so I found that quite disappointing as I like to study in mobility my Spring 5 exam



Hi Mike,

If you have internet connection on the move, you can use itestjava on your mobile browser.  It is responsive and the page will adjust based on the size of your device' screen.
The Pivotal guides for the Core exams  (4.2 to 5) are currently at:

https://pivotal.io/training/certification

I noticed that React* is not in the Spring guides above, for 5.0.  There are A LOT of topics not in the exam.  I suggest that you refer to the guides so as not to waste your time studying the wrong topics or topics not in the exam.

There are practice tests here below for 4.2 and 4.3:

I am still currently completing the one for 5.0.

Cloud Foundry was created by the company behind Spring/Spring Boot.
You can audit a course on this topic for free at https://www.edx.org, but if you want a badge for your Linked In/CV then you need to spend money.
Cloud Foundry also has a certification path which cost money.

In addition to or perhaps in contrast to Cloud Foundry, you may want to know about AWS.

I'm unsure if you have mentioned anything regarding databases. You may want to know at least the basics of either SQL and/or NoSQL systems.



Yes, I have personally benefitted on certifications.  Thank you for the tip.  I will keep Cloud Foundry in mind, as it might also have better easier integration with its brother the spring framework.

AWS knowledge is probably essential, as many companies use it.

For DB, for Spring Cloud Config, we can use Redis, etc. 

I still have to look at NoSQL systems.  Regardless, Spring Data definitely will be there to help, as usual.

Agreed.  Most of the other technologies I mentioned is to implement the good case scenario of easiest effort from all involved:  architecture, developer, devops.

Devops is assisted most by using images like Docker, and continuous integration/deployment tools like Travis and Jenkins.

I just read Spring Microservices in Action, by John Carnell.

Docker, Hystrix, Ribbon, Eureka, Spring Cloud (Config, Stream, etc. etc.), Maven, Spotify, Zuul, are some of the technologies that come to mind quickly that were mentioned and used.

To those who are actually working or have worked in microservices, what technology did you use?

The 1z0-051 is required if you need to get the related pl/sql certifications  (11g).

There is still a huge number of global institutions using 11g.  This is probably one of the reasons why some people are still focused on getting 11g certifications.

But if you havent started studying for 11g, I also agree that you should focus on 12g 1z0-071 instead.
This was an old post, but just in case someone needs to ask the same question, there is a free practice test, using promo code JAVARANCHFREE at:

Hi,

I am looking the exam/exams, which has available study guides  (e.g. books targetted at the cert), and mock exams.

I can do either Oracle 11 or 12.

Which exam/exams do you know has sufficient book/study guide, AND mock exam, out there?

e.g.
--------------------------
Oracle Database SQL 1Z0-071
Oracle Database 11g: Advanced PL/SQL 1Z0-146
Oracle Database 12c: Advanced PL/SQL 1Z0-148
--------------------------

I researched by it seems the exam for Oracle 12 has lack of supporting books/mock exams out there. 

This is what I found so far:

transcender has
   practice test
      1Z0-071 - Oracle Database SQL (OCA) Practice Exam
      1Z0-146 - Oracle Database 11g: Advanced PL/SQL (OCP)
www.oraclecertificationprep.com has
   study guide
      Study Guide for 1Z0-071: Oracle Database 12c SQL (kindle)
   practice test
      1Z0-146: Oracle Database 11g: Advanced PL/SQL
In addition to what has been mentioned already, have you considered mobile applications, front-end applications on the browser  (like those using angularjs), etc.?

Hi,

'2-way' means (synchronous, like calling a method, or remote procedure call).
I send a message to queue 1, and in few seconds (10 second limit), I must receive a reply to the message at queue 2 (sent by another service as reply to my message).

SEND.
Because the 'send' part must be committed (transaction), so that message will be sent and receiver can retrieve the message, then there is no need to put it in a transaction. Is this correct?

RECEIVE.
In the 'receive' part, if and only if my business requirement never needs me to put back a message into the queue (e.g. failed processing), then I do not need to put it in a transaction. Is this correct?

SUMMARY.
Because in my business requirement, the 'receive' does not need to put back the message in any scenario, then I dont need to put neither the 'send' nor the 'receive' in a transaction. Any comment, e.g. if this is bad?
