A geometry compatibility check verifies whether a database dump can be loaded successfully into the target database.
Checks are performed both interactive and noninteractive modes. The rules that verify this compatibility are:
The size and the order of the data and log fragments must match. If two or more consecutive fragments are of the same type (data or log), the sizes for these consecutive fragments are combined together by the restore utility before a comparison is done between the dumped database and the target database.
The size of all fragments before the last fragment for the target database must match exactly with the size of the dumped database. The last fragment of the target database can be bigger than the database that is dumped. There may be extra fragments in the target database after matching all fragments in the dumped database.
