Hello people! Now there's more of a comrade helping. Thank you all. : D
Come on:
Cristiano: The application is in Delphi, version 2005. You are not using any connection.
Gilberto: I talked to the responsible programmer about his observation about being a Delphi problem. And he told me he believes it's not Delphi's problem, because even with the problem, the application is running on a machine (Windows 2000 Server and Oracle version 9.2.0.1.0). Only in which has Windows Server 2003 (32 bits) and Oracle version 9.2.0.8.0 that is giving the error. And the schedule is made on the programmer machine. So he gave me the information about the field that is giving the problem: "The value field is a number (12.2).", And that could be some delphi configuration conflict with Oracle for reading this field. That makes sense?
Good, I'm not a programmer, I only take care of the company's infra, and I'm trying to give a personal pro force.

And because of this is that I would like to know if the problem is in Oracle and / or Windows (my responsibilities). If it's in Delphi, then I will not be able to help a lot ... hehehe ... now, would it be missing to load a file or something more from Delphi into the server that does not work the application to work normally? This is because the server does not work the application was newly created. I looked at the server on which the application works correctly and it does not have Delphi installed. But will one day have and was uninstalled leaving some "trail" on the server? I have a little more than 3 months of company and I do not know the history of the servers very well. And I still do not know Delphi to know these details. You understand, right?!

And the worst is that in the link found on the problem they did not get a solution. : LOL: What hardness, is not it?!
Cristiano Again: This dbexpress by a chance is a .dll file? I have been able to make the application run on some company machines by simply copying .dll files from a machine where the application works for what I'm trying to get hit. I ask this question because in the middle of these DLL has a file called dbexpor.dll that if I am not mistaken it was found inside a borland folder. The guy who found the file no longer remembers the name.
That's it guys. Thank you very much for the help of all of you. I hope we can reach a solution.
If you have any idea what I can do here or any questions as you can come to help in the solution, please post, okay?!
Embrace to all,
Ricardo.
