load database has limitations when used with an archive database.
The database dump for an archive database is required to be a disk dump on a file system mounted on the local machine. This can be local storage or NFS storage. load database ... at <remote server> syntax is not supported, nor are database dumps on tape.
Cross-architecture loads are not supported. The database dump and the load database command must be performed on the same architecture with respect to byte ordering.
The dumped database must have the same page size as that used by the server that is hosting the archive database.
The major version of the server on which the dump was taken must be earlier than or equal to the major version of the server hosting the archive database.
The character set and sort order on the server on which the database dump was taken must be the same as the character set and sort order of the server hosting the archive database.
