Implementing Datawarehousing

Hi,
Please redirect me if I should post this question in Data warehouse forum.
We are planning to implement DW solution in our environment.
Environment would be like,
data from OLTP databases (both 9i and 10g) will be loaded to DWH(10g) in specific intervals (ETL).
Though I have worked in DW environment before I haven't built one from scratch.
Can you please point to documents other than the oracle documentation and any valuable inputs.
We cannot implement Streams since we will be using both versions 9i and 10g for the data source.
Appreciate your help
Thanks

Niki,
You can find tons of good books and articles . What I recommend make a checklist what exactly you want to achieve with DW? e.g. data source, rule for transformation, retention, end user reports, data load performance, query performance, which model you want to support (START or SNOWFLAKE)? Something of hybrid? Volume? Hardware; cpu, storage...? Once you have all the information collected, write high level overview and discuss with your team. This way it will be easy to handle any expectations from mgmt and end users.
Here are some links for more information.

Need help to implement a small data warehouse or datamart

Hi all,
we want to improve our reporting activities, we have 3 production and relational oracle databases and we want to elaborate 1 database as reporting database with historized and aggregated data responding to our reporting needs.
The database we are using are oracle database 10g.
actually we still are doing query to retrieve informations from databases for reporting purpose, but fropm inetrnet search i know that we can implement datamart or datawarehouse to group all aggregated information for reporting.
The information i need are: is there a tools in Oracle for Datawarehousing, Is Oracle Warehouse Builder is the right tools as the sources of our data are all from Oracle database and some flat files.
Could yo advise what i'm going to use for that kind of reporting needs, can i use Oracle warehosue builder to develop ETL ...
Do i need license to use Oracle Warehose Builder
Thanks,

As simple answer to all your questions: YES
Yes, Oracle warehouse builder could be a tool to use.
Yes, Orace warehouse builder needs a license.
Besides that you also need a license for that extra Database.
if you already have that, and you have the queries with which you now retrieve data, you can always choose the cheap way and build materialized views with these queries.
Keep in mind however that a materialized view ( of snapshot ) does not support inline selects.

For OWB and Database and Datawarehouse , I would recomend the Oracle ' Documentation
http://www.oracle.sh.cn/nav/portal_6.htm
Then for tutirials check this (Database and OWB)
http://www.oracle.com/technology/obe/start/index.html
For OBIEE
http://download.oracle.com/docs/cd/E10415_01/doc/index.htm
What is the meaning of OBIEE is it Oracle Business Intelligence Enterprsie EditionYes

Oracle for genetic databases: implementations, overviews?

I'm interested in obtaining information on Oracle
implementations incorporating large volumes of information on &
including: genetic experiments (i.e., gene codes or
identifiers), optics (wavelengths, intensities, etc.) &
increases in cell growth. I'm going to be interested in Oracle
datamining &/or datawarehousing in order to get information out
of this that is not otherwise going to be obvious by looking at
it. Is there a general overview of other implementations of
Oracle (8i or 9i?) like this in the field? I'd be very grateful
for info...thanks,
Noel Whelan

Kevin,
I would definitely focus on 9i as we've added many new features that are relevant for bioinformatics. NEW in 9i:
- Ability to store and search XML data types
- Data mining embedded natively within database (Naive Bayes and Association Rules in 9i, Clustering and Decision Trees (using adaptive Bayes networks) in 9iR2)
- UPSERT (facility to fast update a record or insert a new record). Great for updating life science data.
- IFS forcollaboration and centralized storage of external data types such as powerpoint, word, etc. docs. Users can drag & drop files into IFS for storage, management and access within the database.
- Table Functions to allow piplined "C" procedures for performance improvements of compute intensive operations.
Many useful features are already in 8i (see below) but have been updated or now can be integrated with new 9i features:
- Gateways for native access to external data sources
- External tables for ability to make an external table appear equivalent to a native Oracle table so you can query and perform operations on.
- Oracle Text for efficient text searches
- Oracle InterMedia for storage of image, video etc. data types and ability to perform basic queries and operations on them.
- Oracle Workflow for automating processes within the database. E.g Upload data from GenBank, Mine data to find "targets" and distribute reports to appropriate scientists.
- Oracle Portal to facilitate collaboration and set up company "My.company.com" standard portals with personalized information, reports, etc.
- Oracle Thesaurus so you can define multiple synonyms for a word, gene or pathogen etc.
- Extensible indexing to enable efficient search and retrieval functions for complex domains such as text, spatial, image, chemistry, proteomics and genomics
But, bottom line, I'd jump to the new release. Check OTN and Oracle University for technical information and training materials.
cb
Dear Charles Berger,
How can I see the Internal LInks that you posted?
They look useful as I am a student in bioinformatics currently taking an intro course to database systems and will be implementing a db in Oracle8i.
Also, would you suggest I try to work with 9i and skip 8i. THe problem I have is that all the books and documentation I have is for 8i. Is 8i already history?

Training and Event Management Implementation based on competencies

Dear Friends,
My client is going ahead for Training and Event Managment Implementation. They have a basic requirement to start with and that is :
1) They have done competency mapping for all its employees and they want that the competencies of each employees(along with the skill levels) to be recorded in the system and that has to be the starting point of using Training and Event Management module.
2) They want, if the competencies can flow based on Job/ Position.
3) Some identifier to the competencies, whther it has flowed from Appraisal or any other sources in the Final Training Needs.
Kindly provide me help, as to how I will be able to achieve that and in what Infotypes the data pertaining to Training and Event Managment will be stored.
If u all can kindly share with me the User Manuals and Configuration Docs of Training and Event Management, it will be of great help.
Thank you all.

Hi,
Competencies can be stored as qualifications in PD and then by activation of PD PA intergration can be seen from pa30 infotype 24.
Qualifications can be stored against a Job/Position and are called as the Requirements. They are seen as a separate Tab and to which ever position the person is linked to the corresponding qualifications of the position will appear in the requirements tab.
You can maintain the proficiency and a note along with the qualification when assigned to a person.
Also Appraisals can have qualifications in the template rather than criteria and criteria groups.
Also after training is completed during the follow up we can create an appraisal and transfer the qualifications or simply transfer the qualifications to the employee.

Divya

How can I implement a status bar at the bottom of a resizable application?

Hello all,
I am a JavaFx newbie and I am implementing an application (a Sokoban game), with a menu at the top of the frame and a gaming area covering the rest of the frame. To support the game, I have to load images at certain positions in the gaming area.
The game also includes a level editor with another menubar and where images are set to other positions.
I implemented this in another view, swiching from the game mode to the level editor mode and vice versa is just done by setting the other view visible. Up to now this works, here the important statements building these details:
Group root = new Group();
gameView = new Group(); // for gaming mode
le_view = new Group()   // for level editor mode
MenuBar gameMenubar = new MenuBar();
Menu menuGame = new Menu(bundle.getString("MenuGame"));
... building the menu items and menues ...
gameView.getChildren().add(gameMenubar);
ImageView buildingView[][] = new ImageView[22][22];
for (nCol = 0; nCol < 22; nCol++) {
    for (nRow = 0; nRow < 22; nRow++) {
        buildingView[nCol][nRow] = new ImageView();
        buildingView[nCol][nRow].setX(nCol * 26 + 5);
        buildingView[nCol][nRow].setY(nRow * 26 + 40);
        gameView.getChildren().add(buildingView[nCol][nRow]);
gameView.setVisible(true);
root.getChildren().add(gameView);
... same stuff to build the le_view ...
le_View.setVisible(false);
root.getChildren().add(le_View);
Scene scene = new Scene(root, 800, 600, Color.CORNSILK); Now I want to introduce a status bar at the bottom of the frame, which of course has to follow the bottom of the frame, if it is resized. And of course the menu and the status bar should not grow vertically, if the height of the frame is increased.
The implementation seems to be easy with StackPane for the frame and one BorderPane for each mode.
For the first step I only tried implementing the game mode with only one BorderPane (just setting the menu, the gaming area and the status bar each into a HBox and setting these three HBoxes at the top, into the center and at the bottom). I also tried this via GridPane and via VBox; I always get any erroneous behaviour:
Either the menubar is visible, but the menus do not pop up the menu items, or the anchor point of the menu and of gaming area are set 100 pixels left of the left frame border and move into the frame when the frame width is increased, or the menu is set 20 pixels below the top of the frame, or HBox with the menu grows when the frame height is increased, so that the anchor point of the gaming area moves down.
Can you describe me a correct construction of such a frame? Thanks in advance.
Best regards
Gerhard

Hello Gerhard,
Glad the code helped, thanks for a fun layout exercise.
For the draft code I just pulled an icon off the internet over a http connection.
If you haven't done so already place any icons and graphics you need local to your project, so that resource lookups like:
Image img = new Image("http://www.julepstudios.com/images/close-icon.png");become
Image img = new Image("close-icon.png");then performance may improve.
Another possible reason for your performance problem could be that when you use a vbox, the vbox content can overflow the area of the borderpane center and might be sitting on top of the menu pane, making you unable to click the menu (which is what happens to me when I try that with the draft program with the vbox wrapping mod, then resize the scene to make it smaller). This was a trick which caught me and the reason that I used a Group originally rather than a vbox. I found a vbox still works but you need to tweak things a bit. The trick I saw was that the order in which you add stuff to the borderpane is important. The borderpane acts like a stack where the last thing added floats over the top of everything else if you size the scene small enough. For your project you want the menu on top always, so it always needs to be the last thing added to the borderpane, but when you swap in the level pane for the game pane, then back out again, the game pane can end up on top of the menu which makes the menu seem like you can't click it (only when the scene is sized small enough). It was quite a subtle bug which took me a little while to work out what was happening. For me the solution was to add just one vbox to the center of the border, and then swap the game pane and the level editor in and out of the vbox, that way the center of the layout always stayed behind the menu bar and the status bar.
I added some revisions to reflect the comments above and placed some comments in the code to note what was changed and why.
public class SampleGameLayoutRevised extends Application {
public static void main(String[] args) { Application.launch(args); }
public void start(Stage stage) throws Exception {
    final BorderPane gameLayout = new BorderPane();
    final Group gameView = new Group();
    final MenuBar gameMenubar = new MenuBar();
    final Menu gameMenu = new Menu("Mode");
    final VBox centerView = new VBox();
    centerView.setStyle("-fx-background-color: darkgreen"); // we set a background color on the center view to check if it overwrites the game menu.
    MenuItem playGameMenu = new MenuItem("Play Game");
    MenuItem levelEditMenu = new MenuItem("Edit Levels");
    gameMenu.getItems().add(playGameMenu);
    gameMenu.getItems().add(levelEditMenu);
    gameMenubar.getMenus().add(gameMenu);
    final StackPane levelEditView = new StackPane();
    levelEditView.getChildren().add(new Text("Level Editor"));
    ImageView buildingView[][] = new ImageView[22][22];
    Image img = new Image("http://www.julepstudios.com/images/close-icon.png"); // use of http here is just for example, instead use an image resource from your project files.
    for (int nCol = 0; nCol < 22; nCol++) {
      for (int nRow = 0; nRow < 22; nRow++) {
        ImageView imgView = new ImageView(img);
        imgView.setScaleX(0.5);
        imgView.setScaleY(0.5);
        buildingView[nCol][nRow] = imgView;
        buildingView[nCol][nRow].setX(nCol * 20 + 5);
        buildingView[nCol][nRow].setY(nRow * 20 + 40);
        gameView.getChildren().add(buildingView[nCol][nRow]);
    final VBox statusBar = new VBox();
    final Text statusText = new Text("Playing Game");
    statusBar.getChildren().add(statusText);
    statusBar.setStyle("-fx-background-color: cornsilk"); // we set a background color on the status bar,
                                                          // because we can't rely on the scene background color
                                                          // because, if the scene is sized small, the status bar will start to overlay the game view
                                                          // and if we don't explicitly set the statusBar background the center view will start
                                                          // to bleed through the transparent background of the statusBar.
    gameLayout.setCenter(centerView); // we add the centerview first and we never change it, instead we put it's changeable contents in a vbox and change out the vbox content.
    gameLayout.setBottom(statusBar);
    gameLayout.setTop(gameMenubar);   // note the game layout is the last thing added to the borderpane so it will always stay on top if the border pane is resized.
    playGameMenu.setOnAction(new EventHandler<ActionEvent>() {
      public void handle(ActionEvent event) {
        centerView.getChildren().clear(); // here we perform a centerview vbox content swap.
        centerView.getChildren().add(gameView);
        statusText.setText("Playing Game");
    levelEditMenu.setOnAction(new EventHandler<ActionEvent>() {
      public void handle(ActionEvent event) {
        centerView.getChildren().clear(); // here we perform a centerview vbox content swap.
        centerView.getChildren().add(levelEditView);
        statusText.setText("Editing Level");
    playGameMenu.fire();
    Scene scene = new Scene(gameLayout, 800, 600, Color.CORNSILK);
    stage.setScene(scene);
    stage.show();
}Other than that I am not sure of a reason for the slowdown you are seeing. In my experience JavaFX has been quick and responsive for the tasks I have been using it for. Admittedly, I just use if for a bunch of small trial projects, but I've never seen it unresponsive for a minute.

Error while activating the Implementation class of a BADI ?

Hello,
I am trying to activate a BADIi but its implementation class(ZCL_IM_DSD_ADD_CUST_IN_DNL) is not getting activated and giving the following object error on activation.
CPUB ZCL_IM_DSD_ADD_CUST_IN_DNL
and it says that "INCLUDE report "ZCL_IM_DSD_ADD_CUST_IN_DNL====CL" not found , where "DSD_ADD_CUST_IN_DNL" is the Impl. name of the definition "/DSD/ME_BAPI" implementing the interface "/DSD/IF_EX_ME_BAPI".
what am i missing here. Big time help will be extremely appreciated ..
Thanks a ton.

Hi,
I had a quick qn,
Normally, the implementation name should start with Z. Can you create using the name 'DSD_ADD_CUST_IN_DNL' ? or are you using any access key (SSCR)?
For the infm, I have just tried to create one Z implementation in my system and it works fine. Could you please delete the current implementation and try it once again ?

Weaknesses I've come across in the Oracle XML/XSL implementation

Weaknesses I've come across in the Oracle XML/XSL implementation
NOTE: I think Oracle is a fantastic database and the XML implementation is lovely to use - also I know these are not limited to XE and also that some are fixed in 11g enterprise however I'm not sure if all are so I am posting here in the hope that Oracle will include fixes for all if any have been missed
1. getclobval() returns a spurious carriage return on end of the value returned
2. extract does not handle mixed content tags well (for example it simply discards tags that only have whitespace between them
3. XSL: using a xsl:number level="multiple" with anything beyond a simple count= xpath value crashes the database completely
4. XSL: insists on pretty printing output XML which is extremely odd behaviour and causes problems when dealing with mixed content

Another weakness I've seen is with the appendchildxml function and mixed content xml - it appears to likewise pretty print XML causing the injection of carriage returns and whitespace into mixed content nodes

How to find out the user exit is implemented

Hi All,
Kindly let me know the process to be followed to find out the User exit is implemented in SAP system.
I have seen many senriors suggestions for some treads to check if there is any Exit is implemented in the process when the system is behaving differently rather standard.
Is it the only way with help of ABAP'er we can find out or the functional consultant also can find out through some procedure?
I tied in google for this doubt, but i could not get the relavant answer.Pleaea execuse me if this already answered.
Thanks,

Hi Krishna/TW,
Thank you for your immediate replies. Sorry i think i have not explained correctly my requirment.
Let me explain my requirement once again.Let us say Comapny has implemented one Exit in the project, now i want to find out what exactly the Exit was implemented.
Example: In STO process user is able to increase the qty in delivery. As per the client requriement system should not allow.
This is not possible in standard to control even after maintainig check over delivery field in 0VLP.
For this comapny has already implemented one enahnceament.
User Exit : USER EXIT_READ_DOCUMENT
Program: MV50AFZ1
like this when any one joined in the project we do not know what are all the Exits are implemented in the SAP system where we are working.
So if i want to find out if there is any Exit or enhancement implemented, what is the process to find out?
I hope now am clear with my requirement.
Thanks in advance.
