CONGRATS!!
Though not the last one, my address is johnysamca@yahoo.ca

Hi Omar,
The Design Pattern site that you have mentioned, Is that enough to understand the design patterns for the exam? Or does it need more reading?
Your reply is appreciated.
Thankx.

Omar,
Could you please send me the documents to this email address: johnysamca@yahoo.ca
Very many thanks.

Hi Omar,
You said there are two good documents that you found on the net, to study for part 1.
Could you post the "links" for the documents, if not we do not know how to attach.
Thanks in advance.
Also, I would like to know, does the wrong answers in the exam carry negative marks?

The objective says the duration of SCJA part1 exam is 75 mints.
Is it 90 or 75 minutes?
Thanks.

Thanks Adithya.

To the guys who have appeared Part1 exam:
Is it possible to skip the question unanswered and come back to the same question after answering few questions?
Is there any 'icon' in every question page to check mark it, to review or to answer later, that particular question at the end?
Can some one experienced help on this?
Thanks.

I just cleard from the Blue Print. The lower the isolation the greater the concurrency.
So the answer must be B.

When two programs are running concurrently,
how can it be read uncommitted.
If there is no concurrent transaction, this is the best one to assign to improve performance.
The answer should be read committed, I mean C.
Am I right? Awaiting reply.

You are right. Both 2 & 3 seems to be the right answers. The problem is if the question is asked to choose the best answer.

Advantage of intranet is:
1.Low bandwidth
2.multi Web servers
3.multi-level access to resources
I think the best answer is 3.
Could anyoneconfirm this?

Thank you so much for clearing my doubts with DAO &VO.

What design pattern does the Data Access Object & Value Object match to?
Can some one help !

I do not think the answer is convincing.
It is not executing the uncommitted data.
Or, by default could it be READ_COMMITTED. HELP???

Thank you so much. Shall we go to the next clarification?
Your J2EE solution that you implemented has been a huge success. The number of customers is almost 5 times what has been anticipated and performance is becoming an issue
(select the best two)
1) Add more RAM to the 4 processor 4GB RAM Appserver
2) Add another AppServer set the webconnector to round-robin
3) Add a second network (LAN) card to the web server
4) Upgrade the database hardware
I feel the best answers are 2 & 4. Am I right? Help...
