Need help - DATABASE INDEPENDANCE

Hell all,
Can you please help me to answer this question?
"What techniques can be utilised to guarantee database independence?"
Really looking for the answer from you.
Thanks in advance.
Himanshu

"What techniques can be utilised to guarantee
database independence?"Database agnostic approach? That depends which products you have to support with your solution. For example: mysql 4.x did not provide mechanisms such as views. Very view databases support things like autonomous transactions or materialized views, just to name some oracle features. So if your solution should work on the given databases, you would have to make sure that you don't use materialized views, autonomous transactions or views in your solution.
You could however provide workarounds for missing features in the mentioned product(s), depending on the given requirements and budget. And have a look at different locking models, etc. There are frameworks like hibernate, that solve some issues, but not all of them.

  • Need help Crystal Reports running in BO 4.1 while using Universe as database connection.

    Sorry, I may not know how to describe this in the correct technical manner, but I'll explain in as simple terms as I can.
    I open up Crystal Reports 2013 click new document
    and it begins to ask for Database Expert.
    I select Universes and log in to my Business Objects Enterprise Explorer.   I then select the Universe that I want to write my report with,
    then i save the rpt on my local machine.
    then I log into my Business Objects 4.1 CMC or BI and upload this rpt file so that I can begin to schedule the report for example...
    but the problem i have is whenever I try to run the report, 
    it asks for a prompt for my database connection...  
    it displays the Universe name, but User Name Password, I am not sure what to write,
    do I write My login for Business Objects?  do I write the user name password of the database that Universe uses?
    in CMC I see a database configuration,  I tried many combinations and still have been receiving the following error message
    The viewer could not process an event. The database logon information for this report is either incomplete or incorrect. []
    ---- Error code:0 [CRWEB00000119]
    From all I read the point of using the Universe in Crystal reports is to be automatic in such a way that it doesnt need the database conneciton, because its technically using the Universe as the database connection....
    so what am I doing wrong here?    maybe its my database configuration,    I keep reading that it doesnt need anything...   that you upload the Crystal Reports and it would just work...
    any help with this issue would be greatly appreciated..
    thanks
    -Daniel

    Hi Daniel,
    What is the reporting DB used?
    The trick with your configuration is the following:
    - Universe Designer: 32bits application that may work fine on your desktop
    - Crystal 2013: 32bits application as well
    - When you export to the repository, Web Intelligence (64bits) has to process the Universe to extract the query.
    Your server should have the drivers required for Crystal + Universe: 32bit and 64bit versions.
    See more details on this KBA:

  • Need Help/Advice with Photo Web Gallery coming from SQL Database

    This is my first attempt at a database driven website. I assume what I am trying to accomplish should be fairly easy for more experienced but I am stuck at this point.
    First, let me explain what I am trying to accomplish.
    I want to create a thumbnail photo gallery displayed in columns and rows. I want to be able to hover over or click on the thumbnail image and have a lightbox script display the image over the thumb page. I am developing locally right now with intent to upload to the hosting site upon completion.
    I am developing with ASP vbScript pages. I have an SQL database where the paths to the image thumbnails and pictures are stored in a table. On the gallery page, I have created a div tag to hold my image recordset. Within this div, I have inserted 3 absolute positioned divs to hold the pictureID, the pictureName and the image inserted as a datasource. I then inserted the information from the bindings panel of my recordset. Last, I used a horizontal looper extension from Tom Muck to get the thumbnails to display in columns and rows. Everything works up to this point just fine.
    Now, I want to be able to hover or click on a thumnail image and have it displayed in a lightbox. I downloaded and used a javascript called Lightbox 2 which contains 3 javascript files and a css stylesheet. I inserted the files into the head tag like instructed to but could not get things to work properly. Here is where I need help. Currently, I am clicking on the thumbImage binding within the image Div and creating a link holder. I am then binding the larger pictureImage to it with the a.href selected in the bind to. I am then adding the command to call the lightbox javascript. Now, when I test my page, my thumbnail images do not show up (my alt text does in its place) but the links are in place and you can click on the alt text and it will return the correct larger image, but not in the lightbox, just in a new window with no styles.
    Am I going about this correctly? Can you use lightbox scripts with data-driven galleries? Does anybody have any suggestions of what I may be doing wrong or missing? Are there better ways to go about accomplishing this?
    Any help would be appreciated as this dynamic data thing has my head spinning. Although I know a database is needed to simplify the update and maintenance of the photos while allowing them to be searchable by keywords and tags also set up in the database.
    Thanks

    As I explained, I am developing locally a the moment. I will see about getting the databased moved up to the hosting server and then provide a link for an example.
    In the mean time, can you or anyone else explain a way that you would go about displaying an image thumbnail photo gallery laid out in rows / columns, with any lighbox script that would overlay the larger image over the existing page instead of opening a new browser window?
    I don't have to use the method I tried to describe.
    In all of the lightbox examples I have looked at thus far, they give instructions on how to append that javascript to a single static image or a group of static images, not images from a datasource. That is where I am getting confused.
    Don't know if this will help or not but please see code below:
    Javascript and CSS positioned in head tag
    <!--beginning of lightbox script with css -->
    <link href="CSS/lightbox.css" rel="stylesheet" type="text/css" />
    <script src="Scripts/protype.js" type="text/javascript"></script>

  • Need help toUpdate or insert in to AS400 database

    Hi all,
    I have created one scenario in which I am using JDBC receiver adapter,
    now the database at the end which is to be updated is the AS400 database
    which has the concept of liabraries and staging tables.
    while mapping the Inbound message type I use the structure as
    <MT>
      <Statement>
           <Tablename>
                  action
                <access>
                      <field1>
                      <field2>
                <key>
    I assign a const. 'update_insert' to action attrib. but when I activate the adapter at the end the error I get is :
    'field1' column does not exists in 'Tablename'
    But when I use a JAVA code for doing the same the data is successfully updated on the database.
    I tried the same thing using MS Access database it works fine but not AS400
    need help.
    Thanks
    Ranjit

    Ranjith,
    The process is the very same for  AS400 too. We are doing operations with AS400 and we dint face any problems. Hope you have already deployed the JDBC drivers in your XI server.
    Change your Data type slightly.
    <MT>
    <Statement>
    <table action = UPDATE_INSERT>
    <table>specify the table name in library.table  name eg: LIBRARY.TABLE1</table>
    <access>
    <field1>a</field1>
    <field2>2</field2>
    <access>
    <key>
    <field1>a</field1>
    </key>
    </Statement>
    </MT>

  • Need help for importing oracle 10G dump into 9i database

    hi, Someone help me to import oracle 10G dump into 9i database. I'm studying oracle . Im using oracle 10G developer suite(downloaded from oracle) and oracle 9i database. I saw some threads tat we can't import the higher version dumps into lower version database. But i'm badly need help for importing the dump...
    or
    someone please tell me the site to download oracle 9i Developer suite as i can't find it in oracle site...

    I didnt testet it to import a dump out of a 10g instance into a 9i instance if this export has been done using a 10g environment.
    But it is possible to perform an export with a 9i environment against a 10g instance.
    I am just testing this with a 9.2.0.8 environment against a 10.2.0.4.0 instance and is working so far.
    The system raises an EXP-00008 / ORA-37002 error after exporting the data segments (exporting post-schema procedural objects and actions).
    I am not sure if it is possible to perform an import to a 9i instance with this dump but maybe worth to give it a try.
    It should potentially be possible to export at least 9i compatible objects/segments with this approach.
    However, I have my doubts if this stunt is supported by oracle ...

  • Need help connecting to Oracle to create database

    Am student taking DBA course; have altered pfile so that path shows where createdb is located. Cannot connect to Oracle; keep getting message "insufficient privileges." Createdb file amended per book to "REMOTE_LOGIN_PASWORDFILE=exclusive" and still can't connect. Can I grant connect privileges to internal/oracle? Tried several times to create database and am now using new database name to try again, but when I get to svrmgrl and type in "connect internal" and give password "oracle" as book says to do I get the "insufficient privileges" message again. Need help.

    Linda,
    when you use exclusive in remote_login_passwordfile is necessary make one file. Use the following instructions:
    orapw file=orapw<SID> password=<password> entries=<users>
    where
    file=name of password file (mandatory)
    password=password for SYS and INTERNAL (mandatory)
    entries=maximum number of distinct DBA and OPERs (opt)
    There are no spaces around the equal to (=) character.
    Find orapwd.exe by Windows Explorer

  • Need help using dbms_scheduler to submit an immediate job on the database

    Hi. I need help using dbms_scheduler to submit an immediate job on the database. Essentially I want to issue a one-time call to an Oracle Stored Procedure - this procedure will then send an email. I've never used dbms_scheduler before, but here's what I have so far.
    So my Program is a stored database procedure named 'TTMS.dropperVacationConflict_Notify', but my problem is that I need to pass 3 parameter values to this job each time I run it. This is what I can't figure out. The procedure expects an 'Id' as number(5), begin_dt as a date, and end_dt as a date.
    How do I pass these values when I run my job? Can anyone help?
    begin
        dbms_scheduler.create_program(program_name=> 'PROG_DROPVACCONFLICTS_NOTIFY',
         program_type=> 'STORED_PROCEDURE',
         program_action=> 'TTMS.dropperVacationConflict_Notify',
         number_of_arguments => 3,
         enabled=>true,
         comments=> 'Procedure to notify PCM of a Dropper Vacation Conflict. Pass in Dropper Id, Begin_dt, and End_dt');
    end;
    begin
        dbms_scheduler.create_schedule
        (schedule_name=> 'INTERVAL_EVERY5_MINUTES',
         start_date=> trunc(sysdate)+18/24,
         repeat_interval => 'freq=MINUTELY;interval=5',
         end_date => null
         comments=> 'Runtime: Every day all 5 minutes, forever'
    end;
    begin
        dbms_scheduler.create_job
        (job_name => 'JOB_DROPVACCONFLICTS_NOTIFY',
         program_name => 'PROG_DROPVACCONFLICTS_NOTIFY',
         schedule_name => 'INTERVAL_EVERY5_MINUTES',
         enabled => true,
         auto_drop => true,
         comments => 'Job to notify PCM of Dropper Vacation Conflicts'
    end;
    /And I use this to execute the job as needed...
    begin
        dbms_scheduler.run_job('JOB_DROPVACCONFLICTS_NOTIFY',true);
    end;
    /
