OL 6.5 was released a few days ago to ULN and public yum, and of course I was going to upgrade some machines immediately. But first: Have I mentioned before that I really love Oracle Linux for providing ISOs and patches for free? One of our customers insists on using Red Hat instead of OL. No problem so far but a few days ago we needed to clone that VM for some testing and staging. Only problem: to do this we needed another support subscription from RH which the customer is paying for but more importantly it delayed the project since we now had to wait for procurement. This is why I appreciate the license model of OL: you can use it for free and have the option of purchasing support for the machines that are most important to you. Also, licensing is per (hardware) server, not VM. Read more about OL licensing directly from the horses belgian’s mouth. Continue reading →
What a shame to be spending a warm, sunny summer day in a hotel’s conference center. Even though it was a really nice hotel and a very interesting conference. About 300 attendees mostly from Western Australia found their way and I was happy to see some fimiliar faces in Tariq, Pete and Connor McDonald who is local to Perth. After having been spoiled with really good espresso in Auckland, the coffee in Australia was a bit of a letdown but that should remain the only thing to complain about. Continue reading →
The day started way too early for me when my body decided that 3am NZ time feels like the middle of the day back home. Fortunately though this country has great coffee and by the time the OTN day started at the campus of the University of Auckland I had already downed 5 espresso beverages. It was great to see Tariq Farooq and Pete Sharman so soon again after OpenWorld and I got to meet Francisco Munoz Alvarez in person for the first time. The audience had a few familiar faces with DBvisit’s Anton Els (who had presented a webcast himself earlier that day) and Mike Donovan who I had met at Collaborate and OpenWorld earlier this year.

I am excited. This is the first OTN tour that I am participating in since becoming an ACE Director earlier this year. There are a few of these tours every year where a group of ACE Directors and other speakers visit a few conferences or special one-day events in a region back to back. The goal is to promote Oracle technology to the local user communities and get technical content to the attendees. The tour starts with a day in Auckland, New Zealand, then the two day INSYNC conference in Perth before heading to the northern hemisphere to Japan and two stops in China. Unfortunately, I am only able to join for the Australian and NZ stops in order to be back in time for the annual DOAG conference later this month. Continue reading →
This is it! The challenge for this year’s blogger meetup was to produce a video of the meetup, and without giving it much thought I just filmed everyone who got in front of my phone and asked them to do silly stuff or answer random questions. While putting together a brief trailer with iMovie was really quick and simple, adding the rest of the material for a “proper” video proved to be much more time consuming. I spent quite a few nights cutting clips, rearranging stuff, synchronizing to music etc. But I loved the process since I love everyone in this film and did not mind seing the same clips over and over again. I hope you will enjoy watching it as much as I did making it and being in San Francisco with this unbelievably energetic and smart crowd.
I love the annual blogger meetup at Oracle OpenWorld and I cannot resist a good challenge. Every year, Alex comes up with a new task on what or how to blog about the event and you can read my past entries here (2010), here (2011) and here (2012). The challenge for this year was to create a video of the event. So I got out my phone and shot a ton a tiny clips at the event without a real idea of how to put it all together. But the first product is here, I created a small trailer with some of the familiar faces. Can you name all the stars in this clip?
Ich gebe Heute für die DOAG einen Webcast zum Thema RAC Connection Management, ein Vortrag, den ich so ähnlich schon mehrfach präsentiert habe. Neu sind einige Ergänzungen zu den Features, die mit 12c hinzugekommen sind. Da die (virtuellen) Plätze für den Vortrag schon länger beinahe komplett vergeben waren, habe ich im Vorfeld gar nicht viel Werbung dafür gemacht, sorry falls der eine oder andere sich das auch gerne angesehen hätte und keinen Platz mehr bekommen hat.
Aber ich habe hier die Folien vom Vortrag zum Nachlesen. Der Webcast wird aber wohl auch aufgezeichnet und steht DOAG Mitgliedern dann hinterher auch noch zur Verfügung.
Und es gibt auch noch einiges mehr zu entdecken. Zunächst einmal laufen im Moment die Wahlen für den Vorstand der RAC SIG, und ich habe mich dort als Vice President beworben. Für den Posten des European Chair stehen mit Bertrand Drouvot, Ludovico Caldara und Okcan Yasin Saygili gleich drei tolle Kandidaten für meine Nachfolge zur Auswahl.
Das RACattack Projekt wurde komplett überarbeitet und enthält jetzt Schritte für die Installation eines 12c Clusters mit pluggable databases und VirtualBox als Virtualisierungslösung, so dass auch Besitzer von Mac oder Linux laptops die labs installieren können. Auf der OpenWorld in San Francisco werden viele RACattack Ninjas am Montag und Dienstag von jeweils 10:00 bis 14:00 mit Rat und Tat beim Installfest in der OTN Lounge zur Verfügung stehen.
Wer noch mehr Details über Hochverfügbarkeit mit RAC in Applikationen lernen möchte, sollte auf der DOAG Konferenz im November auf keinen Fall den Vortrag von Sebastian Solbach verpassen, der hier technisch wesentlich tiefer gehen wird als ich in meinem Webcast.
Und auch wenn es auf der diesjährigen DOAG Veranstaltung leider keinen großen RACattack Workshop geben wird, lässt sich hoffentlich ein unconference spot finden, in dem ich gerne zeige, wie so ein 12c RAC Cluster auf dem Laptop laufen kann. Außerdem möchte ich eine Demo mit einer einfachen Java Applikation zeigen, die dank UCP und application continuity den crash einzelner Datenbankinstanzen unbeschadet und für den Anwender unbemerkt überlebt.
Just four more weeks until the ultimate geekfest kicks off in San Francisco. Over these past years, a few sporty side-activities have emerged and it seems like some of them are becoming quite a tradition. So in case you missed things on twitter or facebook, this is your guide on how to stay (or become) fit during the OpenWorld week.
Sunday, 9/22/2013 08:00AM: Golden Gate Bridge fun run
Join SQL Developer product manager Jeff Smith and others for an easy jog over the Golden Gate Bridge and back. The distance is about 5-6k (3.5mi) and you should expect a very easy pace, this is not a race. Sign up with this facebook group to let people know you want to participate and also to arrange sharing a ride. If you are too cheap for a taxi and/or simply enjoy running, you can join me and run from Union Square to the Bridge and back. It is an additional 8k either way so the total will be about a half marathon. Meet me on Union Square at 7:00AM or be at the south end of the bridge by 8:00.
Monday, 9/23/2013 07:30AM: OpenWorld Swim in the Bay
There is no better way to start a conference day other than a refreshing swim in San Francisco Bay. About 20 daring nerds went into the water last year and had a blast. You will feel refreshed, I promise. The lagoon at aquatic park protects against the currents of the bay and has a nice little beach. There are a couple of buoys marking the distance but the experience is more important than the yards and everyone who goes in the water is a champion. Again, there is a facebook group to sign up. Expect some very exclusive swag, a hot coffee and ultimate bragging rights for the whole week. Meeting point is on the beach at aquatic park, next to the dolphin club at 7:30. In case you are still not convinced: Here is oraclenerd’s report from last year.
Friday, 9/27/2013: Hills and Highway 1 bike ride
We’ll be picking up rental bikes for the weekend after OOW in Los Altos on friday and take them out for a ride. The rough plan is to ride at an easy pace from Los Altos over the hills to the beach and Highway 1 (80-100km, 50-55mi) and end up in the Santa Cruz area. Ole will drive a support van with water and some food and also pick us back up in Santa Cruz and give us a ride back to silicon valley. Let me know if you are interested and we can help with bike rental and logistics.
Sunday, 9/29/2013: Santa Cruz Triathlon
All is well that ends well and this OpenWorld trip will surely end in a big bang as I am planning to go all out at the Santa Cruz Triathlon together with Sten Vesterli and Henning. You can still sign up for this olympic distance event and if the whole shabang is not your cup of tea, they also offer relays.
About two weeks ago, Oracle announced that they had ended new feature development for Oracle Sun Ray and Virtual Desktop Infrastructure along with the Sun Ray thin clients and virtual desktop clients for PCs and mobile devices. They say they’ll keep developing Secure Global Desktop and VirtualBox.
This has started quite a reaction on the Sun Ray Users mailinglist aswell as a number of international (zdnet, the register, Brian Madden) and german media. These products never gained a huge amount of marketshare but there are a number of very enthusiastic and loyal users around it who are now after 15 years left to find an alternative.

During my most recent installation of an Oracle VM 3.2 server pool, I was pondering again all the different options to manage storage with OVM, wrote them down together with pros and cons (to help me decide which one to implement) and now I am sharing these notes.
First of all, you will need to understand the different kinds of storage that OVM can use for all its data. We will start with the easier ones and work our way up. Continue reading →
The short summary here is: there is nothing new to see. There is just a not in the 12c docs that creates a bit of confusion. But let’s go back one step. This blog post started with (what looked like) a simple question by Christian Antognini:
Oracle Restart is deprecated in #DB12c. What would you use instead of it?
Without much thinking, I shot from the hip and answered “clusterware / grid infrastructure” but I had to realize later that I really don’t know much about Oracle Restart. First of all, to me Oracle Restart has been just a stripped down installation of the clusterware. You download and install grid infrastructure to use it and in the end you use srvctl to manage your oracle items (listener, asm, databases and services) like in a RAC or RAC one node environment. Just without a real cluster. It may be more complicated than that but that’s how I see it. And that really may not be the whole truth. Continue reading →
