In November 2013, I took a trip to Europe to present at two great Eurpoean Oracle user group conferences : DOAG (Germany Oracle User group conference) and BGOUG (Bulgaria Oracle User Group) Autumn conference. Although it was my first time to attend them, I had a great time at these two conferences. At the conferences, I got chances to my knowledge in these two great Oracle commuities and also learned a lot and had a great time networking with colleagues and friends.
DOAG 2013 was held in the Germany historical city Numberg. It was one of the largest Oracle conferences in Europe, attended by more than 200o Oracle professions from Germany as well as other Eurpoean countries. Most speakers were also from Europe or USA. Many of speakers were Oracle ACE Directors or Oracle ACE and well known experts on their areas. Oracle Corporation also sent a good number of product managers and technical experts to present the latest changes of the technology. One of the sessions that I attended was the Oracle In-Memory columnar Option session presented by the Oracle In-Memory columnar Option product manager. This presentation gave more detailed information about this latest Oracle 12c new feature than the similar one that was gaiven at Oracle OpenWorld 2013. The session contained the presentation as well as a detailed live demo.
At the DOAG conference, I gave two presentations. The presentation PDF files can be downloaded through the following hyperlinks:
1. Ensure HA in Database Cloud with Oracle Database 12c:What to do and how to do it: 11/19/2013: 11:00-11:45 am , The Nuremberg
After DOAG conference, I traveled to Plovidiv, a famous historical city in Bulgaria to attend BGOUG (Bulgaria Oracle User Group) conference. There are two Oracle conferences held in Bulgaria annually: the Spring conference in May , and the Autumn conference in November. The autumn onference attracted several hundred Oracle professions from all over Bulgaria. The majority of speakers were from Bulgaria as well as other other Eurpoean countries plus few from US and non-Eurpoean countries. The two presentations I gave had the same titles as the one that I presented at DOAG with some minor changes on the contents:
The six sessions that I will co-present at OOW13 are related to the following technologies: Oracle 12c Pluggable database, Oracle 12c Flex Clusters, Oracle 12c Flex ASM, Oracle VM 3.x, Oracle EM12c, Oracle E-business applications, Dell Blade servers, Dell Compellent Fibre Channel All Flash Array, Dell PCIe SSDs.

Between April 17th and April 19th I was invited to participate the Oracle User Group Norway 2013 conference by giving three presentations. This conference was held in Oslo Radisson Blu Scandinavia Hotel on the first day (April 17th), and then was moved to the Color Major Cruise ship Between Oslo, Norway and Kiel , Germany on the second day (April 18th) and the third day (April 19th).
The conference was one of the best organized conferences I have ever seen. The conference organizers really have done the great job to make this conference such an great experience. There were about three hundred peoples attending the conference, most from Norway plus more than 30 speakers from all over the world. Among them there are many industry well-known speakers such as Tom Kyte , Cary Millsap , Kuassi Mensah, Bryn Llewellyn, etc .The topics covered many areas in Oracle Technology, ranging from Oracle Database and MySQL core technology for DBAs, database and applications tuning, BI/DWH, Development, Middleware and Security. From these sessions, the audiences and speakers can really share and exchange the experiences. It also covered some topics on the Oracle 12c database such as portable database, new high availability features, new security feature. My three presentation topics were:
During these sessions, I had some great discussions with people on the sessions. One thing I really appreciated is that many people attended my PCIe SSD session by giving up the opportunity of sightseeing in the beautiful Germany port city Kiel as this SSD session happened to be in middle of short time when the cruise ship stayed in Kiel and allowed people to have a short sightseeing in the city.
This trip was also my first time of visiting Norway. I really enjoyed visiting many beautiful sighseeing places in Oslo: the Royal Palace Oslo, Akershus Fortress, Oslo City Hall, Opera House, Norway National Theater, Aker Brygge/Oslo Fjord waterfront area . The nice thing about visiting Oslo is that all of these major tourism attractions were within the walking distance of the Radisson Blu Scandinavia Hotel. For this I really want to thank the conference organizer for arranging such a great hotel at the very convenient location.
From the Cruise Line, I was able to see many breath-taken views of the sea port of Oslo and many small islands floating around outside of the port. What incredible views!
It has been a great learning opportunity for me through many discussions on my sessions and as well as by attending other speaker’s sessions. The conference has been a great experience to meet the friends and share experiences with the colleagues in this part of the world. By having a chance to get to know the people and colleagues that are working on the same area, we can expect more collaborations and knowledge sharing to continue after the conference.
I will really look forward to coming back again next year or in future to participate the conference.
Oracle just announced the Oracle OpenWorld 2013 call for papers today!
The call for papers will last about one month and close at Friday, April 12, 11:59 p.m. PDT. For those of us who want to share their experences and technology inovation at this biggest information technology event in the world, we need to come up some topics and submit to the conference commitee by the April 12th deadline. Since 2006 Oracle OpenWorld when I gave my very first presentation at this event, I have been very fortune to speak at the conference 16 times. I look forward to having another year to continue my contributions to the conference.
I listed all of my previous Oracle OpenWorld presentation for reference. Here I want to thank the people who also contributed to these presentations including my co-speakers of some sessions, and the conference commitee who gave me the opportunity to present and the audiences who participated and supported me during the presentations.

It was a great honor for me to recieve the industry prestigeous award “2012 Oracle Excellence Award: Technologist of the Year for Cloud Architect ” from Oracle Mazgine. Although I received this award at Oracle OpenWorld 2012 in San Francisco in early Octorber 2012, the award was officially announced on the Oracle Magzine’s January/Feburary 2013 issue .
My original backgroud was Oracle DBA and Oracle Applications DBA. My experiences was mainly on managing large Oracle RAC databases and Oracle E-Business applications suite running on complex muitple nodes environment such an Oracle Grid. In late 2008, as a part of addtional responsibilites of my job, I started working on Oracle virtualization technology specifically Oracle VM for X86-64 platform . Since then Oracle VM has become of one of my favour technologies. Natually I started looking at the best practices of running and deployment Oracle RAC databas, Oracle E-Business suite applications on the Oracle VM enviroment. The Oracle OpenWorld 2009 confernece allowed me to give three presentation sessions about my work on Oracle VM technology:
And the contents of these presentations were also published in three whitepapers:
In 2010, Oracle Introduced the Oracle E-Business Oracle VM template. I was working on a project for which I needed to deploy Oracle E-Business Applications on Oracle VM environment . However I noticed that the Oracle EBS VM template downloaded from Oracle was a general template for the Oracle EBS vision instance. For the project, I needed to find out a way to virtualize the exisiting production Oracle E-Business suite system that currently ran on the physical environment . That is the backround that I came up the solution to migrate the Oracle EBS suite t to a virtual environment. As a result of the project, I put toegther a whitepaper about this solution:
and also presented this solution at several Oracle conferences:
I also worked on provisioning database and applications using Oracle Enterprise Manager’s Software library and provisioning procedures It can be considerred the early version of Oracle Cloud application provioning methods. Built in with Oracle Enterprise Grid control 10g, this method can quickly provision multiple node Oracle 10g RAC . Some of the early projects were presented at Oracle OpenWorld and Collaborate conferences:
- Automatic Oracle RAC Deployment and Implementing MegaGrid using Oracle EM Provisioning Pack, Oracle OpenWorld 2007, October 2007 San Francisco, California.
- Case Study: Implementing the Oracle Grid Computing on Dell Hardware for Multiple ERP Applications, Oracle OpenWorld 2008, November 2008, San Francisco, California.
- Provisioning Oracle RAC in a Virtualized Environment, Using Oracle Enterprise Manager, Oracle OpenWorld 2009 presentation, October 2009, San Francisco, California.
- Oracle RAC on Oracle VM Automated Provisioning with Enterprise Manager 11g , Oracle OpenWorld 2010, Sept. 19, 2010, Session ID: S316318.
As a part of Oracle Enetrprise Manager 12c cloud beta efforts, I worked with Oracle EM12c product engineers and product managers on a Dell | Oracle joint Oracle cloud project. This project aimed to architect and implement a privare cloud solution based on Oracle VM and managed by Oracle Enterprise Manager 12c. By importing Oracle VM templates into the Oracle Enterprise Manager 12c’s software library, on this project we were able to implement the self service provisioning of applications in the Oracle cloud environment using Oracle VM templates. The result of this project was presented at Oracle OpenWorld 2011, right after Oracle officially announced Oracle Enetrprise Manager 12c, total cloud control solution.
In 2012, as Oracle released new version of Oracle VM 3.0, we upgraded this cloud to Oracle VM 3.1.1 and implemented the self provisioning multiple tier applications using Oracle virtual assembilies. the newer version of Oracle cloud was presentated at Oracle Openworld 2012:
Another area I have worked on is the Oracle database cloud based on Oracle RAC technology with or without Oracle VM:
These are some of presentations that I have given on this area:
- Implementing Oracle Applications 11i on 10g RAC and ASM, Oracle OpenWorld 2006, October 2006 San Francisco, California.
- Implementing Oracle E-Business Suite R12 Through 11i to R12 Upgrade Path, OAUG Collaborate 08 presentation(April, 2008, Denver ,Colorado), Oracle OpenWorld 2007 Presentation (October 2007 San Francisco, California) (this present discussed the step by step method to migrate an Oracle EBS 11i with single node database to Oracle EBS R12 with a multiple node RAC database.
