How to generate OLAP DML code or CWM2 code outside of workspace manager 10g

I am using AWM 10.2, where I am creating cubes and dimensions etc. I can export the workspace into XML, but i want more, i want to generate definition of my OLAP, i want to see OLAP DML code for creating my workspace. Anybod has an idea ?
1) How can I generate OLAP DML definition of my existing workspace ?
Second thing is, that I really don't understand the concept of CWM2, what is this good for ? Is my AWM automatically generating some CWM2 statements and executing it ? Where can i see them ? Why do i need another logical CWM definition when I have regular OLAP definition ?
2) What is the role of CWM2 in OLAP ? How can i generate CWM2 code outside of my existing workspace ?

The DESCRIBE command will give you the definition of the object but it won't tell you anything about how objects should be populated. The API for Analytic Workspaces (AW/XML) takes responsibility for both object creation and object maintenance.
What is it that you might want to accomplish by using OLAP DML to create the objects?

How to generate Flow Chart from Program Source Code easily and automatically.

It is very crucial to have a clear mind when faced with abstract codes for software engineers and program developers. As always, the programmers have had an overall structure in your mind and then process the design with source code. The structure can somehow be so complex that it becomes hard to cope with gradually. More often than not, you will get stuck when you process to some extent. However, codes can’t speak and present themselves in a straightforward way. You are eager to find out a straightforward layout to transfer those abstract codes to visible flowchart, aren’t you? Do you know there's code to flowchart software tools online? This tool can help you make a flowchart from source code automatically, here I will introduce you a great code to flowchart converter software.
Code Flowchart Creator is professional source code to flowchart software tool. This software is designed for programmers or document writers, and its main function is to generate flow chart from source code such as C, C++, VC++ (Visual C++ .NET) and Delphi (Object Pascal) programming files. It helps users to understand complex program structures by visual diagrams. When users are editing the source code, it can make a flowchart or NS chart according to that code, the source code will be analyzed to build a visible flowchart that can help users get familiar with the process of the program. The created flowchart can be exported as Visio/Word/BMP files. And it works well on all Windows OS, especially on Windows 7.
Below is simple guide on how to use the Flowchart Converter. Step 1: Free download the setup file on official website: http://www.flowchart-creator.com Step 2: Install it on PC and startup the Flowchart Creator Step 3: Open a source code file and it will automatically generate the Flow Chart on right Window.

The generated flowchart can be used to review source code. It will help examine the whole process of a program and check where errors exist when users are verifying source codes. You will never be worried about the complex program structure with the powerful code to flowchart creator tool.

Dear Chuck,
I have used Google and other search engines intensively since years. What I need (and this is why I've opened this thread actually) is a suggestion for a product from someone that has already used it. That could also save me time instead of searching, installing, trying, and eventually deinstalling at random. After all, the forum should allow to exchange knowledge and experience with people having similar interests.

How to deploy OLAP DML scripts or programs?

Once finishing developing a set of OLAP DML scripts in AWM
How can I deployed them to production environment?
Is there a command-line equivalence for OLAP worksheet?
( something like sqlplus @file, which execute
a set of commands store in file )
Thanks
Warren

OLAP Worksheet found within AWM is a command line interface to Oracle that you can use with Oracle Database 9.2 or later to do the following:
* Execute most OLAP DML commands
* Edit OLAP DML programs, formulas, aggmaps, and models
* Execute SQL statements
To execute a saved OLAP DML program simply type the name at the bottom input pane in OLAP Worksheet and and hit the Enter key. Also, you can invoke an OLAP DML program that does not return a value by using the CALL command. Please refer to the OLAP DML Language Help found in OLAP Worksheet or the following Developer's Guide to the OLAP DML:

How to enable olap option in oracle enterprise edition 10g?

what are the settings/steps one should take in enabling OLAP option in oracle enterprise edition 10g?
If we have an installation of Oracle EE 10g,how can we know that OLAP is enabled or not?
Can anyone throw light on OLAP_TABLE function?
In Analytic Workspace manager 10g,i have created a workspace ,under that i am having some dimensions,cubes,as well.
After mapped to source table,and maintained,when i do a right click on measures, to view data, i get a error ORA-06553:PLS-222:no function with the name 'OLAP_TABLE' exists in this scope

The Export function is disabled when the responsibility is opened initially .
When we enter into a specific form its automatically enabled .

How do I view data from OLAP DML program or statement?

Hi
I'm struggling to find any information on this topic anywhere on the net:
How to view data produced by an Oracle OLAP DML program or statement.
Background :
I am using the latest AWM to create and maintain dimensions, cubes and measures. However, I've noticed that AWM, Discoverer OLAP, BI Beans, Excel Plug-In et al only provide a fixed set of formula and expressions.
For example, I wanted to created a Standard Deviation (STDEV) on measure. After much searching I learnt that I could do this by creating a custom measure in AWM by importing a measure defined in an XML dcoument as it's not provided by AWM. The output in Discoverer OLAP on the surface seems to give the correct results, however when drilling from high level to lower level of time time dimension hierarchy Discoverer includes the parent value in the calculation and renders the values incorrect.
My alternative is to use OLAP DML, as it provides a richer range of formuale and calculations possibilities and I was hoping to use this functionality to do create the measures. I have the distinct impression, however, that OLAP Worksheet is the only interface out there to do this.
It seems very primitive and limited with regards to data output, almost like SQL*Plus in many ways.
The burning questions I have are :
1) Do I need to write DML programs to perform these custom measure calculations and add them to cubes or do I import the custom measures via AWM and XML?
2) If the answer to question 1 is DML programming, is there a way of viewing the OLAP data output through a GUI interface without embedding the statements in SQL.
3) Has anyone experienced or noticed the same problem with Discoverer OLAP, AWM Viewer that I mentioned above? i,e, statistical functions performed on whole dimension hierarchy rather than lower levels.
I'm hoping someone out there knows what I am trying to do or get at. Keith, any ideas or suggestions?
Thanks
Kind Regards
Greg

Hi Greg,
There are two ways to achieve what you want. Both require the use of custom calculations which cannot be created via the calculation wizard within AWM. To do this the easiest way is step outside of AWM and use the Excel Calculation utility that is on the OLAP OTN home page:
Creating OLAP Calculations using Excel
http://download.oracle.com/otn/java/olap/SpreadsheetCalcs_10203.zip
Readme
http://www.oracle.com/technology/products/bi/olap/OLAP_SpreadsheetCalcs.html
(Oracle OLAP DML Reference contains a list of all the OLAP functions that can be used to create a custom calculation. http://www.oracle.com/technology/products/bi/olap/OLAP_DML_10.2.zip)
The Excel tool lets you assign your own formula to a measure and then uploads that measure definition into your AW. It is possible to import a custom calculation template into AWM using the menu option on the Calculated Measure node of each cube, but it is safer to use the Excel Worksheet as this directly uses the public XML API and is always best to use a public API rather than hacking XML templates.
There are two types of custom calculation:
1) Formula: using a formula you can directly call any of the OLAP functions. For example to create a measure that returns the standard deviation for a measure then you would enter the following as the formula for your calculated measure:
stddev(sales_revenue, time)
The easiest way to test if the measure is working as expected is to use the data viewer within AWM.
2) Programs - if the function you need is not provided or you want to do special processing to return a result you can create an OLAP DML program which can return a result. To do this use OLAP Worksheet to define the program and add a datatype to the DEFINE statement, such as :
DEFINE PRG_SD_SALES PROGRAM DECIMAL
In the program return the value you have calculated within your program. Within the program you can do just about anything but be aware that your program is going to fire for every cell within your virtual cube so it must be efficient and fast to execute. For a measure then you would enter the following as the formula for your calculated measure:
prg_sd_sales(time, products, geographies, channels).
The actual program code would look something like this:
DEFINE PRG_SD_REVENUE PROGRAM DECIMAL
PROGRAM
argument T_TIME TIME
argument T_PRODUCT PRODUCTS
argument T_GEOGRAPHY GEOGRAPHIES
argument T_CHANNEL CHANNELS
variable D_RETURN decimal
TEMPSTAT TIME, PRODUCTS, GEOGRAPHIES, CHANNELS
do
limit PRODUCTS to T_PRODUCT
limit CHANNELS to T_CHANNEL
limit GEOGRAPHIES to T_GEOGRAPHY
limit TIME to T_TIME
limit TIME add descendants using TIME_PARENTREL
limit TIME keep TIME_LEVELREL 'CAL_MONTH'
D_RETURN = stddev(SALES_REVENUE)
doend
return D_RETURN
END
This code computes a standard deviation the all months within the specified time range, at year level for all 12 months, at quarter level for the three months within the quarter ans returns NA at the month level.
As the code executes within a implicit loop you can only change the status fo dimensions that for part of that implicit by using the TEMPSTAT command. To test the program at the command line use the OLAP Worksheet and the SHOW command to just return one cell of data, DO NOT SIMPLY USE THE RPR COMMAND because you will have to wait for the whole cube to be returned. If you want to use the RPR command make sure you limit your base dimensions first! You can use PRGTRACE to debug your program code it is not working as expected. Again, the easiest way to test if the measure is working as expected is to use the data viewer within AWM, although this will not return debug information so send all your debug output to a file to capture any errors and/or trace the execution flow.
Hope this helps

How to generate selection change event through code in JTree?

I am developing an application which downloads the file from other system and adds it into the tree. On selecting any file in the tree I m displaying it's contents. But now i am trying to display the contents of downloaded file as soon as it's download completes. Here i am not getting the way to how to generate the event as the download completes, because i tried that setSelectionPath(TreePath path), but it also don't generates the selection change event. Is there any other way to do so?

Put null in place of oldLeadSelectionPath. From the API for TreeSelectionEvent:
protected TreePath oldLeadSelectionPath:
leadSelectionPath before the paths changed, may be null.
I'm at the office and can't try out anything, so please let me know whether that works for you.

edit Or it may be easier to put all code from your valueChanged (...) override in a new method and invoke that method both from valueChanged (...) and wherever else you need.

How to generate code in Sun Java Studio Enterprise 8

Do I miss something? I can�t find how to generate code from UML model, which is not reversed from code. Documentation also does not speak about this.
Code update works fine if project is reversed from code, but if in such reversed model I create new class it does not appear in code and context action "Generate Code" is missing for such class.
I use Sun Java Studio Enterprise 8

Thank you for replay, may steps are same:
1. I have created Java Project With Existing Source
2. selected directory with code (not whole project but directory with java classes)
3. After that I have created UML Java Specific project and
4. Associated UML project with previous created java project
5. I have selected "Code Generation" check box
6. Classes from java project were reversed into UML model.
7. After that I have created new class in java project.
And there is no Generate code action in this class context menu, also this class do not appeared in code automatically.
From UML project properties it is shown that UML project is associated with proper java project)
Same is with Java Application project associated with UML java project.
Documentation do not talks more about this. Only same steps. It looks like code generation should be working but it isn't. I'm I only one who face this problem, or do smth wrong?

Urgent How to generate a random code such as registration code?

I would like to ask that how to generate a random code?
For example, when you register a E-mail account, you need to enter the code for activation. I would like to create a java Bean to do this job. Would you help me?

In fact, I would like to set a 10 digi codes randomly (such as FH654CS081, MKO624VG9f) for user input when they register the forum account. This random code will be sent to the user's email. User have to input this code to a JSP web site. Also, the code which is inputed by user will be matched with the database. If user input success, the forum account will be activated.
By generating this 10 digi codes, I want to handle this generation by using java bean.
1) Any thing else i need to import ? (such as <% page import="java.......?")
2) Any functions can handle this task?
3) Any example can be my reference?
Thank you very much

How do I edit the file created by code generator?

hi all,
I want to modify a java file that is generated when you create the webdynpro, but I can not change.
// This file has been generated partially by the Web Dynpro Code Generator.
// MODIFY CODE ONLY IN SECTIONS ENCLOSED BY @@begin AND @@end.
// ALL OTHER CHANGES WILL BE LOST IF THE FILE IS REGENERATED.
how can I disable the file to modify
thanks!

Hi Pablo.
There's no way to modify it, NW2004s and its IDE has a code compilation based in some internal scripts based on eclipse plugin architecture.
In your code you must consider this.
1 - Try to find in your declared methods, importing directives, packages declarations some like this:
// This file has been generated partially by the Web Dynpro Code Generator.
// MODIFY CODE ONLY IN SECTIONS ENCLOSED BY @@begin AND @@end.
// ALL OTHER CHANGES WILL BE LOST IF THE FILE IS REGENERATED.
package com.sap.teste;
// IMPORTANT NOTE:
// ALL IMPORT STATEMENTS MUST BE PLACED IN THE FOLLOWING SECTION ENCLOSED
// BY @@begin imports AND @@end. FURTHERMORE, THIS SECTION MUST ALWAYS CONTAIN
// AT LEAST ONE IMPORT STATEMENT (E.G. THAT FOR IPrivateTesteApp).
// OTHERWISE, USING THE ECLIPSE FUNCTION "Organize Imports" FOLLOWED BY
// A WEB DYNPRO CODE GENERATION (E.G. PROJECT BUILD) WILL RESULT IN THE LOSS
// OF IMPORT STATEMENTS.
//@@begin imports
import com.sap.teste.wdp.IPrivateTesteApp;
import com.sap.myimport.MyClass;
//@@end
//@@begin
//@@end
it means that between begin and end...you can add what you want..and the code will not be removed after class compilation....
//@@begin javadoc:wdDoExit()
/** Hook method called to clean up controller. */
//@@end
public void wdDoExit()
//@@begin wdDoExit()
//@@end
int this case too....if you implement something between //@@begin and //@@end in the method scope...all part of your code will be surely safe.

How i can generat VHDL or Verilog code from labview code

how i can generat VHDL or Verilog code from labview code ( i have a labview code and i want to convert it to VHDL or Verilog code how i can do that )

Mouath,
There is no feature in LabVIEW to export your VIs as VHDL files. You are able to include your own HDL in your LabVIEW VI (using the HDL node). I encourage you to provide your feedback related to this issue at ni.com/contact. The product suggestion submitted are taken seriously and reviewed by National Instruments.

OLAP DML: How to specify multidimensional QDR(qualified data ref) for Model

Hello,
I'm discovering Oracle OLAP DML and having a hard time understanding how to formulate multidimensional expressions in models.
In a setting with a solution variable (eg. result), I can do:
LIMIT account TO sales.internal
result = result(account '3xxx', consolidation 'internal')
but what to do within a model?
DIMENSION account consolidation
sales.internal = ??? (QDR to limit account to '3xxx' and consolidation to 'internal')
No examples in the OLAP DML doc use multidimensional QDRs in models, and I get a syntax error trying with (account '3xxx', consolidation 'internal').
Any suggestions?
Regards, Hans Henrik

It should look something like this :
MODEL
result(account 'sales.internal') = result(account '3xxx' consolidation 'internal')
END
No dimension statement is needed for variable equation.
