failing for the same reason.

Announcing MySQL Plugin 12.1.0.1.0 for Oracle Enterprise Manager 12c Cloud Control

MySQL management plugin for EM 12c has been long overdue. I’ve initially migrated the older plugin to EM 12c about 6 months ago, and few dozen people received this as the initial beta of the plugin. It worked OK but didn’t use any of the new 12c features, and its home page was a bit of a mess in the EM 12c Cloud Control web interface.

Hardware Components Failures – Survey Results

When preparing for the the IOUG Collaborate 12 deep dive on deploying Oracle Databases for high Availability, I wanted to provide some feedback on what hardware components are failing most frequently and which ones are less frequently. I believe I have reasonably good idea about that but I thought that providing some more objective data would be better. I couldn’t find and results of a more scientific research so I decided to organize a poll. This blog post shows the results and I promised to share it with several groups.

Announcement: Release 1.1.2 of MySQL Plug-in for Oracle Enterprise Manager 10g/11g

This release is just a quick bug fix release of an older 1.1.1 version of the plug-in. It’s long overdue but I’ve managed to fix “” problem only couple weeks ago. I’ve distributed the new version to the folks who have reached out to me by email of via blog reporting the issue in the [...]

Thirteen signs of DBA fudging

If you are a director, manager or project manager who works with DBAs, you probably have had the nagging suspicion at one time or another that a DBA’s assertions regarding his or her practices lack an empirical or scientific basis, or are simply deflections intended to pass the buck.

Manager: Mr. DBA, the application is really slow. Do you have any idea what’s wrong?

DBA: Oracle is very complex. It could be any of 100 different possible causes. I will begin checking each. Anyhow, what makes you think it is the database?
