Is web service the right choice

Hi,
I need to supply the large amount of data (avg. million records) to third party. How can I transfer such large size data? I am thinking of using a table to hold the records keys and then using chunks of keys to query and compose data to return partial data each web service call. Any ideas will be appreciated. Thanks

You have to ask yourself the following questions before deciding whether a web service is the right solution.
Is this a one-off extract?
How often will the extract run?
Does the customer have a client capable of calling a web service?
What governance, compliance, or standards does your organisation already have?
Just how big is "a few million records"?
Does the customer need the feed/extract/data on an ad-hoc basis or only at pre-defined times?
Do you already have an enterprise environment or architecture that supports web services?
Personally, from what you've said, I wouldn't see it as a candidate for a web service. It sounds like a bulk extract sent via ftp (or similar) to an end point for a customer/system to pick up.

  • Is Netweaver the right choice?

    We have recently upgrading our portal/webdynpro server to NW 7.0 Support Stack 14 (J2EE only).  While this stack level fixed some issues that we were having (in particular cleanup of JCO pools to prevent expired SSO ticket errors) it also introduced some other problems with Oracle.  This has led us to the discussion of whether Netweaver is the right choice for our custom application development environment. I'm posting this to get some feedback on what other companies are doing with their Netweaver enviroments.  I'm particularly interested in custom application development using webdynpro and the Netweaver Portal.
    We've been running various permutations of the Netweaver platform since 2005 (BI, Portals, and now ERP).  We are using a single J2EE instance to host the SAP EP, a custom jsp "intranet", and our webdynpro apps (we have 6 custom webdynpro apps).  Our user base is somewhere between 150-250 users.  We use the portal to access these custom apps, our BW web templates, and some SAP transactions.  With the rolllout of some of these custom apps, our portals environment is now becoming mission critical and we seem to continue to have problems with the stability of the J2EE engine on the portal machine.
    Are other customers having stability problems with NW04s?  Are other customers using web dynpro and SAP's enterprise portal for Mission Critical applications?  If so, what do your environments look like?  If not, what are you using for custom applications that communicate with SAP and other systems?
    Thanks for any and all input
    Eric

    Assuming your legacy apps don't need to update the new OM system an MDB sounds reasonable. You may want to consider passing the messages as XML and using a library (JAXB/P, castor etc) for parsing / inserting into a database.
    You should also work out how to handle technical failures updating the legacy database and poison messages (i.e. when an invalid message is received). You may decided to automatically retry technical failures a set number of times before moving them to a backout queue. There's no point retrying poison messages as they'll repeatedly fail, but you may need to fix / manually insert them.

  • MacBook Air: the right choice for a College student?

    Hello there!
    I'm buying my first Apple laptop in the near future (probably tomorrow as I like to buy things in store and not online and I live roughly 75 miles from the nearest Apple store and am heading to the mall it's located in on a shopping trip tomorrow, anyway). I currently have a 3 year old Dell that has no battery life at all (it has to be connected 24/7 to an outlet, the mouse clicky button doesn't work, it overheats, and the hardrive has already been replaced not once but twice) and I don't use it for anything other than school, facebook, watching movies via netflix, skype, and listening to music. I've been doing months of research and all has lead me to Apple.
    I want this laptop to last me until I am done with my masters and into the first couple years of my teaching career, so roughly 6 years. Is that too much to ask from this machiene?
    I'm inlove with the thiness, lightness and portability of the Macbook Air. I use my laptop a lot, this semester I'm finishing out my core requirements and a lot of them are "bullsh*t" classes where I can do nothing and get an A. I would therefore have my laptop with me, I also bring it to friends rooms to study and relax. My goal is to have a laptop that I can write papers, continue to watch movies and use it as a basic machiene. I barely use a cd drive (my aunt is willing to by the drive that goes with the Air) but when I do it's just for burning music to my itunes. I want a machiene that will have a long lasting battery life - that's my biggest concern.
    My roomate has a Macbook Pro and keeps telling me that I'd hate the Air.
    I've read that people do not like it as it does not have a backlit keyboard. That doesn't bother me as my keyboard currently isn't backlit.
    I've also read that people continue to prefer the pro over the air but I am not a fan of the pro just as it is so much bigger.
    I barely ever use my USB drive, when I do its to transfer over files that need to be printed.  So having only two of them means nothing to me really.
    I'm just looking for assistance to help me make my decision. I feel like I already made it but I just want to be sure that I'm making the right choice.
    My personal pros/cons:
    Pros: lightweight, small, highly portable, amazing webcam, excellent battery life
    Cons: it's so thin I feel like I would snap it in two pieces
    Thank you so much!

    Listen to us, Lovekate!
    We know you're eager, but hold out just a little longer--maybe a week or two--for the update! Please! It's the smart thing to do because it may give you options you can use. Kate! Look away from the machines. This way! This way! You can do this. If you don't, you'll feel buyers remorse and that's not good. Hold off. You'll be happy you did...also, don't forget, when you do buy, you get a student discount.
    From what you say, you've found the computer you love and don't need any encouragement from us. But here's advise for what you can say to your friends:
    (1) To those telling you to get the Pro--you are not going to buy more than you need. With Clouds, and online mail and external hard drives, there is no need for you to haul around anything made heavy with a huge hard drive you'll never fill up. And the Air can do anything a Pro can do excepting update to a bigger hard drive (which you've just explained you don't need--like you don't need the CD drive). And the 13" actually has a longer lasting battery than the 13" Pro.
    (2) Why should you get a computer you don't love, and therefore is no fun or joy for you to work on, rather than a computer you love, which you will love working on? Apple rule, "Always get what you love." 
    (3) To your Dad, you are buying something very like a car. And like a car, if you buy one cheap, it will cost you if it breaks down, needs repairs, or needs replacing. Needing to buy a new cheap car every other year can add up to the same cost as buying a new car that will last you ten years. You are buying a computer that will last you, be reliable, and not need repairs thus interfering with your productivity (by the way, get Apple Care--adds two more years warranty for a total of 3 years--trust us on this. If you can't afford it now, you can hold off buying it till the end of the first year, but do get it!). Apple computers also have good resale value.
    In short, as much as it costs, it will be worth it.
    Hope that helps, and remember...hold out! or if you've already bought it--you have 14 days to return it.

  • Hello Everyone, I want to purchase an ipad ,please suggest whether ipad mini is the right choice to go for or not?

    I am planning to buy an ipad mini, please suggest me whether its the right choice to go for or not ?
    Hows the display?

    The Ipad 4 has a stronger processor, and better graphics and display than the Mini. but they can basically do the same things.
    Obviously one is smaller than  the other, but at the end, the games will still play on both, and you may not even notice a difference.

      (when the language is English it happened too )　
    Problem:
    On the Adobe Flash Player web page，the Right Click Menu that near the taskbar can not be pop up.
    And On the Flash Player Help home page(http://helpx.adobe.com/en/flash-player.html) has the same problem,
    and menu round the red circle on the below picture is the problem Right Click Menu.
    As this problem，If we program use the Flex，the problem that the Right Click Menu can not be pop up must occur.
    eg:
    IF there is many lines when we use the ListController ,the data nears the taskbar can not be used the Right Click Menu。
    Relation:
    The problem does not happen when the environment is below

    Question：
    Whether this problem is resolved? If yes，please tell me the solution，thank you!

  • RMI: Is it the right choice?

    I want to make an application that connects to 1 other peer. So I'd run the application and if I type in the IP of someone else running the same application, we can connect to each other and do stuff like chatting. Is RMI the right choice to make this happen?

    I would use Apache MINA library. Its easy to use, fast, more firewall friendly than RMI, more language-independent transmission format. http://mina.apache.org/
    Really. Where does it say that MINA knows a firewall from third base?
    Mina is a Java NIO library that just does TCP and UDP communications and intra-process pipes.
    It's not a competitor for RMI in any sense that I'm aware of.

  • The right choice

    hey, i have been reading around this site a. Is there no live chat at all for support or sales to discuss the best solution?? anyway.. i need some help making the right choice and setup with skype for my small business.
    There is two employees currently, we would like to have our own company number so we dont have to use our personal mobile numbers. if i am out of the office or just in general i can forward the calls to my mobile, or turn on the answering machine.I understand skype can do this.
    is my undertsanding correct for the following-->
    1--Me and my business partner both download skype for business.
    2--One of us downloads skype manager ( or is it a cloud thing?)
    3--Skype manager then adds both of our "skype for business" accounts to the skype manager
    4--Manager can then allocate funds
    5-- we both use skype for business as normal
    Q--how do i use skype business or skype manager, and have the premium membership etc., and what would this cost me per month ( australian)
    Q--how does a skype phone number work when you have two employees?
    Q--Are the skype numbers associated to the business account or the skype manager account
    Q--do i even need skype manager for just two employees when really only one person will
    make most of the calls.
    I may have this understanding wrong, and maybe someone can tell me a more effecient way for my small business to set up skype etc?
    thanks for the help

    Hi Martin
    With all you've said, the only advice I can give you is "go ahead"!
    You already know what to expect. Max out the RAM, and you should be set.

  • Is it the right choice to make ODI as ETL on OBIEE?

    Hi ,
    I have multiple source (file,xml,progress,express)
    And target is oracle (warehouse)
    Can ODI make the dimensional table from the multiple source?
    Can ODI do support the OLAP ? which way?
    Is it the right choice for DW with OBIEE?
    Sorry if this question will shown my foolish about BI.
    because I once use ODI on Data Integration part not BI part.
    Thank you

    Cristiano,
    My first suggestion is to rename your file. The "%20" in "cSegno%20flash%20page.html" indicates you actually saved it as "cSegno flash page.html." Spaces are not a good thing in file names. Better to use hypens or underscores when yon want to delineate word separation, like this (mixing the two conventions in one example): "cSegno-flash_page.html."
    I believe your site can be recreated using Dreamweaver to write the HTML and CSS, and can probably be affected using hot spots or jquery. Check out jquery solutions here. Whether you yourself can do the conversion will depend upon your coding skills. And people here will be happy to help.

  • Is MDB the right choice?

    We currently have a legacy order management application which is going to be replaced by a popular off-the-shelf OM product. The data modeling and concepts of the new OM application are different from the legacy application. Currently there are quite a few applications which directly connect to the legacy DB by JDBC etc for their data needs. In order to avoid impact on those applications it has been decided to keep the legacy DB as it is and feed the data from new Order Mangement application to the legacy application. We cannot use DB level replication due to some constraints. I am planning to create the new application, using MDB. It will subscribe to the messages generated by the business events happening in the new Order Management application, translate the data to legacy format and insert the data into legacy DB.
    Is MDB the right choice for this or do we have a more appropriate way of doing this?
    Also please let me know if there are any desing patterns which address this kind of a problem.

    Assuming your legacy apps don't need to update the new OM system an MDB sounds reasonable. You may want to consider passing the messages as XML and using a library (JAXB/P, castor etc) for parsing / inserting into a database.
    You should also work out how to handle technical failures updating the legacy database and poison messages (i.e. when an invalid message is received). You may decided to automatically retry technical failures a set number of times before moving them to a backout queue. There's no point retrying poison messages as they'll repeatedly fail, but you may need to fix / manually insert them.

  • Calling a Web Service in CRM . Is WEB UI the right place ?

    Dear Friends,
    We have some ECC Web Service to read some BP related data  available on ECC.
    I would like to red this ECC- BP Data in CRM using a readily available Web Service and then disply on WEB UI.
    I know how to create a web service in SAP CRM using the new WEB SERVICE tool as well as the old ways of creating a Web Service ( throgh WSADMIN which is obsolete now) . I also know how to cosume web service in a Word Template or Adobe form...
    What i dont know and would like to you experrts to help me know is
    How can i consume a web service in CRM and read the data on ECC for which this web service is exposed ?
    Is it possible to do it in WEB UI or there is any other way ?
    Any help in making me understand how to consume a web service in SAP CRM ( to read and use data in WEB UI and not word template or Adobe) is greatly appreciated.
    Looking forward for replies.

  • Is Web-Services the only way to trigger Workflow on Time-Based conditions?

    <p>
    Here is the requirement:
    When a Custom Object's record is set to a specific status and it hasn't been modified in 7 days an email should be sent to the owner to notify them to update the record.
    Any thoughts on how we can do this?
    Thanks,

    Tim, I would recommend that you post this question on the CRM On Demand Integration Development forum. Also, some of our On Demand partners are capable of creating this functionality with web services.

  • Document style Web Service the standard?

    Hi,
    A colleague of mine just told me that we should not be building RPC style web services since document style are the standard now. Is this true? I couldn't find any such phrase in WS-I BP 1.0.
    If this is not true then is it even a possiblity that in future Document style will be the standard?
    Thanks, Sid.

    In this context I think your friend is using 'standard' to mean 'reasonably common and quite trendy at the moment'.
    RPC based WS was a bad idea in because it destroys some of the loose coupling you gain using WS rather than say, CORBA, which is the number three reason for using WS. (number one being your boss spent lots of money on the tools and would look silly if you don't use them, and number two being WS tunnelling through firewalls).

  • BAM - Is it the right choice?

    I'm pretty new to BAM/BizTalk Server.
    After reading some articles regarding BAM, it seems that it is a tedious process to design a BAM solution.
    Our BAM needs are pretty basic, like displaying state of each of the workflow/message currently running in the BizTalk server. We do not require much-dimensional models and OLAP cubes. Just some basic way to query BizTalk data.
    Is BAM the right chocie for us? Any other option?
    Haider

    Hi Haider,
    First of all, it's not tedious process to design BAM Solution. I assume you want have visibility as to which workflow got failed, successful, the time it consumed and other business metrics etc.
    I would ask you to go through
    Business Activity Monitoring Tutorial it will surely make things look easier and less tedious.
    You can also have look at following article for more insights :
    http://social.technet.microsoft.com/wiki/contents/articles/5599.business-activity-monitoring-bam-survival-guide.aspx
    But if it's about only message status, service status or application status then you can utilize
    Administration console
    and
    Group hub page (for basic queries).
    Tracking is required in either case,

  • SAP ABAP -- Is it the right choice for entering into SAP Technology

    Hi
    I have 4 years experience in JAVA/J2EE. But I am planning to switch my career now to SAP. I am planning for doing course in SAP ABAP.
    Please anyone suggest me if SAP ABAP would be a right choice. And how is the demand in SAP ABAP at present.
    Can I explore myself in SAP ABAP at this point.
    Best Regards
    Ranjan

    Just out of curiosity - why switch to SAP in the first place?
    Yes, if you are good at programming, then yes ABAP is the way to go. But please remember that while searching for jobs you will still be considered a fresher - in ABAP. You JAVA background has very little - if not zero - significance when it comes to experience.
    Of course you can go ahead and explore the ABAP world. You can download the trial version from the site and start pulling a few levers to see if you are comfortable.
