I have made the same assumption and slightly updated physical domain model. I will let you know if I pass ;)

Folks I passed in Oct2011 with WPC. I did make subtle changes to domain model but made appropriate assumptions and documented them as well as the changes. Don't worry this is what an architect faces in reality.

Wherever possible component dependency should be shown by required and provided interfaces i.e. sockect and bubble notation. That makes a component isolated, replaceable and independent. I think <<uses>> notation is just a work around when we do not have clarity on specific interfaces within a component.

Just my opinion.

I got my success kit in 2 weeks too. But the problem is I can't see any details on CertView site and I can't download the logo. Any ideas what could be the issue? I have updated my details on both oracle and Pearson site.

I got email from Oracle yesterday informing SCEA success. I had submitted WPC assignment on 18th Jul.

Took about 11 weeks wait.

All the best to all the aspirants and thanks to all the ranchers here for all the help.

Yes. I had WPC assignment. Completed part3 on 18-Jul-11. Got passed email today (finally). More than 11 weeks wait.

Would you mind telling us which assignment did you do? Thanks

This will help me decide on my assignment too.

Thanks in advance,

I updated my domain model slightly and added it submission under the class diagrams I had created. I called it Physical domain model.

Mind you I am still waiting for the results

Congrats.

It seems 10 weeks is the current timeline.

Those of you who heard their part2-3 grading results recently, can you share the timelines please? How long did it take to grade.

Cheers.

Having a singleton instance is as good as suppressing the need for clustering for Timer based business logic execution, especially if all the cluster member share the same database.

There are many ways to tackle this issue based on the business requirements. For example if a scheduled job is billing the customers everyday whose bill is due on that day, the timed SLSB can be configured to process only a set of customers. Hence divide the workload (Customers by region,tariff etc.) amongst cluster members. In this case clustering would complement the improved performance.

But at the same time if you have lots of timer based stuff, then clustering may not be a good idea at all unless each member uses its own database.

All in all I would say, take an approach that suits well to your business requirements.

I think you need to use oracle testing id in the jar name. Eg. SCEA-AAAAAAAAA.jar where 9 characters are oracle testing id. You can see that on your Part1 score report.

I look at SCEA as more of a bench marking activity of one's design and architecture skills. I can hardly remember I have used pure JEE in any of my recent projects.

The JEE6 thing sounds more of a catching up exercise in order to include good features already available in open source frameworks.

My opinion is a good architect will hardly ever follow a pure JEE stack.

Hi Roberto,

By opening this topic, you actually reminded me of the same issue I have left unaddressed in my solution which I have already submitted unfortunately.

I am using a TimerService and a Timeout method on a SLSB which is going to be deployed in a cluster. At the back end side it obtains some data from DB and saves some data back after executing business logic. Optimistic locking on JPA side will avaoid any data issues cropping up but I think I should have written a line or two in assumptions about this.

Its better to look at objectives first which may give clues.
