Oracle Error Message
ORA-45907: instant restore of data file string failed
Reason for the Error
During an instant restore, it was not possible to initialize the destination data file. There might be other messages on the error stack or alert log or trace file that indicate the specific reason for the failure. One common reason for this message is that the instant restore feature is disabled in this database.
Solution
Check the other messages. If the situation cannot be resolved then request a regular, not instant, restore.
