How to fix the corruption in the logic model?
Hello
I have a logic model created in SDDM 3.1.2.704. I have designed a relational model successfully in the past, but recently when I tried the logic engineer-> relational nothing happens. I get the following entry in the log file:
[AWT-EventQueue-0] ERROR MDBAction - java.lang.NullPointerException
Looking at some other threads, I used the script of processing described here
3.1.3.709: how to check and fix a design may be corrupted?
This does not solve my problem, but the output file (generated when I press the engineer to the relational model button) shows the following exception:
java.lang.NullPointerException

I tried SDDM 3.3.0.747, same result.
I tried to delete entities in the model, 1 at a time, but the problems continues (even when the model will be reduced to any entity at all!)
I tried exporting the model and import it into an empty design. Import fails 'Impossible to generate design' and produced the following exception in the datamodeler.log file:
[Thread-19] ERROR ODExtractionController - error generating Design: Untitled_1

Any help much appreciated. With more than 100 entities and 200 relationships I really want to have to recreate it.
Thanks in advance.
Hello
but the problem continues (even when the model is reduced to no entity at all!)
The error that you stated (in engineering and import) is not reached, if there is none of the entities and attributes - this is a specific error, probably in connection with the use of separate types that are removed from the design.
You can use the search feature to find attributes/columns (logical/relational model) with incorrect data type definition based on the separate type.
And it is better to move it to Data Modeler 4.0 (833).
What to look for (example on the logic model - it is the same for the relational model - column):
(1) to activate the search engine (CTRL-F when logical diagram is active, or the Find icon), switch to advanced mode
(2) for the attribute "object Type":
-check the 'Kind of Data Type' line and put DT as search text
-check the 'Distinct type' line, do not put the text search - it will search attributes without separate type
-change the operand of OR AND expression
3) press the ' search ' button.
If you find some attributes, then you will need to decide what to do with them - to define the data type or delete.
Ditto for the columns in the relational model.

How to fix the microphone in Compaq Presario R3000
Original thread title - how to fix the microphone in Compaq Presario R3000?
Hello
I have a laptop Compaq Presario R3000, and I tried to use Skype on it. Problem is that the other end can't hear me. I tried all the suggestions on the site of Skype to try and attach the microphone. I tried the recorder (click programs, accessories, then entertainment to access), but when I record my voice, nothing, so I guess it has something to do with the microphone. Just to be sure - this model has an internal microphone? What I've read, it seems that it does. I downloaded the updated drivers, so I don't think that's the problem. Any suggestions? I'll try anything now, because I spent about 6 hours online trying to get the microphone to work and so far, nothing. Thank you! PattiHello
1. What problem is only on Skype?
2. were you able to use this microphone earlier?
3 have there been any changes made on the computer before the show?
4. what operating system are you using on your computer?

Problems of updates Windows XP - how to fix the incorrect Windows XP updates KB2633952 keep asking to install? True, it is that it is already installed on your computer. If hide us, an another previous KB2570791 arises in our updates of Windows and asked to install anything, that it was installed... of the questions repeated and very annoying. Help, please!
(Microsoft Answers just sent us message have deleted our previous thread, ask for help!) We are simply not that these problems are problems with Windows XP updates related to DST or not?)
Nadia. PA supporter said that your computer is hacked. He may be right. I can't weigh because I don't know what led him to this conclusion. If your computer is hijacked, then you should address that more that you need to fix this minor update. However, under the resolution of your problem to update, you can try this:
Assume Windows XP
Check the C:\Windows\System32\ directory for the presence of the file tzchange.exe
If the file is not present or if the version of the file is not 5.1.2600.6171 or newer...
Download the update appropriate 2633952 for your platform here:
http://support.Microsoft.com/kb/2633952
Run with - extract switch (e.g., Start > run > "[path to the downloaded file] \WindowsXP-KB2633952-x86-ENU.exe"-x)
Of course, replace [path to the downloaded file] with the path to the downloaded file.
Citations may or may not be required depending on the path. Place the x - out the citations if you use them.
Choose a location for the extracted files (a new folder is recommended)
Locate the extracted files. File tzchange.exe you want and copy it into C:\windows\System32
That rerun Windows Update detection to see if the problem is resolved.

G530 - how to fix the Novo key features?
Hello guys!
Some time ago I completely changed partitions configuration on my laptop, because I wanted to have two systems - Windows 7 (the default) and Ubuntu. Previously, I had an image of the LENOVO_PART (partition Lenovo recovery) by Paragon and burned on DVDs. Its contain images (a recovery key 7) OKR - mbr, boot partition and system (with default settings) file that contains information about the partition sizes and sectors. I deleted all the partitions and create new partitions.
Now I want to restore the original scores, so I restored the partition recovery DVDs, and I put his ID 12 (PTEDIT32) and rebuilt the other partitions on the accuracy of a sector.
Now, I have the following partitions: 1 - start (default is unnamed), 2 - system (default is unnamed), 3 - Lenovo, 4 - LENOVO_PART. Unfortunately the Lenovo System Restore does not start once I pressed the Novo key, so I put the active recovery partition and I can't restore the original mbr, boot, and system. Everything would be fine, but the Novo key doesn't work, then press start the normal system of Windows 7, not the recovery system.
Could someone tell me how could fix the Novo key without the Lenovo service features?
BTW, sorry for my bad English
It should work properly. It seems that there is something wrong with the a key.
at this point, I suggest you call lenovo support line and ship your laptop.

Does anyone have any suggestions?
Thanks in advance for your suggestionsHello!
Open "Command Prompt", right-click the title bar and choose "Properties".
Go to the Layout tab.
In terms of the "Position of the window", uncheck "Let system position window.
Change the Left and Top values to your preference - on my system (left = 290, Top = 0) are ok.
On the same tab, look at the picture under "Overview of the window" to try different values - the window position changes after entering a value in the left text box and pressing the tab key.
I hope that helps!

How to get the logical tab in the main area of 4.1.2 Data Modeler?
I just installed Oracle Developer Data Modeler: Version 4.1.2.895.
I was following section 2.1 development of the logic model
http://docs.Oracle.com/CD/E48219_01/doc.40/e48205/tut_data_modeling.htm#DMDUG36169
I used the example of library. I added the areas.
Then I tried to create the books.
The document says:
- In the main area (right) of the Data Modeler window, click the logical tab.
- Click the icon of the new entity.
But I don't see the logical TAB on the right side at all.
I see the Start Page. On the far right is the browser window. Basically, I see Messages - Log.
On the left side, I have the browser window.
Can someone tell me please how to get the logical TAB in the main area?
Thanks in advance.
Hello!
In the browser with the right button on the logic model and select view.
I hope this helps!

How to create the logical tables &; how to give joints according to obiee 11g?
Hello
I have again to obiee 11g. I want to create the logical tables in MDB layer.
After that I want to give joins according to MDB.
I don't know, how to create the logical tables and how to give joints according to obiee 11g?
Please help me.
Thanks in advance,

Hello
The new logical table is right click on the MDB itself, for the join you generally in the business model diagram (again right click on objects).
Maybe it's better if you start from a kind of tutorial to at least have an overview of what is happening where (layer business and physical layer etc.).
Take a look at what Oracle has available: Oracle BI EE 11 g
