Novell ZENworks 7.5 Asset Management - ZAM7.5
The ZAM 7.5 defaults to an .ora extension for the Oracle database during the install.
If the customer changes the database extension to .dbf, the install will fail to create the database and generate a dbinit error.
There is not any functional difference between extension names.
Novell has not officially tested using any extension other than .ora and recommends the use of that extension.
No issues are expected if the database is later renamed to a .dbf extension, but this not officially supported.
