XApps Analytics 1.1 Ramp Up Question about Systems

Hi,
have installed xApps Analytics 1.1 Ramp Up version of VC ok and got some basic models working against the standard SAP_BW system which was already configured with NW2004s for single sign on with BW.
I have added two new systems in the portal (one JDBC and one SAP R/3) under Systems in System Configuration. These test fine from within the portal.
However, within VC when I got to Find Data I still only have one system (SAP_BW) in the drop down.
Any ideas? Have stopped and started with no effect.
Many thanks,
AB

Yep. Tried everything within my repertoire now!
I further thing - I have setup user mapping user admin,user via user j2ee_admin.
I am logging on as a VC user with the VC Role.
Could this be anything to do with it?
Regards,
AB

  • Problem\question about System.in and DataInputStream

    Hello everybody,
    I have the following code, trying to read an int and a string into two variables using System.in and DataInputStream:
    package objectIO;
    import java.io.*;
    public class WriteStudentObject
         * @exception IOException Can not read the file
          public static void main(String[] args)  throws IOException
              a loop could be used here to create more than one
              student object and write each one to a file
              Student mary = new Student("Mary Martin", 12345);
              // open inputstream to read data from keyboard
              InputStream is = System.in;
              DataInputStream dis = new DataInputStream(is);
              int  g;
              String c;
              for (int i =0; i < mary.grades.length ; i++)
                  System.out.println("Enter a grade for test" + i);
                  g  = dis.readInt(); //*QUESTION 1*
                  System.out.println("Enter a comment for test"+i);
                  Datainput stream can read String
                 and store as text or reverse
                  c = dis.readUTF(); //*QUESTION 2*
                  mary.grades= new Grade(g,c);
    try
    FileOutputStream fos = new FileOutputStream("c:\\personal\\test\\studentObject.dat");
    ObjectOutputStream oos = new ObjectOutputStream(fos);
    oos.writeObject(mary); // write obj to file
    oos.close();
    } catch(IOException e) {
    System.out.print("Error: " + e);
    System.exit(1);
    The class uses a Student object -attributes are name\String, id\int and Grades (Grade class has grade obtained\int and a comment from the teacher\String).
    My questions are: (as bolded in the code)
    1) at "g  = dis.readInt()" I have to press Enter 3 times to finish the reading (one after entering a single int and then just 2 times Enter). Should I add bellow this line "System.in.read()" to clear the newline\return character?! What exactly does "System.in.read()" clears? After leaving the method readInt() the variable g has an enormous value... like 9 digits... why? I also tried "g  = (int)dis.readInt()" but the results are the same... I want to read an int from keyboard, but using DataInputStream, not with System.in.read()
    2) at this line the program never ends, it tries continuously to read characters... no matter what I enter it does not complete... I want to read a String from keyboard, but again using DataInputStream...
    Many thanks in advance (and hopefully now I can assign the offered stars...)

    I read an int form keyboard with 'int read_int = System.in.read();' but why I must, after this line, enter a new System.in.read()? (what does this clears? the return character? )Yep. Note that InputStream.read() only reads the next byte of data. If your user had input something that required multiple bytes to represent, you would not have read all of it.
    Fun Fact: Even if you had used Scanner.nextInt() to get your integer from the console, you still need to do a .nextLine() as .nextInt() only reads up to the newline and does not consume it.

  • Question about System.in, FileoutputStream and blocking

    Hello everybody,
    I have written a simple java program that read the System.in and append it to file (which is the first argument of the program).
    Here is the context: my client launch several instance of this program at the same time, with the same file passed in argument. In a first time, I did not use the FileChannel.lock() method because I didn't know there will be several instance, but this is not the question.
    The problem is simple: sometime, I can't figure why (and this is why I'm here to ask you), one of the process block, and stay like this until my client kill it.
    So why? It has something to do with the absence of FileChannel.lock()?
    My client is on Solaris, don't know which version, with a JDK 1.5.0_04
    Here is the code:
    InputStream is = System.in;
    InputStreamReader ir = new InputStreamReader(is, encodingMode);
    BufferedReader reader = new BufferedReader(ir);
    FileOutputStream fos = new FileOutputStream(args[0], true);
    String lineSeparator = System.getProperty("line.separator");
    String buf = null;
    while ((buf = reader.readLine()) != null) {
         fos.write(buf.concat(lineSeparator).getBytes(encodingMode));
    }I think the FileChannel.lock on the output file will solve the problem, but I'm just curious about that odd issue.
    Thanks for help, and excuse me for my bad english.

    Ok, I try to launch 20 occurences at the same time on opensolaris 2009.06 and here is what I've got:

  • Urgent Question about System Center Server Names and Dashes

    Hey guys I have a quick Urgent question that would be awesome if it happens to get answered quickly :). 
    So in the past we had problems with different server names in components of System Center when setting up different servers.... I never myself saw the errors or what it did, but an absentee colleague did. For example is anything wrong with a name setup like
    xx-scom-01 / xx-scom-02  as compared to the standard scom01 scom02? We have a certain naming convention we are moving to and I wanted to see if this was fixed. I wanted to say it had something to do with the hyphens... anyways any foresight anyone can
    provide would be awesome. Thanks!

    Dashes in the name will work fine.

  • Various questions about System Restore Point

    How can I delete old System Restore Points?
    Is it possible to move the folder that holds them to a different drive then C:?
    Can I limit the amount of data System Restore is allowed to have?
    I have downloaded the TreeSize program to see what is using up so much space on my SSD and a folder named "System Volume Information" has 17GB of storage. Now I have found out that this is the folder that keeps System Restore Points and I checked
    on my restore points. There are too many of them and I was wondering if I could delete some of the old ones? I read on another post that someone said that you could limit the amount of data System Restore is allowed to use. Is this possible?
    Best Regards.

    Hello HurricaneHojax,
    Here I list the requirement, and please correct me if I have misunderstanding:
    1. Delete some System restore point
    2. Move the folder that hold system restore data to a different drive then C:.
    3. Limit the amount of system restore data.
    1, We can delete some system restore point.
    For more information, please take a look at the following article.
    http://windows.microsoft.com/en-hk/windows/delete-restore-point#1TC=windows-7
    2,We are not able to move the system restore folder to other Drive.
    3, We can limit the amount of system restore data.
    For more information, please take a look at the following article about managing the disk space that is used by System Restore.

  • Question about System Properties?

    Can anyone shed some light apon this, if i have my midlet running in the background
    i.e. display set to null.... can j2me read the state of the phone system?
    Can j2me read any 'system property' like active/idle/keylocked??
    ..../fg

    Well generically the answer is NO.
    There is always a chance that some device manufacturer have supplied (if at all) some API to do this. But I am yet to heard about any device in the market to have this. Only what I heard that Nokia is in its way to supply some API like this with there Series 40 3'rd edition phones (ref. http://developers.sun.com/learning/javaoneonline/sessions/2006/TS-4447/index.html?). But they haven't yet announced anything on the release of it.

  • Question about system requirements with upgrade

    I want to upgrade to Leopard which has iLife '08 but as I was reading about iMovie '08, it says that the minimum processor spec is a g5. You can see in my signature, my Powerbook is a g4, will iMovie not run at all (or very well even) or will the installer give me an option not to install the entire iLife'08 suite over what I have right now? Thanks!

    As the Prime Minister has pointed out Leopard doesn't include iLife 08. It is a separate $79 purchase.
    Your G4 (and mine) can't even install iMovie 7 so a purchase would do you no good.
    But, if you bought a new Mac it would come installed with Leopard ($129) and a free version of iLife 08.
    Over $200 in savings right off the bat!

  • Questions about System Requirements for Adobe Air programs

         Earlier today I asked someone who runs Tweetdeck if they knew what the system requirements were for running Tweetdeck on my desktop (Windows)
    they gave me a link here: http://www.adobe.com/products/air/systemreqs/
    and I found this:
    Windows
    2.33GHz Intel® Pentium® 4, AMD Athlon® 64 2800+, or faster processor
    Microsoft® Windows® XP Home, Professional, or Tablet PC Edition with  Service Pack 3; Windows Server® 2003 or 2008; Windows Vista® Home  Premium, Business, Ultimate, or Enterprise (including 64-bit editions)  with Service Pack 2; or Windows 7
    512MB of RAM (1GB recommended)
    Here are my computer statistics:
    Operating System: Windows Vista™ Home Basic (6.0, Build 6001) Service Pack 1 (6001.vistasp1_ldr.101014-0432)
               Language: English (Regional Setting: English)

    Will me only having a 2.1GHz processor really affect how my performance is with Adobe Air products/apps in general?

    Yes- I've had some lower price pc's using an Adobe AIR app and can tell the difference.
    Computers where performance was a huge issue was Compaq CQ56 & Toshiba Satellite C655D
    These computers are under 2.0 GHz and the app seems to freeze up on occassion or run slower.

  • Question about system catalog tables in oracle 11g database

    We have a customer issue and in order to trobleshoot that we need following information. We would really appreciate any input. I opened SR with support and they asked me to open a discussion here. Please see following.
    what is the meaning of the part# column of the sys.tabpart table and what are the possible values that can be entered into this system catalog table. Our findings are that Oracle may have varied the meaning of this column as the data that we are seeing returned is now > 2gig which does not make sense for a partition number.
    Our stored procedures use this information to retrieve information from the Oracle system tables to process a partitioned Oracle table. Our research has found that the limited description for this table (and columns) can be found in the following Oracle member at the following location:
    dpart.bsq --> ...... oracle database path... \RDMS\ADMIN folder
    The comment within this file notes the following:
    " this value is "partition number (see discussion below)"
    However, there is no additional discussion to describe what the value means and the possible variations. We need this information to move forward with our problem diagnosis and
    to see what kind of updates we need to make for our stored procedures....
    Thanks a lot in advance.

  • Questions about system connections

    Would someone help me clarify something?
    When the ECC QAS system has been copied from the PRD system, the connection between the ECC QAS and the BID system is broken. I was told by Basis that after the copy, the connection has to be restored, and for some reason restoring the connection between the QAS and the BID system, the InfoSources and their transfer rules are completely wipe out from the system.
    We are using the business contents and have not yet did the migration.
    I am not sure why restoring the connection between the ECC and BID system would cause the InfoSources to de deleted. Has anyone come across this problem? Is it something that Basis can prevent from happening? I have not seen this from BW 3.5.

    Hi,
    We tried your suggestions but it is still wiping out the InfoSources. We are aware that the broken connection between the ECC and the BI systems will allways occur when we do a copy. Restoing the connection between the ECC and BI systems is causing the wipe out of the InfoSources.
    We're asking if anyone has come across this problem and was able to fix it,

  • Questions about system requirements w/FCE4  (AVCHD/Intel)

    As you can see I have a Power PC Dual G5. I also have a JVC GZ-HD7 HD Everio camcorder. Im pretty dumb when it comes to this AVCHD. Can anyone tell me if this is the format my camcorder uses all the time or just when using the SD storage? Secondly, in regards to Final Cut Express 4 the Mac web site said:" For AVCHD: A Mac computer with an Intel processor" Is this true or just a marketing thing? I want to be able to edit HD clips that I capture with the JVC. I haven't bought the FCE4 yet. I hope someone would be kind enough to tell me what the best setup would be, (out side of buying a new Mac Pro). Prospectively, thank you!
    Benjamin

    Thanx Tom. Now that I know that my JVC does NOT shoot in the AVCHD & I don't currently have a Mac with an Intel, would you be so kind to suggest the best editing software for me to use with the current equipment I have. (Keep in mind I usually shoot in full HD) Maybe a previous version of Final Cut Express? I have been editing through my Power Book G4 with iMovie HD 6 but I would like to use my Power Mac, which has the new iMovie 7.1 ( I havent really used this yet because it didnt seem to have the effects options iMovie HD 6 has) Should I down load HD 6 to my G5 or is there a more highly recommended application? Pospectively thank you, Benjamin

  • Questions about system temps (way high, urgent)

    I've just got my 865PE Neo2-FISER and was playing around with some settings.  I ran the CoreCenter just to try it out and it says my NorthBridge is running at 63c???
    Is this just a invalid sensor, or is this really the case?  If it is, I'm going to go right in and see if the heatsink is even touching it.  Temps are as below:
    CPU: 43c
    CASE: 30c
    NB: 64c
    All temps are at full load.
    Thanks ahead of time guys.  

    NB doesn't have thermal sensor. That value is fake. Get the latest CoreCenter. ok?

  • Question about System.in.read()

    Hello Everyone,
    I am having a problem with System.in.read(). I want it to produce an int value, however when I use it the value always comes out to 49.
    class Lawn2
         public static void main(String []args) throws Exception
              int lawnSize, lawnPrice, weeklyAmt, length, width;
              length = 50;
              width = 10;
              System.out.println("Enter Width");
              width = System.in.read();
              System.in.read();
              System.in.read();
              System.out.println("You entered " + width);
              lawnSize = length * width;
    }

    Obvious as System.in.read() reads a byte and converts to ASCII equivalent when assigning to Integer.
    Here is a sample code that shows one of many ways of reading input console data
    import java.io.*;
    class Lawn2{     
         public static void main(String []args) throws Exception     {          
              int lawnSize, lawnPrice, weeklyAmt, length, width;          
              length = 50;          
              width = 10;          
              System.out.print("Enter Width : ");     
              BufferedReader ln = new BufferedReader (new InputStreamReader(System.in));
              width = Integer.parseInt(ln.readLine());
              System.out.println("You entered " + width);          
              lawnSize = length * width;
    }
