Connecting ORACLE 10G, SAP R/3 to Xcelsius dashboard

Dear All,
I have a scenario with a customer, where in we have to develop an XCelsius dashboard over Oracle 10g source. Customer is keen on building dashboards directly on top of Oracle 10G (or) SAP R/3.
Could you please let me know - which approach is good for Performance of Dash boards?
1)ORACLE 10G>NON SAP Universe>WEBI Report>Live Office> XCelsius
2)Oracle 10GSAP R/3 (Using of Data Services)>ABAP Function Module>Crystal Reports2008>Live Office> XCelsius.
3)Oracle 10G>Crystal Reports2008>Live Office-->XCelsius
Thanks and regards,
Raghu

HI Raghu,
1)ORACLE 10G>NON SAP Universe>WEBI Report>Live Office> XCelsius
Here we can make use of the background scheduling of webi reports and use latest instance if the volume of data is more in the tables.
As webi is a very good tool we can consolidate data and optimise the performence of the dashboard..
Note: Universe designing should be done very carefully.
2))Oracle 10g/SAP R/3 (Using of Data Services)>ABAP Function Module/Infoset>Crystal Reports2008>Live Office> XCelsius.
SAP R/3>function module/Infoset>Crystal repotrs 2008->liveoffice>dashboard.
Here we can make use of the background scheduling of Crystal reports and use latest instance if the volume of data is more in the tables.
it is good if you implement all the logic in ABAP side and simplify the  work at Crystal report side so that the dashboard performence is good if the refresh option is ONDEMAND.
Note: ABAP consultant is needed.
3)Oracle 10G>Crystal Reports2008>Live Office-->XCelsius
In this case you have to implement all you logic in Crystal reports and schedule the data and use latest instance for better performence of the dashboard.
Decision has to be made depending on the volume of data logic behind report to display the final data..
if you are using webi in ur flow you can have better staging and adhoc analysis can be given to the user .
Case 2 is also good if ur making every thing at ABAP level .
i dnt suggest 3rd case.
Hope this helps you ..

  • Error to connect oracle 10g client and designer BO 4.0

    hello,
    I try to connect oracle 10g client and designer BO 4.0.
    I created an ODBC connection to function in the administration tools of data sources but I can not connect once in designer.
    I tried using the driver directly oracle designer 10 but I have the same error that is this:
    DBD: ORA-12154: TNS: connection identifier specified could not be resolved
    someone there had the same concerns?
    cordially

    Hi,
    so it looks like that your TNSNAMES.ORA file isn`t properly configured. Thats why you can connect with the IDT to your Oracle Database.
    Your DBA`s should sent you the correct TNSNAMES.ORA file or the entry for your DB prior. After the tnsping works, you will be able to use the IDT properly.
    Regards
    -Seb.

  • Connecting oracle 10g express edition to jdeveloper

    I am having all kinds of problems connecting oracle 10g express edition with my jdeveloper 10.1.3.3. I can query the database from my command line so I know it is set up, but for whatever reason jdeveloper will not connect with it. When I try to connect with the database through jdeveloper here is the error I keep getting:
    Listener refused the connection with the following error:
    ORA-12518, TNS:listener could not hand off client connection
    The Connection descriptor used by the client was:
    localhost:1521:ORCL
    I have been all through the google results looking for an answer and have come to the conclusion that it is something with either the listerner file or the tns file, but as of yet have been unable to locate them. here are both of those files too.

    Please any help would be appreciated I have been at this for days, thanks.

    This has to be some kind of bug with 10g express because I see lots of people having similar problems. I'm in the process of uninstalling 10g, and I will re-install it see if that makes a difference. Again if anyone has any other ideas please keep them coming because this is utter BS it shouldn't be this hard.

  • How to connect Oracle 10g from OBIEE on Linux?

    - OBIEE 10.1.3.4.0 is running on Cent 5 Linux M1 (*64* bit). My Oracle database is running another similar machine M2.
    - I installed oracle 64 bit client on M1 but could not connect to run the report, connection issue. Even nqcmd didn't helped.
    - I guess it was because OBIEE is *32* bit application and hence need 32 bit client.
    - I tried installing Oracle 32 bit Linux client on M1 but installation fails with some dependency (Not sure if we can install 32 bit client on 64 bit machine)
    Q1 - Any suggestion at this point?
    Q2 - Is there any way we could connect OBIEE to Oracle via ODBC drivers. I could not found any odbc driver/so file when I wan installed 64 bit client. Any suggestion for this?
    Thanks in Advance!

    Hi All,
    The soultion of this is,
    When we are establishing a connection with the Oracle database we need to take care of 4 things,
    1. JDBC driver
    2. Server URL
    3. User name and password
    4. Validation Query,
    In my case the validation query was specific to SQL that is select getdate(). its should be replaced with select sysdate from dual.
    than the above error il not happen.

  • Connecting SAP R/3 to Xcelsius dashboard

    Hi all,
         I've a requirement where I have some reports in SAP R/3 and based on those reports I need to build a single Xcelsius dashboard.  What I know is I have to use Crystal Reports which fetches the data from R/3 tables and in turn use these Crystal reports as data source to my Xcelsius Dashboard and I want this dashboard to be a live one.
    But how should I connect to the Crystal reports data directly from Xcelsius ??
    Is it through Live Office, if yes can someone describe the process to do it as I'm unaware of it ??
    Thanks
    John

    Hi Anil,
                   The reports in SAP are standard reports where each report is having 4000-5000 lines of code, and to replicate
                   the same logic in Crystal Reports to build reports which in turn can be used a data soure to Xcelsius dashboard is a
                   huge task and time consuming as far as I know from outside of it.......
                   Is there any other approach to achieve this ?
    Thanks

  • Can not connect Oracle 10g express edition from report builder.

    I have newly installed report builder . Different home was selected for Report builder and oracle. Oracle database server is also in the same machine. But i am not able to connect my oracle 10g express edition database. It throws error ORA-12154 : TNS could not resolve service name.( same error displayed while trying to connect from SQL Plus).But from toad i am able to access the database. May be because here I am able to select the proper home.
    Here i am adding my tns entry
    XE =
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 1ECA66A679AB494)(PORT = 1521))
    (CONNECT_DATA =
    (SERVER = DEDICATED)
    (SERVICE_NAME = XE)
    can any one suggest what the actual problem is?
    Thanks ..........

    Hello,
    Oracle 10g XE is rather specific and, I'm not sure that you can upgrade it to 10.2.0.4 .
    However, Oracle published an Upgrade Guide for Oracle Express Edition but, it's limited to *10.2.0.3*:
    http://download.oracle.com/docs/cd/B25329_01/doc/server.102/b32391/toc.htm
    But be careful:
    Once you have upgraded to Oracle Database 10g, you cannot downgrade back to Oracle Database Express Edition.Hope this help.
    Best regards,

    Look at what I have in my Sqlnet.Ora file,
    # This file is actually generated by netca. But if customers choose to
    # install "Software Only", this file wont exist and without the native
    # authentication, they will not be able to connect to the database on NT.
    SQLNET.AUTHENTICATION_SERVICES = (NTS)
    Please kindly help me out of this as it is very urgent. I can connect from browser using http://127.0.0.1:8080/apex but cannot connect from my C# code and Server Explorer. What is likely to cause this error.
    Thank you for helping me in advance.
