* I am sure we both agree on the certification study journey and knowledge gained being more important than the end certificate (except perhaps the certificate is needed for job interview or OPN partner points)

... IMHO it may a have little value to some
[1] ... they can still say exam passed on CV .... maybe that helps get a job.
[2] it is chance to gain experience of certification exams ... 1z0-047 is a tough introduction to certification exams.
[3] It is a chance to get a quicker certification exam 'win'
[3] It is a cheaper exam (as it it online available and not 'high stakes' ... ie does not give a certifcation by itself).
.... 1z0-051 is about 2/3 the cost of 1z0-047
But I am willing to accept this is a perhaps a small set of positives; and thier may be no point for many.
I really don't like the fact that anyone wanting an Oracle (Enterprise Edition) SQL certification (without PL/SQL) has to go for SQL OCE. An earlier certification would be better.
I generally like the CIW Database Design Specialist: (Exam 1D0-541) content .....
I would certainly modify my earlier idea of 1z0-047 having as a pre-requisite an earlier SQL exam / certification as a pre-req ....
And would certainly have 1z0-051 or CIW Database Design Specialist: (Exam 1D0-541) on the pre-req list ...
( There are precedents for non-oracle exams/certs being acceptable in lieu of an oracle exam .... eg LPIC-1 for 1z0-402 )
( There is however IMHO no precedent for an OCE exam having another exam as a precedent ).
.... Apologies to original poster .... I may have sidetracked your orginal question with a slight debate.

  • WHAT ARE THE RECOMMENDED CERTIFICATIONS FOR A SOFTWARE DEVELOPER?

    HI FRIENDS COULD SOME ONE HELP ME OUT WITH THE LIST OF RECOMMENDED CERTIFICATION FOR A PROGRAMMER. TO GIVE YOU AN IDEA OF MY WORKING PLATFORM. I WORK IN C/C++ AS FRONTEND WITH UNIX AS BACKEND. I ALSO DEAL WITH UML AT TIMES. SO DO PLEASE HELP ME OUT TO SPOT THE EXACT CERTIFICATION WHICH WOULD HELP ME IN MY CARRIER.
    Edited by: user11087237 on 20 Apr, 2009 9:43 PM

    You can get an OCP (Advanced PL/SQL) by completing 1z0-146. You have in practice to get PLSQL OCA first.
    You can also get OCP via a forms route instead .... 1z0-141. What I am trying to say is Oracle has a number of products other than sql* Forms, and forms may be in decline, so if you are not already familiar with forms that may not be the best place to put efforts.
    What I was trying to say that is possilbly that effot getting to know apex (application express) may be better than time spent trying to ge to grips with and certifiying in Forms. (Though as far as I am aware there is no apex certification).
    i feel that you suggest me something other than oca /ocp certification. if i am right do please clear me out . and for your information i have worked in sql & plsql for quite a good time.In summary
    I am suggesting you seriously consider Oracle PL/SQL Developer Certified Associate(OCA) and Oracle Advanced PL/SQL Developer Certified Professional (OCP).
    However the case for studying for (Oracle Forms Developer Certified Professional (OCP)) is perhaps less clear cut if you have not aleady got forms experience, and that for you effort may be better spent elsewhere, possilby even in non certified study (jdeveloper, application express, oracle designer ... )

    Hope that is less unambiguous.

  • Good Resource for Finding Java Developer for Startup?

    Not sure if this is the appropriate to place to post but we are looking for an interested Java developer to come onboard our very small (2 man) startup to help us with our networked Java application.
    I have looked around a little online and not found much so does anybody know where is a good place to scout out such persons? Admittedly we are not flush with $ but we do have some and we would be providing equity along with ongoing cash payment. Of course we also understand we won't be getting the best Java guru out there but then we don't really need that either, just someone capable of simple socket programming, swing and basic SQL stuff. Not rocket science, and we would even consider less experienced developers with a keen interest to learn and use this as an opportunity to develop some new real-world skill so their own. We are very laid back.
    Any help appreciated.

    I'd try one of:
    Your local Entrepreneurs meetup
    - there's bound to be one, and people who go along to this sort of thing will either be able to recommend someone or you might even meet the right sort of Java dev there.
    The Joel On Software jobs board
    - because the right sort of people read Joel On Software
    Personal recommendations
    - because that's always best; if you're not asking around like crazy, you should be.

  • Need suggestion for choosing Java development enviroment

    Hi Evereyone,
    I am new to Java Desktop Application.I need help on choosing proper Java technologies and development tool.
    We have an existing CLIENT/SERVER based distributed control system, which was developed in C++(Server side) and VB(Client GUI).Now we are think of migrating the system to Java platform.
    Here is the outline:
    We want to create web based application that will run on windows and linux (linux on embedded PC).
    The application should be able to support 10 � 100 users at once accessing/editing database.
    We will also need to create a communication server that will run on web server P.C. that will communicate tcpip to field panels/log to db, as well as allow web screens to send/receive commands with field panels etc.
    Could any one give me some suggestion about it?
    I am thinking of Using J2SE 5.0, including RMI, JDBC and Swing for GUI. As for field panels, may choose J2ME.
    Thank you very much in advance.

    Thanks, zadok .
    Actually, I don't have the system requirements neither. All I know is the following outline:
    "We want to create web based application that will run on windows and linux (linux on embedded PC).
    The application should be able to support 10 � 100 users at once accessing/editing database.
    We will also need to create a communication server that will run on web server P.C. that will communicate tcpip to field panels/log to db, as well as allow web screens to send/receive commands with field panels etc."
    It is a interview question, which need me to do research and give some suggestions. What I want to know is to figure out what kind of Java technology is necessary for developing this system because I want to make sure I head to right direction.
    I know somehow it is hard to give suggestion based on this limited information.
    One more thing I was confusing is the server-side architecture.
    I need suggestion about sever side architecture:
    a. write a dedicated server-side program, which act
    as communication server to monitor and control field
    panel, also act as server-side applicaiton by using
    RMI to communicate with Client-side communication.
    b. choose a general web server architecture. Put
    everything in server side in Web Server, for example
    Tomcat AS container, implementing the Communication
    server as Web Service and the request from
    Client-side go to Web Server first, then dispatch to
    a proper web service.Why did you not include this information in the original question!
    Why don't you just use Tomcat?
    For your answer, "Why don't you just use Tomcat?", does it mean Tomcat without Web Service will be enough for this system development? Could you give me some detail about it?
    Thank you very much, zadok.

The best place to know that is SAP Education. You can get the mailing link from sap.com --> services --> SAP Education.

  • Certification for WEB COMPONENT DEVELOPER FOR J2EE[tm]

    Hi all,
    I'm thinking of getting certified as a
    WEB COMPONENT DEVELOPER FOR J2EE[tm] PLATFORM.
    What is your experience? How do I prepare best for the exam?
    Any book / tutorial particulary useful?
    Thanks for your input!
    Anja

    For what its worth, I found this the easiest of the certifications (compared to Programmer and Developer). My 2 cents of advice includes:
    - Use the Sun objectives as the driver for your study. Review the objectives thoroughly and make detailed notes by section. http://www.javaranch.com/scwcdlinks.jsp has some good examples of this (plus a lot of other useful stuff). The exam is a bit of a memory test - you need to know details of the deployment descriptor, the taglib definition, listeners, the API etc.
    - Take the time to read the servlet and JSP specifications. Although on first sight these are large documents, much of them is reference material and they can be read in a couple of hours. They will help in making the detailed notes.
    - Go over the servlet API for the key methods.
    - If you've not been working with servlet/JSP technologies, read a good book on servlets / JSPs for general background.
    - Try a few mock tests, although there are far fewer available than for JCP. Avoid the ones that charge a fee - I found them less than helpful.
    - This is probably just me, but be careful if you book the test via the web. I did just that, and when I turned up at the test center they had never heard of me. Follow-up with a phone call to the actual center to ensure that they are expecting you.
    Good Luck!

    I was wondering what is the education level of most Java developers. Do you have a SCJP ceritifcate? What degree did you get in college?
    Just curious.
    Cheers.

    For myself, I have a BS degree in Computer Science. I have been working as a developer for 5 years. I started as a VB programmer, and the past 2 years have been doing Java programming. I am currently studying for the SCJP exam and thinking about working on a Master's Degree in Software Engineering. The University of Maryland has a good online program.

  • Posting for non-java development?

    Greetings,
    I'm not having much luck with the forum and I was thinking it may be my selection of forum area to post in. I'm currently developing in C on an E25K running Solaris 10. I'm trying to write high-performance code to take advantage of my environment and I need to know where I can post questions about topics such as threading, memory use, the vm system, disk subsystem, etc..
    I'm not looking for answers to questions like "how do I make a thread?", but more along the lines of "when does the vm system start to discard pages of a mmap'd file that was advised of sequential access?"
    Thanks for the help, any pointing in the right direction would be greatly appreciated.
    Matthew

    Well, I do try to write good posts, but I suppose that is subjective. Also, sometimes the problem is complex and will take an iterative conversation to come to a resolution or useful information.
    I do a lot of RTFM'ing and can usually find solutions to specific problems (2 + 2 == 4, etc..) ;-) However, recently I find myself needing to understand some things that would require a bit of low-level knowledge of the kernel or disk layer, etc.. Yes, the Solaris code is open and I could read it, but time is a factor, as well as the ability to actually understand such code as the VM paging system, for example. I think I'm a good programmer, but not that good, yet...
    I see a lot of unanswered posts in the forums so maybe the community is simply too small for the topic? Or does everyone pay for their support, thus making the forums less of a resource? I was surprised (in a good way) that Sun sells developer support for only $500 a year; IMHO that makes it available to many software developers. However, in my situation I'm not willing to pay out of pocket when the company I work for could easily have such a contract with Sun (but they don't). Thus, I'm trying my only other option, these forums.
    Thanks for the feedback. I'll try to write better posts.

  • Performance Tuning Certification for Application Developer

    Hi,
    Can you please advise if there is any Oracle Performance Tuning certification for an Application Developer and Oracle 9i to 10G migration certification? If yes, can you please let me know its Oracle examination number?
    I have already passed 1Z0-007 and 1Z0-147 in Oct 2008.
    Thanks in advance,
    Sandeep Kumar

    ... if there is any Oracle Performance Tuning certification for an Application Developer ...There is no performance tuning related certification for application developers. There is one for the DBA track.
    Also -- to answer your question in the other thread:
    So to clear this certification do I need to re-appear all the 3 exams as they were given in 2008 or just 1Z0-146 is enough.Having passed 1Z0-007 and 1Z0-147, if you pass 1Z0-046, you will gain the certification: Oracle Advanced PL/SQL Developer Certified Professional

  • Flex for Java Developer?

    I am working on flex 1.5 from last 7 months.Ealier i hv

    I hv created an application in flex sucessfully.
    My Qtn is:
    Whether i have to continue with flex or move to another
    technologies like Struts etc.
    Because i have nil knowlwge of FLASH.
    or
    I hv to start learning FLASH MX. Is it necessary for

    Please Suggest.
    with Regards

    well vinay if u r thinking about -- Flex Front End to Your
    Struts Applications
    then ,,
    Struts is an open source framework that facilitates the
    development of web applications based on Java servlets and other
    related technologies. Because it provides a solution to many of the
    common problems developers face when building these applications,
    Struts has been widely adopted in a large variety of development
    efforts, from small projects to large-scale enterprise
    applications.
    Although Struts greatly facilitates the task of developers,
    it doesn't do much to improve the end-user experience: the
    end-result is still an application delivered in HTML and using the
    traditional HTTP request/response mechanism.
    Developers—and organizations in general—are
    increasingly looking for solutions to provide their applications
    with a more engaging user experience that overcomes the limitations
    of HTML.
    Macromedia Flex is a presentation server that addresses this
    requirement and allows developers to build a new generation of Rich
    Internet Applications (RIAs) that combine the usability of desktop
    applications with the reach of traditional web applications.

    Yes, that did work. I casted my event into a LinkClickEvent and then was able to pull out the id of the link that was clicked. I tried the getRef, getAction, and getComponentName methods. The getComponentName method gave me the name of the link that was clicked. The getRef method returns null, and the getAction method returns what's listed between the double quotes after onClick in the jsp page:
    onClick="contactLinkClick"
    So, in other words, getAction returns "contactLinkClick".
    Here's what my onContactLinkClick method now looks like in the dyn page:
    public void onContactLinkClick(Event event) throws PageException {
         LinkClickEvent l = (LinkClickEvent)event;
         String ref = l.getRef();
         String action = l.getAction();
         String compName = l.getComponentName();
         System.out.println("ref = " + ref);
         System.out.println("action = " + action );
         System.out.println("compName = " + compName);
         nextJSP = "ContactDetails.jsp";
         }     // end method onContactLinkClick
    Now I'll be able to grab the id of the link that was clicked and therefore the id in the arraylist of objects. Thanks for your help!

  • Some basic questions on Java development and NetWeaver CE

    Hi there,
    Can someone please explain for me:
    1. What are the development tools that will help me do Java development in SAP?
    2. Can I use non-SAP Java development tools (e.g. WebSphere or Eclipse) to develop custom extensions?  Are these equivalent to the functionality provided by CE?
    3. Given the options for doing Java development in SAP, are there any situations where I would need to do custom development in ABAP? (Is the Java functionality equivalent to the ABAP functionality?)
    4. Is NetWeaver CE only meant for Java development, or can it also be used for ABAP development?
    regards,
    Eric

    Hi
      for Java development you can user Eclipse or NWDS , which are both and the same .
      And about the ABAP development in CE 7.1 in the developer studio is it not possible .
      you are allowed for the java development .  And about using Non-SAP java development tools
      you can use the tools for java development , may the UI building ..... has to be build  when compared to
      CE 7.1  developer studio

  • Oracle database 11g certification for Java developer

    Hello,
    I'm Java developer, OCPJP 6 ( Oracle Certified Professional, Java Programmer +6+ ) and
    I decided to pass exams: 1Z0-051 and 1Z0-052 to get OCA ( Oracle Database +11g+ Administrator Certified Associate ) certificate,
    but I need some advice, maybe i should seek other certificate, that would be more valuable for Java developer, than OCA.
    Thanks for advice.

    The answer of whether a particular certification is valuable depends on you, not the tests themselves. The Oracle Certified Master for example is an extremely prestigious certification, and I have considered seeking it at some point in the future to improve my professional credentials. However, the same certification would have absolutely no value to my wife, because she's a homemaker with no interest or intent of ever working with Oracle.
    Using an example a little closer to yours, only reversed --- I work as a DBA and PL/SQL developer. On several occasions I have dabbled with Java, and took a couple of classes when I worked for Oracle. I could code in Java if I had to, but wouldn't really be good without a lot of practice. However, I've never really had a sufficient need in my work to dig in and really practice enough to use it. I considered going for the Oracle Java certifications as a means of kick-starting that and getting to the point where it was really a viable option in my development. Ultimately I decided not to because I've been working with Oracle for better than fifteen years and there has never been an occasion where I really felt a need to know Java. If I were to spend a bunch of time improving my Java skills just for the certification, there's no guarantee I would ever use them after that.
    Coming back to you -- if you already need SQL and DBA skills in your work, then those certifications should be of value to you immediately. If you think that you might work (or want to work) more with SQL and DBA-level skills in the future, then they should be of value to you in the future. If you won't use the skills now or ever, then the exams do nothing but add a line to your resume (which still has value, but you must determine how much).
