EAR and EPA to SDA

Hi all,
We have to create an EP Business package with web dynpro applications. How can we package the portal contents and web dynpro applications into a single sca/sda package?
As far as I know, the web dynpro EAR files can be converted into SDA files during the assembly process in CMS. The EPA files can be converted to SDA using command line tools of MAKe utilities. Thus there will be two SDA files. Then these SDA files has to be combined into an SCA archive.
Is this the right way do this? Can anyone help me with a better option if any?
Thanks and regards,
Shyam.

Hi,
There is no need to convert the .ear files into .sca or .sda as .ear file can also be deployed directly.
Also regarding the Package, you need to just export the package as a .epa file.
This would work.

Akshay

  • Creation of SCA Package from EAR and SDA

    Hi All,
    As we know that when a CAF project is created then another 4 projects( dictionary, ejbmodule, permission and webdynpro) are created with the main CAF project and at deployment time five files are deployed at J2EE engine. Among them four are EAR files and one SDA file(for dictionary project).
    I want to put all the five files ( four EAR and one SDA) within a SCA package. So, how can I do it? I have got a help(Note number 696084) of creation SCA from SDA and EAR but that is applied for NetWeaver'04. Now I am using NetWeaver'04S and NWDS SP7 and SP8. So please could anybody help me to solve the problem.
    Thanks and Regards

  • How to covert EPA to SDA file

    Dear all,
    Can any one help me how to conevert EPA file to SDA.
    Thanks and Regards
    Suresh Kumar

    Hi,
    Check this SAP note out 696084, this contains the links for downloading the sapmake_util.exe , this tool you will be needed in order to convert EPA to SDA, once you download this tool, unzip this into your SAP folder in program files. the blog provided by Harini is very nice one.
    Please not the syntax of converting is
    on cmd you need to type this
    epa2sda <filename.EPA> <SDA filename youwant.SDA>
    dont forget to give .EPA and .SDA as i have shown, else you will get errors.
    Hope this helps,
    Regards,

  • EPA to SDA conversion !!

    Hi all,
    My scenario is :
    1) i have created a transport package from portal to create EPA file,
    2) I am using <b>sapmake_util</b> tool to convert EPA to SDA,
    3)i have downloaded this tool from SAP NOTE 696084
    4)All environment variables are set.
    now when i run this tool i am getting error that
    BUILD FAILED, ERROR WHILE EXPANDING <EPA FILE>.
    What could cause this error, this doesnt generates a log file so i could not find any cause..
    Has anybody faced this issue?? how to get rid of this??
    Any help will be highly appreciated.
    Thanks in advance,
    Regards,
    Ameya

    I resolved this of my own...
    in cmd i was typing<b> epa2sda FILE.EPA  FILENEW</b> = this is wrong, where as correct way is <b>epa2sda FILE.EPA  FILENEW.sda</b>
    i was also getting error while creation of sca, for this you need to create a folder in sapmake_util folder say MyCollection, now put sda file that you created just now, and now on cmd type
    sca MyCollection MyCollectionNew
    this will create your business package and an SCA file...
    Hope this info will help to others as well..
    Cheers..

  • IPhone 4 vibrates in my ear and makes audible sound while on call

    Ever since I did the 4.2 update if I am on a call and message comes in, the phone vibrates in my ear and plays an audible sound that everyone around me can hear and also my caller. First time it happened it scared me so much I about dropped the phone. Now it just makes me mad. When the 4.3 update was released, I was hopeful this "bug" would be fixed. No such luck! Has anyone experienced this? Is there some way to stop the phone from doing this and have it just do the "soft" tone that only I can hear? I went to the apple store and the guy I spoke with suggested just turning off the vibrate. That is not the solution. What about the sound that it plays? Am I supposed to turn that off too? Then it wouldn't make any sound or vibrate. Niiiiiice! Just what I need. A phone that doesn't ring or vibrate.
    Someone HELP!
    Thanks!

    I started a thread like this with my 3Gs iPhone. My solution was to disable the "Vibrate" feature under "Settings, Sounds, Silent" and when I get a phone call I just use the "silent/vibrate" switch on the side of the phone and it turns off all the sounds. Just make sure that you have the "Vibrate" under "Silent" turned off. That fix works for my iPhone 4 as well. Hope this helps.
    Here's my thread from a while back: "http://discussions.apple.com/thread.jspa?threadID=2314868&tstart=0"

  • How to handlle multiple ear and common database.

    Hi Friends,
    Need urgent help.
    I working on a project where there will be multiple ear ,each for one application.
    There are 4 project and 4 ears and one common util war file which will be shared by all ears.
    Problem is : 3 of the projects will use same database tables. I am using hibernate ORM mapping for database table.
    Q1. In the above scenario db access table are 90% common in 3 projects. Should I go for instead of 3 ears club into 1 EAR and current 3 project as a 3 module in 1 club ear or per project one ear?
    Pls suggest me the approach and advantage and disadvantages of the approach.
    Q2 : Should I put the data-beans and table mapping files (e.g account.hbn.xml) & hibenate.cfg.xml file in common war(centralized or shared) or replicate the copies of all beans mapping xml and beans classes in every ear.
    If you suggesting to use the centralized/shared data configuration approach then how EAR 's jvms will handle Transaction for every ear.
    I am using Websphere app server6.1, hibernate3 and db2 8.0
    Waiting for your interesting replies.
    Thanking you in advance.
    Navin.

    How are you going to handle upgrades if a database change is needed?
    If it is per application then you need to keep the code by app. If across applications then you need to keep the code separate.

  • EAR and WAR

    Hi,
    i need to know about .ear and .war,what exactly do in atg. why we use.
    thanks.

    They are the standard file formats for storing and distributing JEE applications. A War file groups JSPs, servlets and all related files to create web applications, and a Ear file groups all the various War and Jar files required to create an 'enterprise' application.
    Hope this helps.

  • Vdbench 504, SNIA, and EPA

    If you are NOT downloading Vdbench as part of the SNIA and EPA power measurement effort, I HIGHLY suggest you download version 503 instead, unless you have some spare time to help me make sure that everything NOT EPA/SNIA related is still working fine. In that case, if you find a problem with 504, rerun the same test with 503 to make sure it is indeed a 504 problem.
    Henk.
    In collaboration between the Oracle, SNIA and EPA, new functionality has been added to Vdbench to support the SNIA Emerald Power Efficiency Measurement Specification.
    The Vdbench 504 executables can be found at Vdbench Downloads
    SNIA information can be found at http://snia.org/forums/green.
    At some time in the near future the source code of Vdbench504 will also be placed on OTN, I will update this post as soon as that task has been completed.
    The current plan is to use this OTN forum as a support vehicle for Vdbench, including any Vdbench related questions or support issues. Non-Vdbench related questions around the SNIA workload should be addressed to (still looking)
    Once I figure out how to do it I'll assign Steven Johnson as a co-moderator for this Vdbench forum, Steve has been the main contact person with the SNIA, while I (Henk) has done the coding and testing, though Steve did come up with the wonderful new 'Hot Band' algorithm.
    We will do our best to monitor this forum, though please understand that our workload and priorities may not allow us to respond to you immediately.
    The main emphases of Vdbench 504 has been the inclusion of the new SNIA functionality. In theory all old existing Vdbench functionality should just continue to work, but, as I have learned after 42 years in this business, 'should' does not always mean 'will'. Please let us know if you find anything questionable.

  • Deploying EAR and EJB (ClassLoader Question)

    Hi,
    Have a few queries. Appreciate any quick answers.
    (a) To deploy a EAR or EJB jar to WebLogic server, is it necessary to include the jar location specifically in $CLASSPATH?
    I think not. Am I correct?
    (b) Is the bean/EAR deployed at module level? Is there a setting for this - is it at bean deployment descriptor? Where can I find this?
    If (say) I need to update an EJB, do I un-deploy, update and re-deploy it?
    Or must I restart the entire WLS container?

    --> An EAR includes one or more EJB files. You don't need to specify the location because it's contained at application.xml file inside the EAR.
    --> Each bean has a deployment descriptor. You can see it at META-INF directory
    If you need to update an EJB (that it is not part of and EAR), you are right.
    The WLS container not need to be restarted.
