  • Basic difference between WAS and Netweaver

    I justwant to a know a basic fundamental question. What is the basic difference between web application server and Netweaver. I am always geting confused in these two terms. Can anybody please explain?

    Hi,
    NetWeaver is:
    An application and integration platform that unifies people, information and business processes
    New technical foundation for all future SAP applications
    A replacement for BASIS framework
    A platform that is based on Enterprise Services Architecture (ESA); SAP hopes to release future product offerings in compliance with ESA
    NetWeaver is NOT:
    A product or a language
    A replacement for SAP R/3!
    A marketing strategy
    The SAP Web Application Server is the technical platform for SAP NetWeaver, providing the complete infrastructure to develop, deploy and run all SAP NetWeaver components, the mySAP Business Suite, customer- developed applications and 3rd-party J2EE 1.3 compliant applications.
    SAP Web AS fully supports both the proven ABAP technology and the open source internet-driven technologies—Java and Java 2 Enterprise Edition, also called J2EE.

  • Whats the difference between arrayCollection = null and arrayCollection.removeAll()?

    Whats the difference between arrayCollection = null and
    arrayCollection.removeAll()?

    In arrayCollection = null; statement you're setting this
    reference to null and potentially making it available for garbage
    collection. I say 'this reference' and potentially because, as you
    may know, there might be other references to this array collection
    object that won't be affected by this statement and hence it won't
    be GC'ed.
    arrayCollection.removeAll() says that I want to empty this
    array collection for all the reference that we pointing to it. That
    is, remove all the objects from the collection -- and of course
    make them 'potentially' available for the GC -- the size of the
    array collection would be reduced down to zero and all the
    references would be pointing to a valid but empty collection.
    Hope this helps.

  • In ical, how can you tell the difference between a meeting invite and email?

    When you send a meeting invite in ical, does the recipient receive a different icon in their inbox to differentiate from an email?

    For service stock you can't tell the difference between a new iPad and a refurbished one. Both will come in a plain brown box with the same pattern in model numbers. If you mean between a refurbished one and one new at retail, then other than the obvious difference in packaging, I've read that the model number on refurbished units starts with the letter "F", though I've not confirmed that.

  • Any basic differences between AT&T and Verizon, & other questions

    I am thinking of buying an iPad mini with retina display (32gb). This would most likely be the only iPad I would ever own. I would use it mostly at the house with wifi, but would like to have one with cellular for when we travel in the US and Canada, and for when the electricity goes out. We currently live in a location where both AT&T and Verizon are viable options, but sometime in the next year we hope to move. The state is rural and mountainous, so as we drive around, my spouse's iPhone (with an AT&T plan) often loses service, but so does my Jitterbug phone, which is not tied to any one carrier (as far as I know). A phone can get a signal in one locaton, but then lose it a few feet down the road. So, there is no way I can choose between AT&T or Verizon based on coverage because both are options right now and there is no way to predict which one(s), if any, might provide service to wherever we end up moving to. Therefore, I'm wondering if there are any basic differences between AT&T and Verizon (or any other of the possible carriers) in what they offer or how they work or what they charge and so on that can help me decide which one to choose since it is my understanding that once I pick one of them for an iPad, that decision can never be changed without purchasing a new device. (e.g., I had read somewhere that Verizon does not allow for voice and data at the same time, but since an iPad is not a phone, is that even an issue?) Also, will the iPad work if there is only regular 4G or 3G service? And will a cellular iPad work without signing up for a data plan since I expect to start with only wifi and then add a data plan later? Thank you.

    Alfred DeRose, Thank you for answering the second and third questions. Judging by what you wrote, I am assuming there are no differences between what AT&T and Verizon offer that affects iPads, other than looking at coverage area and the cost of "pay as you go" plans. And, as noted, coverage is not something I can base a decision on at this time. So, I either flip a coin to choose between AT&T and Verizon and hope the result is the right one after we move to wherever we end up finding a place to live, or I continue to wait for another year or more until we actually find a new house before I buy an iPad (or maybe a Kindle Fire HDX 8.9"to save money, but I think I've probably settled on an iPad mini retina 7.9" despite its smaller screen). That does not move me along the decision-making process at all, but it is what it is.
    Greatcall has not answered my question about what carrier(s) the Jitterbug Plus phone uses. If, in fact, it uses just the Verizon network, I will try to pay better attention to any possible differences in service areas between that phone and my spouse's iPhone as we travel around the state to see if that helps at all. But coverage is so location specific here that I don't think it will.

  • Pls tell me difference between case and decode

    Hi all
    pls tell me difference between case and decode
    regards

    Well not entirely true when you consider working with
    sign and decode together. Your example could be
    written with decode and sign like this:
    decode(sign(sal-1000),1,sal+comm,-1,sal,0)But the case expression reads more easily, I admit.Rob it was just example you considered it special case ,BTW can you do it for me by DECODE function.
    SQL> SELECT sal,comm,CASE WHEN sal>1000 AND sal<1300 THEN sal+comm ELSE 0 END

  • Can anyone tell the difference between USB 3.0 and 2.0?

    I have both a 8GB flashdrive 3.0 and 2.0. I got the 3.0 at office depot for $8.00 and 2.0 for the same price at best buy. I honestly can't tell the difference between the two. They both seem to be the same in speed. Is there really a difference?

    This is an interesting subject, I just recalled a MacWorld podcast I was listening to when the 3.0s were first hitting the market. A guest on the podcast was saying to think of it like a 'bottle neck' not so much as speed. With the 3.0 you can push more information through at any one time. So in the case of the hd movie senario, if you had multiple movies transfering at one time the 3.0 would be a lot faster than a 2.0.

  • Basic differences between G2 and G3

    hey, is there a breakdown anywhere of the basic differences between G2 and G3?
    i've tried looking but everything i've read seems to single out the podcast features of g3 which to be honest, don't really do much for me, since i would be using it mostly for music.
    Are there substantial differences aside from the podcast features that would justify the upgrade? and if so, any idea where i can read about them?
    thanks in advance.
    G4   Mac OS X (10.4.6)  

    there also some more differences as compare to gb2 is the ability to do music composition for your edited imovies and one more thing if you change your track to sound efxs you can drag audio files into your onscreen keyboard or your musical typing on your assign key to do music composition which gb2 dont provide last time.

    Nothing definite, but http://mindmachine.co.uk/products/HP_Texts/HP_LJ_Pro_M1130_01.html suggests that:
    The MFP1132 (part number CE847A) is for  American and European markets, and uses the CE285A toner cartidge.

  • How to tell the difference between 10w and 12w?

    We have:
    2 iPhone 5s
    1 iPad
    1 iPad 2
    1 iPad (4) with Retina
    I know that the iPhones use the smaller 5w charger, but how do I tell the difference between the iPad/iPad 2's 10w charger and the iPad 4's 12w charger? They look exactly the same.
    The iPad 4 takes forever to charge, so I want to make sure I am using the 12w - and I don't want to damage the older iPads by accidentally using the 12w.
    Thanks!

    Read the fine print on the charger. My iPad 2 10W charger says 5.1V 2.1A. A 12W charger should have a higher number for A.
    You can use the iPad 4 charger on your other devices, without damage, to charge them faster.
    ~~~~~~~~~~~~~~
    The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W (5W on Mini) USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
    Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
    How to Calibrate Your Mac, iPhone, or iPad Battery

    At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.

    hi,
    like -> used for refering existing data elements in data dictionary or in sap
    type -> used for refering existing data types in sap.
    types: used for creating used defined structure of tables which has fields from more tahn one table.
    diff b/w types and type in creation of internal tables is that when u create a table with types then u can use same for work area creation also.
    ex:
    TYPES : BEGIN OF t_vbap,
    vbeln1 LIKE vbeln,
    posnr LIKE posnr,
    kwmeng LIKE kwmeng,
    netpr LIKE netpr,
    netwr LIKE netwr,
    werks LIKE werks,
    matnr LIKE matnr,
    arktx LIKE arktx,
    END OF t_vbap.
    data: itab1 type t_vbap
            wa_itab1 type t_vbap.
    when type is used then u have to create a defintion of work area for another time when internal table doesnt have headr line as
    ex:
    DATA : BEGIN OF t_vbap OCCURS 0,
    vbeln1 LIKE vbap-vbeln,
    posnr LIKE vbap-posnr,
    kwmeng LIKE vbap-kwmeng,
    netpr LIKE vbap-netpr,
    netwr LIKE vbap-netwr,
    werks LIKE vbap-werks,
    matnr LIKE vbap-matnr,
    arktx LIKE vbap-arktx,
    END OF t_vbap.
    DATA : BEGIN OF wa_vbap,
    vbeln1 LIKE vbap-vbeln,
    posnr LIKE vbap-posnr,
    kwmeng LIKE vbap-kwmeng,
    netpr LIKE vbap-netpr,

    werks LIKE vbap-werks,

  • What is the basic difference between Hyperion Planning and HFM

    Hi GURU'S,
    what is the basic difference between Hyperion Planning and HFM and when do we choose them.

    On a high level the difference is this:
    1. HFM is best for global collection (collecting data from scattered entities), group consolidation and for easily structuring financial reporting (mainly consisting of financial data)
    2. Planning is best for modeling your business, starting from a demand forecast and arriving to capacity planning and finally to financial statements, by utilizing business drivers (non-financial data like volumes, prices, productivity rates etc)
    Of course, differences may be analyzed at several levels down to technical, but the discussion may turn out to be too long, yet adding little value to the question: "when do we choose the one over the other". Bear in mind that your requirements may turn out that you need both.

Maybe you are looking for
