If you have ever installed an instance of Oracle WebCenter Content on a Windows server you probably stepped into this error:
The weblayout directory is on a filesystem with 8dot3 semantics. Legacy 16-bit 8dot3 filenames conflict with revision labels and will cause file loss. Disable 8dot3 semantics by running "Installer DisableNtfs8dot3" and then restarting Windows.
This can be solved in two ways:
1)Using Oracle suggested procedure
This is done running Installer.exe with DisableNtfs8dot3 parameter.
To do this open command prompt (Start -> Run -> cmd) and go to:
In my server it was:
2)Editing a registry key
Open regedit (Start -> Run -> regedit) and go to:
Edit NtfsDisable8dot3NameCreation key and change its value to 1 (default value is 2).
After this restart UCM instance (if you edit registry also a server reboot would be necessary) and alert message will disappear.
