Hi,
Did anybody struggled with RMAN restore doing datafile writes in small 128K
chunks ?
128K is RMAN buffer size which is clearly a torment of underlying storage.
Metallink note 1072545.1. describes various parameters like
_backup_ksfq_bufsz and _db_file_direct_io_count but I haven't got a chance
to test them.
