For an SAP enterprise(4.7), how to add java stack during upgrade to ECC6.0?

Source release:  an R/3 4.7 32bit
Target release: ECC6.0 64bit (abap+java)
My plan is to go over the following upgrade steps:
4.7 32bit-> ECC abap only 32bit ->ECC abap 64bit -> install java stack.
Is this the best way?
Thanks a lot!

Hi,
Its always best to go to the enhanced and latest version.
_+4.7 32bit-> ECC abap only 32bit ->ECC abap 64bit -> install java stack.+_
the above step will increase only only the cost.
If ur going for just practice purpose, then no issues u can go for it.
But its always good to go for
4.7------> Ecc(ABAP + JAVA) together.
coming to 32bit and 64 bit. Some constraints are there. If u look at Ecc 6- SR3, it will only support 64 bit.
Look at all those sections and go for upgrade.
Regards,
Ravi

  • How-to remove java-stack

    Hi,
    is it possible to remove a java-stack from a central instance? For example a CRM installation, having both abap and java stack?
    The java-stack is not used.
    Toine.

    Hello Toine,
    Yes, it is possible to remove the java stack. You can find the information how to do it in the WAS installation guide of your release, under a section "Deletion of an SAP System Installation (J2EE)"
    Kind regards,

  • How to add Java projects to FlexBuilder2?

    In a recent
    Breezinar about
    Flex Data Services James Ward demonstrated how to to debug a
    Flex2/Java application by simultaneously setting breakpoints in
    both the ActionScript client and in the Java server from within the
    same instance of Flex Builder 2. The out-of-the-box FlexBuilder2
    doesn't have a Java project type. Anyone know how to add Java
    support to FlexBuilder2 to support the Java+ActionScript
    development environment demonstrated by James in his Breezinar
    ?

    When installing Flex Builder, select the option to install
    the Eclipse plugin
    version instead of the standalone version. The standalone
    version can only
    work with Flex projects, but the Eclipse plugin version
    *adds* Flex to
    whatever your existing Eclipse installation has (typically
    Java).
    A screenshot of what I'm talking about:

  • I need help for my fading out,in animation : how to add a link to your animation ?

    i really want to know how to add link to your animation .
    well when i passe the mouse over my animation it stops and when i leave it the animation continue... but what i want when the mouse over the animation i want to click on the animation and to bring me to a link.
    here is my code and i will really appreciate any help ... thanks so much in advance.
    function stopFade(event:MouseEvent)
    container.stop();
    function resumeFade(event:MouseEvent)
    container.play();
    function aller(event:MouseEvent)
    getURL(www.google.com);
    container.addEventListener(MouseEvent.MOUSE_OVER,stopFade);
    container.addEventListener(MouseEvent.CLICK,aller);
    container.addEventListener(MouseEvent.MOUSE_OUT,resumeFade);

    It appears you are mixing different versions of actionscript, which you cannot do, and I am surprised you are able to get the file to run without error messages.
    Change...
    getURL(www.google.com);
    to
    navigateToURL(new URLRequest("http://www.google.com"));

  • How ABAP and JAVA stacks are connecting

    Hi Experts,
    I have a doubt in pi. We are developing Message Mapping in IR, it means it is running on JAVA STACK. But we are checking any mapping error in SXMB_MONI which will run on ABAP STACK.
    Now My doubt is " How JAVA and ABAP stacks are connecting to each other and How we are able to see Mapping error in Integration Engine which resides on ABAP stack even though we create Mapping in IR which runs on Java".
    Thanks&Regards ,
    Gajapathi.

    Hi Gajapathi,
    How JAVA and ABAP stacks are connecting to each other
    PI manages using single database for both JAVA and ABAP servers. But both access them using different schema. They connect using RFC protocol via SAP Java Connector (JCo Connector).
    How we are able to see Mapping error in Integration Engine
    which resides on ABAP stack even though we create Mapping in IR which runs on Java".
    So when you create a object be it mapping or interface or any XI objects, it is stored in Single Database. When you use ABAP sxmb_moni for monitoring the message, it uses ABAP related schema to access the message.
    I hope it answers you query.
    Regards

    Hello
    If you are adding XI 7.1 check this page: http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000702775&_SCENARIO=01100035870000000202&
    If you are adding XI 7.0 check this one: http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000659894&_SCENARIO=01100035870000000202&
    You should read the master guides and install the new usage type on top of your current installation but check the SAP notes about it first.
    If what you want is to install XI 3.0, that is if you have an existing v6.40 java stack, I think the operation is not recommended/supported by SAP, you should install a separate instance.
    Hope it helps.

  • How to view java stack "systemINFO" in R3 GUI?

    Usually we go http://host:port/index.html , select "system information", then see the java components applied to the java stack.
    Can the same system info be found in some DB table so that we can view them via se16? Or are there any transactions show the same system  info?
    I ask this question is because sometimes I do not have the administrator ID or sometimes the java stack has trouble to be up.
    Thanks for your help.

    Dear Sunny
    You should be able to see them in your Solution Manager SAP system in transaction SMSY.
    or
    You can connect to the Java database schema using a third party tool (database viewer) to view the tables. You can easily find freeware software.
    However you do need the connection string and user/pass of the target database to be able to connect.
    Kind regards

    Hi,
      You can apply stacks when server is running. Make sure server is up and running. You can then start installing the stack 13 directly. (No need for 10, 11,12 etc).

  • How to restore Java stack

    Hello.
    How can i restore Java stack from 11 levele to level 4 ?
    regards,
    Denis

    Hi,
    As for as I know, you cannot downgrade from higher SP to lower SP through any means like JSPM or SDM or any tool.
    It you want to move back to SP4 ,then only solution I know is to install a new server with SP4 afresh.
    Hope that helps
