Oracle Client software requires that you give the Authenticated User
privilege to the Oracle Home by following these steps:
1. Log on to Windows as a user with Administrator privileges.
2. Launch Windows Explorer from the Start Menu and navigate to the
ORACLE_HOME folder. This is typically...
- the "Ora92" folder under the "Oracle" folder
(i.e. D:\Oracle\Ora92) in Oracle9iR2
or
- the "Client_1" folder under the "Oracle\product\10.1.0" folder
(i.e. D:\Oracle\product\10.1.0\Client_1) in Oracle10gR1
or
- the "Db_1" folder under the "Oracle\product\10.1.0" folder
(i.e. D:\Oracle\product\10.1.0\Db_1) in Oracle10gR1
3. Right-click on the ORACLE_HOME folder and choose the "Properties" option
from the drop down list. A "Properties" window should appear.
4. Click on the "Security" tab of the "Properties" window.
NOTE: If you are running Windows XP and do not have a "Security" tab
please do the following:
(a) Open "Folder Options" in your Control Panel.
(b) Choose the "View" tab.
(c) Under "Advanced Settings" uncheck the option "Use simple file
sharing (Recommended)".
The "Security" tab should now be available.
5. Click on "Authenticated Users" item in the "Name" list (on Windows XP
the "Name" list is called "Group or user names").
6. Uncheck the "Read and Execute" box in the "Permissions" list under the
7. Re-check the "Read and Execute" box under the "Allow" column (this is
the box you just unchecked).
8. Click the "Advanced" button and in the "Permission Entries" list make
sure you see the "Authenticated Users" listed there with:
Permission = Read & Execute
Apply To = This folder, subfolders and files
If this is NOT the case, edit that line and make sure the "Apply onto"
drop-down box is set to "This folder, subfolders and files". This
should already be set properly but it is important that you verify this.
9. Click the "Ok" button until you close out all of the security properties
windows. The cursor may present the hour glass for a few seconds as it
applies the permissions you just changed to all subfolders and files.
10. You must REBOOT YOUR COMPUTER to assure that these changes have taken
effect. Failure to do this can prevent this procedure from working!
11. Re-execute the application and it should now work.
NOTE: If the problem is still present after following steps 1-11 and
rebooting your computer in step 10 you should perform the following
two additional permissions settings at step 8 as described below.
This may be necessary due to permissions that have been configured
beyond the standard permissions setup when the OS was originally
installed:
12. If the problem is still present, go back through these same 11 steps
above, but when performing step 8 additionally check both boxes entitled
objects. Include these with entries explicitly defined here."
