Hi Fernando,

How much about SPA for mobile devices will be covered in the book, including for wrapped webkit mobile application?

Thanks,
Yukun
Sorry guys, I should've come back earlier to post my news. I did manage to complete part 2 and part 3 within three months time and passed the exam and received the certificate a couple of months later.

It's been three years since that. I haven't experienced a direct benefit from holding a JavaEE architect certificate, since I haven't changed job. But the experience of going through the knowledges, doing the assignment and sitting the exams are quite adorable and glory. Three years later, I still suggest experienced Java developers to challenge yourself for it because the result is you either gain the knowledge by preparing the exam or achieve a great level of confidence in architecting, or both if you pass.

Thank Sharma and Jeanne so much for your posts three years ago. Your posts definitely encouraged me to go ahead and to achieve the great experience and result.
Financial services industry has its special requirements in data usage and data management, such as extreme reliability, real time access, large volume data traffic, strict auditting, historical data analysis, etc.

Are Hadoop and MapReduce designed and proved suitable for those requirements yet?

Your question is fine. The questions are about why you made decisions in your part 2. They don't make questions specific to you, but you need to answer based on your project.



How long will it take for them to process part 2 to appear in their system so I can register part 3, with current high demand in part 2 and part 3 before the deadline? Has anyone had a recent experience?
From memory, I remember that with Prometric it was said to sit part 3 before submitting part 2 assignment, so recently I've tried to register for part 3 through Pearson VUE while approaching to part 2 completion, but failed to register with response from oracle that I must submit part 2 before I'm able to register part 3. Am I understanding the original message from Prometric incorrectly or Oracle/Pearson VUE is violating the original agreement?

Can someone share experience with submission part 2 assignment and registering and sitting part 3 recently through Pearson VUE? Is there new time restriction between submitting part 2 and sitting part 3?

Are part 3 questions specific to the part 2 assignment or just about general non-functional requirements? Hopefully this question is acceptable here.

Thanks,
Thanks for your reply, Robert.

I was thinking that R should have some kind of feature of scalability available for any package so that package developer and R's user can focus on their scientific computing or application integration without need to worry about its performance particularly scalibility. Maybe my thought is too luxury, since it's hard for any computing language.

Hi Robert,

Is R intended to satisfy the requirement of performance for large scale enterprise application, in terms of high speed and high frequency processing, concurrent computing and scalibility, when it is integrated with other languages like Java or C++ or used solely? Does the book R in Action cover similar topics?

Thanks,

Experience wise you are having the right experience and you should try it out.

So it's manageable and i think you should go ahead for that.



Thanks very much for sharing the experience!

Hi,

I have passed part I last year (not a high score). Just yesterday, I heard that Oracle added the requirement of course attendance (I know I'm too late on this), so I'm wondering if it is reasonably possible to get part II and III done including getting the assignment questions, writing the design, submitting the work, preparing for part III and sitting part III essay exam all in three months, plus half a month potentially for resubmission.

Given that I have 9 years commercial experience as developer, technical lead and some architect responsibilities in Telco, Finance and Internet industries, and am currently doing a full time job for one of the top investment banks in a reasonably stressful (or responsible) environment, but I have no experience with airlines system (I guess that's currently the part II is about, correct me if I'm wrong). I can possibly spend around 6 hours after work time per week on the exam, otherwise my wife and son may complain .

I'd like to consult someone who has experience with part II and III whether three and half months time is reasonable for completing part II and III with my situation. I have other things to do, so I want to prioritise taking the exam compared with other business when the extra cost is taking place for the certificate after 1st August.

Thanks in advance!
