Installing Oracle VM Manager 3.2.x under Dom0 host
+0 Vote Up -1Vote Down

Some of you know that I have published how to install Oracle VM Manager (OVMM) on a Dom0 host since Oracle released the Oracle VM 3. I have described why you possibly may want to do it in my very first post. Just want to mention here that it should be used for sandbox configurations only. You can find the previous post on how to install 3.1.1 OVMM version under Dom0 here. This time I talk about 3.2.2 version.

NOTE: At the time of writing ORACLE VM 3.2.3 SERVER (Patch 16410428) and ORACLE VM 3.2.3 MANAGER (Patch 16410417) became available. I didn’t have time to install the latest versions yet. However I do not

About MySQL 5.6
+14 Vote Up -2Vote Down

I am very excited and thrilled to use the latest release of MySQL 5.6 in production. This is probably the most notable and innovative release in many years, if not ever.

During the last year, we had the chance to work with many new features and test the fixes to old issues. To be honest, I was expecting to have MySQL 5.6 GA before now, and I even wagered with my colleague Francisco that it would be out before the end of 2012. It was nothing special, just a beer in the Santa Clara Hyatt lounge. Unfortunately for me, MySQL 5.6 is now in GA and given that it happened in 2013, I lost the bet and now have to pay for that beer. But I have also lost the full list of things that we saw as relevant, interesting, or really innovative for MySQL.

So I took a step back, took some time, and reviewed what Oracle delivered in this new MySQL release.

Short premise

Quiet Release MySQL Plugin 12.1.0.1.2 — Bug Fixes
+1 Vote Up -0Vote Down

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.


If you didn’t know that you could setup threshold and customized the thresholds that are set out of the box with the plugin, then you are not fully using Enterprise Manager. You can do that in the MySQL target menu — Monitoring -> Metric and

MySQL Oracle Connect 2012: Day Two
+1 Vote Up -0Vote Down

Another good day today: I attended the keynotes and found them quite interesting.

I especially liked the way Twitter uses MySQL to build up a NoSQL solution. Jokes aside, I took a few notes on things I must analyze and dig in.

The introduction of the Paypal models seemed very interesting, which brought me to attend the presentation later on. It was well constructed and had some good theoretical work, but I was quite disappointed. I found the presentation incomplete and missing real numbers for the MySQL Cluster NDB setup.

I attended the presentation done by Ronald B. It was good — nothing really advanced, but it was on purpose. He was very informative and explanatory for a junior MySQL DBA, and I enjoyed his presentation for the logical approach and construction.

Ronald also highlighted that it was the content of less then a chapter of one of his books and was done on purpose to

MySQL Oracle Connect 2012: Day One
+2 Vote Up -0Vote Down

I attend five sessions today, and I think that some of them were very interesting, like the one on the Optimizer insight. It was quite informative and accurate.

Another one, done by the MySQL Cluster (NDB) group on the installer and new Javascript API interface, left me a little bit…foggy. Why? Because in my mind, one of the most important things to accomplish in NDB is the correct dimensioning of the memory, buffers, possible operation, attributes, and so on. All these things should come from the schema definition review and from the application analysis.

Now given the review analysis of the schema is still not present in the installer, I think that we missed a very important piece of information. When I raised the issue, Bernd mentioned that they were thinking of integrating that as well. It’s a good move, and I hope to see it soon. About the

MySQL Oracle Connect 2012 Keynotes
+1 Vote Up -0Vote Down

I’m excited to be here not only to catch up with old friends and ex-colleagues, but also to witness what seems to be the start of a very significant conference from MySQL.

I really enjoyed the introductions done by Edward Screven and Thomas Ulin. Edward highlighted the fact that MySQL is increasing its presence in the market and in the community. This could be thanks to the unbelievable effort done by Oracle in keeping its production cycle on target. Thomas stressed that point and gave a great description of it. He demonstrated Oracle’s main focus points, which are mainly on InnoDB, with implementation and enhancement of the internal contentions, then on Optimizer improvements and NoSQL integration.

Replication remains a pending issue from my side because if we have the global transaction ID, we still suffer from delay in replication given that parallel

Announcing MySQL Plugin 12.1.0.1.0 for Oracle Enterprise Manager 12c Cloud Control
+1 Vote Up -0Vote Down

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.

I’ve had lots of new features to add, but I didn’t really have much time to invest into completing them all. Finally, I decided to just finish the home page dashboard and clean it up from all unfinished new features. I did, however, finish MySQL Slave configuration and status monitoring, which was the largest gap in the the functionality of the previous plugin. There is no custom UI for MySQL slave
