Started this as a normal user.
Path returns:

Code: Select all

C:\oracle\10.2.0\client\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\System32\Wbem;C:\WINDOWS\system32\WindowsPowerShell\v1.0;C:\Program Files\IBM\Director\bin;C:\Program Files\Common Files\IBM\ICC\cimom\bin;C:\Program Files\Windows Imaging\;C:\Program Files\Citrix\System32\Citrix\IMA;C:\Program Files\Citrix\System32\Citrix\IMA\Subsystems;C:\WINDOWS\System32\Citrix\IMA;C:\Program Files\Citrix\system32;C:\Program Files\Common Files\Citrix\System32\;C:\Program Files\Common Files\Citrix\System32;C:\Program Files\Microsoft Application Virtualization Client;C:\Program Files\QuickTime\QTSystem\;C:\Program Files\Unit4\Unit 4 Multivers\bin\
Regkey returns:

Code: Select all

HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE
I also have full control for all users on the ORACLE key, so we might want to exclude that.

2. Does your normal user have access to the PATH variable and to the registry?
1. See http://www.devart.com/forums/viewtopic.php?t=18830
detailed information available in that post.

2. Normal user has been given full control to the Oracle key in HKLM\Software; could you clarify your question about the path variable?
Ofcrouse the user can read the contents of the path variable, otherwise a lot of applications would've stopped working. It's a system variable so the normal user can't change it but definitely read it.

Had this same problem (well, not while developing but while running an application as a standard user).
Turns out.. simply putting the contents of the ORACLE_HOME registry value in an environment variable called ORACLE_HOME (almost obvious ;)) did the trick.
Very weird as the standard user does have access to the full oracle registry key under HKLM, seems like a nice bug to me.

edit: wow, 1 reboot later it stopped working.. great.

Can not load oracle client without local admin rights

Application is running on a Windows 2003 terminal server, with local admin rights the application starts; without local admin rights i get the following error:

Code: Select all

The path environment variable is exactly the same for a local admin and a normal user.

The application allows to specifiy part of the connection string, used the following 2; neither of them work for a user without admin rights; both work for a local administrator:

Code: Select all

Password=****;User ID=***;Data Source=****

Code: Select all

Password=****;User ID=***;Data Source=****;HOME=CLIENT10g
Gave the normal user full control on the oracle client folder (recursively), didn't solve anything.
Other applications with an oracle backend work fine for a normal user; except this one that uses some of your components.


Does anyone have a clue what might be causing this problem?
Thanks in advance.
