RMAN-05601: Failed to restore original settings to server parameter file
Reason for the Error
An error was received while duplicating the database after the server parameter file was modified by RMAN. An attempt was made to restore original settings to the server parameter file, but the original error was such that it was not possible to restore the settings.
Solution
Before reattempting database duplication, the server parameter file needs to be fixed manually with the original values.
