First of all thanks for the forum.
After having 10 years of experience in JavaJ2EE and related technologies.
I've decided to start certification. Till now I do not have any sort of certification.
I've just started preparing for 1Z0-808 (OCA). And Enthuware mock tests.
Completed reading through the book OCA Java SE8 Programmer I Study guide from Jeanne Boyarsky and Scott Selikoff. And Its really good.
I wanted to do Java Architect level certification. And the path from oracle website is little confusing.
Can some one please guide me through the right certification path.
Java Architect certification does not have any other exams pre-requisities (e.g. Java Programmer), like most other Java certifications (e.g. Web Developer, EJB Developer).
You will not see any single line of code on the Architect Exam, learning Java syntax is not essential.
What is really asked - high level knowledge of many Java EE technologies and advantages/drawbacks between them.
This is for Part 1.
Part 2 is application designing assignment, here only your experience + UML knowledge is required.
Part 3 is a proof that you did assignment - answering generic questions about your design decisions.
Plus you need to take an eligible training.
So, it's up to you to start with OCA JP, but then if you want to take Java EE exams (EJB, JPA, Web, WebServices) which may help for Architect Exam, you have to take OCP JP first. Not sure if this is your plan.
Further to MZ's comments, the architect part 1 MC exam basically expects you to know what it's for (purpose), when to use it and why. Besides the technologies, design principles, patterns, security, interoperability are also needed.
Parts 2&3 is the assignment/essay putting your experience to use. Do note that the assignment/essay together has a 6 month time limit from assignment purchase.
All in all, a lot of reading is expected especially on those topics you seldomly use or heard of.
