I can't create Entity Data Model Class directly from database

I have just installed odac beta (ODAC1120250Beta_EntityFramework) and Orace XE 11g for test.
I have Visual Studio 2010 on Windows 7 32bit.
The problem is that after updating odac I can't create ADO.NET Entity Data Model class. If I try, VS2010 wizard makes me choose if I want to generate from db or create an empty model. If I choose to generate from database, the next window disappers making me return to VS2010.
The workaround is to create an empty model and then update model from database. In this way it works.
Anybody has experimented the same?...
Best regards
Francesco

A couple of things you could try:
1. Install SP1 for Visual Studio 2010.
2. Do you already have an Oracle connection created in server explorer? If not, try creating one and then create the model.

Data Modeling for a Small Database Tutorial - understanding "Creating Relations Between Entities" part

I am trying to understand and make use of Tutorial: Data Modeling for a Small Database
During this tutorial I'm supposed to make Transactions Entity containing two attributes that will refer to Patrons (patron_id) and Books Entities (book_id) (2.1.4)
Later, I'm adding two one-to-many relations that duplicate mentioned attributes in Transactions Entity (patron_id1 and book_id1). (2.1.5)
So here comes my questions: what's the purpose of creating those attributes in point 2.1.4 if they're then duplicated in paragraph 2.1.5?
If it might be crucial, i'm using Oracle SQL Developer Data Modeler Version 4.0.0.825 Build 825 on jdk1.7.0_25.
Bonus question: How to turn on attributes types on Logical Diagram? I can't find corresponding option anywhere...
I would be really grateful for every answer and for every trick!

You are looking at release 2 documentation. I checked 3.3 and 4.0 EA3 and the tutorial has been corrected You may want to download the latest version and use that documentation.

Can we create entity object based on a text file on the OS?

I understand you can interface with files using webDAV. Can we just create a entity object with source to a text/xml file on the OS instead of a table?

Have a look at the URL data source (under new->business tier->web services) - it allows you to create a data control based on an XML or csv file.

You can also create a data control based on a Java class that interact with a file.

Unable to Create New Data Model

Hello all,
I have been using BI publisher 11g for sometime but at best can be treated as a newbie. I was able to create New data models, reports, layouts etc till sometime ago.
Now when I try to create a New Data Model I get an error message saying
Unable to load ~weblogic/usr/temp/xxxxxxxx.xdm
I click on Ok and create my data set using the SQL query.
Now when I try to generate a sample xml I get the following error message:
org.xml.sax.SAXParseException: : XML-20108: (Fatal Error) Start of root element expected.
I understand something has changed in the server but I cannot pin point what and where.
Any help will be highly appreciated.....
Thanks,
Geetesh

The JDK/Java that ODI using should be 64bit if ODI 11.1.1.6 is 64 bit. (I think JDK 1.6 is recommended for this ODI version)
Also, for which technology you are creating a data server ? and what error message you are getting while creating it ?
Thanks,
Santy.

Oracle Entity Framework: some tables won't update the entity data model

I've successfully connected to an oracle database, and I've set up an entity data model project in Visual Studio 2010.
Using "Update Model from Database" on the EDMX file, some tables that I select are imported, but others do not appear. Is there something about these tables that prevents them from being imported?
Thanks

When I tried this the first time, I missed a message that answers my question:
The table/view does not have a primary key defined and no valid primary key could be inferred. This table/view has been excluded. To use the entity, you will need to review your schema, add the correct keys, and uncomment it.
Another table was brought in because the entity model managed to infer a primary key:
The table/view does not have a primary key defined. The key has been inferred and the definition was created as a read-only table/view.

Can´t create a date attribute for basic asset

Hi
I created a basic asset where I want to have a date attribute to pick up a date for calendar.
My question is: How can I create a date attribute for a basic asset? For what I understand I have to create an element attribute in my descriptor file like this
<PROPERTY NAME="imagedate" DESCRIPTION="Image date">
<STORAGE TYPE="TIMESTAMP" LENGTH="8"/>
<INPUTFORM TYPE="ELEMENT" WIDTH="24" MAXLENGTH="48" REQUIRED="NO" DEFAULT="" INSTRUCTION="Format: yyyy-mm-dd hh:mm"/>
<SEARCHFORM DESCRIPTION="Image date" TYPE="ELEMENT" WIDTH="48" MAXLENGTH="128"/>
</PROPERTY>
Then, when I create a new instance of this asset, this attribute appears with this error:
Date: Unable to find element OpenMarket/Xcelerate/AssetType/Oportunidade/ContentForm/imagedate
But the element (imagedate.xml) is there!!
I request help.

It seems that the table does not have the entries, maybe b/c we are on R3 4.7. Could you tell me what the entries are suppossed to be to allow the Asset and Cost Center lookup? The search does work for WBS element though and I don't see anything specific to WBS element in that table. In any case if you know the entries that would be great, also this table is not modifiable via SM30, here are the entries that I have in that table.

How can we create a data source on structures

Hi,
   How can we create a data source on structures.
Regs,
abdul

Abdul,
    Welcome to SDN!
    We can't create Datasource using Strcutres. We need to have base tables.
    For Function Module Extractors, we will create strctures. We will use these strctures as Extract Structures. But, we will get the data from Base tables only not from Strcutures.
Strctures won't contain data.
all the best.

"Can't create part for model element: null"

Hello Colleagues,
I am developing a Widget using Eclipse. Yesterday I closed the project and today I tried to open it again. For some reason, it seems that the config.xml file is corrupted. When I open the editor, I receive the following error:
"Can't create part for model element: null"
I tried to find out where in the xml file is the error, without success.
Do you have any clue to get it solved?
If you need some more information, please let me know.
Thank you very much!
Rafael

Hi Rafael,
What version are you using? I have had similar problems in the past. Worst case I had to recreate the widget and copy the coding across.
Can you send me the project file, I will understand also if you do not want to, I will try it on my machine.
Regards
John

Can i copy the data model from report?

RegardsCan't you save the Report1 as Report2 (by doing this you will have your Data Model and everything from Report1 will be copied to Report2) and do those little modifications in the Report2.
OR
Take the SQL statement from the Report1 and use that in the Report2.

Copy data models and reports from BW 3.1 to NW 2004s

Hi experts,
Our client has two BW servers: BW 3.1 and BI 7. BW 3.1 contains lots of data models and reports. And the BI 7 server is newly installed.
Now we want to copy these data models and reports from BW 3.1 to the new BI 7 server. Are there any solutions for this?
Thank you very much in advance.

Hi Frank,
Sounds like a cross version transport is needed.
This is a solution we have used to do what you want to do:-
Create and release a transport as per normal.
Copy and transport the files from the source system (BW 3.1) e.g /usr/sap/trans/data & /usr/sap/trans/cofiles to the same folders on the target system.
Basis help is needed here.
From here onwards using stms_import should help you in the normal manner.
Works a treat.
Have transported the following all correctly appearing as 3.x data models in NW2004s.
DSO objects.
Cubes
Transfer/Update rules
Reports.
Cheers,
Pom

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap?

How can I Cache the data I'm reading from a collection of text files in a directory using a TreeMap? Currently my program reads the data from several text files in a directory and the saves that information in a text file called output.txt. I would like to cache this data in order to use it later. How can I do this using the TreeMap Class? These are the keys,values: TreeMap The data I'd like to Cache is (date from the file, time of the file, current time).
import java.io.*;
public class CacheData {
public static void main(String[] args) throws IOException {
String target_dir = "C:\\Files";
String output = "C:\\Files\output.txt";
File dir = new File(target_dir);
File[] files = dir.listFiles();
// open the Printwriter before your loop
PrintWriter outputStream = new PrintWriter(output);
for (File textfiles : files) {
if (textfiles.isFile() && textfiles.getName().endsWith(".txt")) {
BufferedReader inputStream = null;
// close the outputstream after the loop
outputStream.close();
try {
inputStream = new BufferedReader(new FileReader(textfiles));
String line;
while ((line = inputStream.readLine()) != null) {
System.out.println(line);
// Write Content
outputStream.println(line);
} finally {
if (inputStream != null) {
inputStream.close();

I don't understand your question.
If you don't know how to use TreeMap why do you think a TreeMap is the correct solution for what you want to do?
If you are just asking how to use TreeMap then there are PLENTY of tutorials on the internet and the Java API provides the methods that area available.
TreeMap (Java Platform SE 7 )
Are you sure you want a map and not a tree instead?

How can I create a master PDX that pulls from multiple other PDXs?

I process aviation maintenance manuals, with the individual manuals having their own PDX. How can I create a master PDX that pulls from the individual PDXs?
I have access to myriad versions of Windows and Acrobat so there's that...

I’ve got 100s of manuals each with their own PDX. I’ve been asked to create a master PDX that in effect combines all of the individual PDXs into a single (cross-manufacturer, cross-fleet, cross-manual-type) searchable PDX that can be easily updated.
