1- Why did you choose to specialize in Oracle databases?

Before I was a DBA, in my first IT job after college, I worked with databases as a developer and the application
environment was mostly Oracle. This provided me with incentive to learn Oracle.

2- What made you specialize in Oracle Real Application Clusters and Linux systems?

Years ago, when I first began working as an Oracle DBA, I had to work on an Oracle 7 OPS (Oracle Parallel Server) on SunOS UNIX platform. This was the precursor to Oracle RAC and I enjoyed the challenges. I continued working with RAC as the product matured and it became a focus in my database forte. Since I had a solid network and storage background before I was an Oracle DBA, it made sense since a good Oracle RAC DBA must know these things in addition to Oracle. As for Linux, I worked mostly over past decade on UNIX systems with Oracle and with the evolution of Linux, it made sense as Oracle has shifted from developing on Sun Solaris to Linux platform.

3- Do you still remember the first day in your first job?

Yes, in college, to pay for school, I worked for the computer lab on campus. I had to enter thousands of pages of data entry in a mainframe computer! It was horrible but my first paying tech job before graduation so I accepted the drudgery and never complained. My boss was appreciative and let me train on databases as result! I learned SAS, UNIX, and Oracle.

Kellyn lives with her three children in Broomfield, CO and currently is honing her technical skills at I-behavior, a marketing firm in Louisville, CO.

 


 

1- Why did you choose to specialize in Oracle databases?

I’ve often had the official title of “Multi-Platform DBA”, having just as many years in SQL Server as I do in Oracle and numerous years in other platforms, such as Informix and MySQL. In all honesty, I just don’t have the technical challenges or large databases to work with in other platforms that I have in Oracle. Business’ know that Oracle has the “horse power” to do what other database platforms can not. It has, (in my honest opinion…) the features built in to support robust databases, along with forward thinking solutions like Exadata that other companies are either technically behind or stagnate in. I may come across aspects in MySQL, Informix and SQL Server that I appreciate, but none of them compare to Oracle’s CBO, Recovery Manager, Dataguard, Exadata and others.

2- Is there anybody you have regarded as role model at the beginning of your career?

I can clearly admit that I have my “Oracle Gods”, a role granted to 9 experts, even after 11 years as a DBA. I had the opportunity, as a Junior DBA to work with my first “Oracle God”, Tim Gorman, while he worked on a few contract with the company I was employed with and he quickly became the standard as to what I expected DBA God to be. He was technically brilliant, cool under pressure and easy to learn from. Our roles have changed in the 9 years I have known him, but he will always be my first DBA God and a standard I also hold myself to. There are a ton of brilliant DBA’s out there, but if they spend too much of their time attempting to prove they “are the smartest person in the room” or simply stagnating another’s growth as a DBA, I find less value in them than other’s might. Arrogance and closing another’s mind to knowledge is not an asset- it’s a liability in the database arena. Our best teachers are other DBA’s, so those who monopolize this to make themselves feel superior do not achieve DBA Godhood in my book. I have slowly added others to the DBA God list, (James Koopman, Tanel Poder, Wolfgang Breitling, Alex Gorbachev, Cary Millsap, Kerry Osbourne, Martin Widlake, Kevin Closson and various demi-God’s that I won’t list here…:)) They have all shown to be great teachers, willing to share their knowledge and commonly known for their desire for other’s to succeed as they have.

Entrevista con Nelson Calero – Presidente del UYOUG y Experto en Oracle RACEntrevista con Nelson Calero – Presidente del UYOUG y Experto en Oracle RAC

August 24th, 2011 | Posted in Interviews | 3 Comments



Nelson Calero trabaja desde 1994 con tecnología Oracle, inicialmente en desarrollo de aplicaciones para luego especializarse en administración de bases de datos Oracle y MySQL, arquitectura, performance y alta disponibilidad. Ha estado a cargo de proyectos en varios países de América Latina. Actualmente brinda consultoría en diversas empresas y es instructor de Oracle University. Co-fundador y Presidente del Grupo de usuarios Oracle de Uruguay (UYOUG), y Latin America Chair del Oracle Real Application Cluster Special Interest Group (Oracle RACSIG).

 


 

1- ¿Por qué eligió especializarse en bases de datos Oracle?

Cuando estaba finalizando la carrera de Ingeniería comencé a trabajar en una empresa que estaba migrando sus sistemas de mainframe a Oracle. Era la versión 8i en el año 1996.
Allí tomé varios cursos oficiales Oracle, y programaba usando PL/SQL, Designer, Forms y Reports. Desde entonces estuve siempre vinculado a proyectos con tecnología Oracle. Los siguientes seis años fueron en distintos roles de desarrollo, y también en menor dedicación con tecnología variada (PalmOS y C). Fue así hasta que entendí que no podía abarcar tanta variedad y necesitaba especializarme, para evitar el stress de cambiar cuatro veces por día de clientes y problemas, y para poder ser realmente experto dominando un área en profundidad.
Los desafíos existentes en el área de bases de datos le ganaron al resto, así que desde hace nueve años me dedico exclusivamente a ellos.

2- ¿Todavía recuerda su primer día de su primer trabajo?

Siendo estudiante en la Universidad, fui becario en una empresa estatal que tenía uno de los centros de cómputo más grandes del país. Ese día fueron muchas caras nuevas y muchos manuales de estándares y metodologías para leer. Nada muy técnico. Desde entonces han habido muchos primeros días, y sigo disfrutando esa sensación que acompaña los nuevos desafíos, además de la oportunidad de compartir y aprender.

1- Why did you choose to specialize in Oracle databases? 

My interest with database started with my Mater degree thesis research on relational database more than 20 years ago. My Oracle database career started in 1995 shortly after when I took a database engineer position in a software company working on OCI and C++, PL/SQL and DBA. On that job, I really enjoyed learning and working on Oracle database technology on both applications development side aas well as the database administration side. The technology really fascinated me and I decided to pursue my career in Oracle database.

2- What made you specialize in Oracle Real Application Clusters and Linux systems?

My first involvement with the Oracle cluster database was the Oracle Parallel Server (OPS) in 1997 when I worked for the factory automation system in Samsung Austin Semiconductor . In 2001-2002, I started working on Oracle databases running on Linux and around 2003-2004 I started deploying and managing Oracle RAC databases on Linux in Dell IT. We managed more 2000 production Oracle RAC databases on Linux systems, and 2-3 times of development and test RAC databases in our DBA team, including those for Oracle E-Business Suite applications and large data warehouses. In late 2006 I joined in Dell Oracle Solutions Engineering team and worked on engineering solutions for Oracle RAC on Linux and Dell systems. I have been working and living with Oracle Real Application Clusters and Linux systems in last 8 years. Most of my conferences papers and whitepapers were Oracle RAC related ranging RAC best practices, Oracle EBS on RAC, Oracle EM for RAC, to Oracle RAC on Oracle VM.

Interview with Fahd Mirza – Oracle ACE and Oracle Expert

August 15th, 2011 | Posted in Interviews | 2 Comments

  Fahd Mirza is an Oracle Certified Professional (OCP) in 11g DBA and 10g DBA He has been working with Oracle products since 2001 including Database Administrator, Application Server Administrator and Oracle RAC Administrator, with proven skills in managing Oracle databases (OLTP and Data warehouse) and Application Servers on Solaris, Linux, HP-UX and Windows Servers. Fahd is an avid blogger and active member on OTN. He is currently working at Pythian.

 

 

 


1- Why did you choose to specialize in Oracle databases?

I have a passion for data and that is why I pursued this career in IT and especially data management. While evaluating different technologies for the DBMS during my master’s thesis, Oracle stood out exceptionally. From my master’s theses to this day after eleven years, I am managing the Oracle databases and related technologies. Also, the fact that Oracle innovates almost on weekly basis and it never fails to challenge the DBAs is the engine behind my love for Oracle and its technologies. These days I am managing the Oracle Exadata database machines at Pythian for clients.

2- Do you still remember the first day in your first job?

Yep, was so excited, fearful and hopeful. I was thrown right at the database server, and the expectation of the employer was that I would be managing the operating system, database, storage, capacity planning, and hardware procurement and dealing with support. I am glad that he expected that, because that pressure solidified me in my early years.

1- Why did you choose to specialize in Oracle databases?

Oracle Database makes me feel challenge. When I work on Oracle Database product, I can integrate something what I know about Operating System, Storage, Network, Security and Application. However, I like Oracle Community. First time, I found Oracle Database issue, I asked on OTN Forums and then someone helped me to figure it out.

2- What made you specialize in Oracle Real Application Clusters and Linux systems?

I am not specialized in Oracle Real Application Clusters and Linux systems. I just know about them. If you would like to specialize in Oracle Real Application Clusters and Linux systems. You should learn from Blogs of Experts, spend time to test them and join their available communities. Finally, don’t miss to share.
Oracle Real Application Clusters, I advice to join Oracle Forums and then learn from it. If you have account on My Oracle Support, you can find out more useful information.

When you would like to specialize in something, you should like it. You like it, don’t you?

Interview with Debra Lilley – Oracle ACE Director and UKOUG President

August 7th, 2011 | Posted in Interviews | 3 Comments


Debra Lilley is Oracle Alliance Director for Fujitsu, she has worked with Oracle applications since 1996 (EBS 9.4.1) as Support Manager, Functional Consultant, Discoverer and then BI lead. Her role is now about strategy and education of both Fujitsu people and customers. She is President of UKOUG and Chairman of the Product Development Committee at the IOUC. She was User Group Evangelist of the Year in 2008.

 


 

 

 

 

1- What made you specialize in Oracle EBS, fusion technology and applications?

I had been a developer, in both Cobol and Ingres, but moved more to analysis and consulting. When my employer Fujitsu started an Oracle Applications (EBS) practice in 1996, I joined the team to run support as I had both technical and functional skills. I really enjoyed working with the applications, and although have changed my role many times, am still in the practice. I am very interested in the technology and how it gives business benefit, but I am not a technical practitioner
When Oracle announced Fusion Applications, they told the IOUC (Global User Group Community) that they wanted to work with users groups but needed a single channel. I volunteered to lead that channel to ensure UKOUG had a big say. I didn’t expect it to take so long and during the journey I realised it was ALL about the technology and the User Experience it delivers.

2- Do you still remember the first day in your first job?

My first day in computing was a nightmare, I was learning Cobol and forgot the end statement in a print loop, they stopped it when the paper ran out!

1- Why did you choose to specialize in Oracle databases?

It just happened to be in the right place and at the right time . It was in 1994. I was a COBOL programmer working for a big steel company in Saudi Arabia. Management decided to replace COBOL with Oracle. So, I had to learn SQL, PL/SQL, Oracle Forms and Reports. We were running Oracle Database version 7 on VAX/VMS. That’s when I entered the vast world of Oracle… the rest is history.

2- Do you still remember the first day in your first job?

After I graduated from college with a shiny new Computer Science degree, I went into teaching for a while. I taught math, English and (COBOL and FORTRAN) programming. Even though I enjoyed teaching, it was not an easy job to do.

I wanted to live in San Francisco and Oracle was the only company in 1989 recruiting on campus at Cornell from San Francisco.  Living in San Francisco was my goal and Oracle got me there. At the time  I thought databases were boring having majored in physics and mathematics. I had wanted to work on numerical models of  trading systems and arbitrage calculations.

2- What made you specialize in Oracle Performance Tuning?

I like finding patterns in quantitative data whether it’s the stock market or databases. Oracle performance tuning has given me this opportunity.

Interview with Hans Forbrich – Oracle ACE Director and Oracle ExpertInterview avec Hans Forbrich – Oracle ACE Directeur et Expert OracleEntrevista con Hans Forbrich – Oracle ACE Director y Experto OracleEntrevista con Hans Forbrich – Oracle ACE Director y Experto Oracle

Please choose your language by clicking on the flag.


In 1969 I had the opportunity trough the University of Calgary (UofC) to use their computers and write my first program. Not long thereafter, in the 1970s I worked as a contractor writing Fortran programs to pay for my university education. Perhaps the most interesting thing in my history is that I attended UofC Electrical Engineering at the same time that James Gosling attended the same school in Computer Science.

 


 

 

 

 

 

1- Why did you choose to specialize in Oracle databases?

It was almost an accident. I worked for a large company in the 1980s, designing systems and writing programs on those systems and on IBM mainframes using PL/I and a database language called GERM (General Entity Relationship Model). In the end, my group was responsible for the Support systems, and I became team lead to rewrite the systems into a commercial RDBMS in 1984. During the evaluation between Oracle (v4), SQL/DS, DB2, Ingress and others, I was impressed by Oracle’s high availability and selected that as the preferred product. Another key to the selection was a meeting with the Oracle people and discussions about networking ideas and distributed computing.

2- Do you still remember the first day in your first job?

I remember many ‘first days’ on the job. Each job was filled with opportunity and challenge, and I eagerly stepped up to each. Interestingly, Oracle followed me, rather than me follow Oracle. At Nortel, I was an engineer responsible for designing, and later servicing telephone systems. That led me to databases, Unix and C programming and eventually to architecture. At DLGL, an HR applications company, my experience helped create their system standards and architecture, much of which is still found today. When I joined Oracle in 1996, just as Oracle was expanding into 3-tier computing, my whole universe expanded to include the web and network computing, and the new beast called Java. That was exciting.

But the best ‘first day’ was in January of 2003, when I started my own company which had, and still has, the purpose of “optimizing Oracle investment” though training, performance, license awareness and most of all, though understanding what functionality the customer has purchased.
