Extents archived automatically by the AI File Management utility daemon are assigned an unique file name by the archive process. The archived file name is comprised of a combination of file names and sequence numbers that identify the source of the archive file and the state of the source database at the time of the archive. The elements are:
The full file specification of the source database, with a "~" replacing the directory separator
In Windows, the colon (:) following a drive letter is replaced by an exclamation point (!)
The AI Sequence number or file number
The name of the AI extent
The elements are concatenated into a file name as shown:
directory~spec~database.ai-sequence.extent-name
