RE: Raw vs Cooked space?

Paul, I don't see any drawback what-so-ever in using raw devices. Backup? Use informix ontape to backup with the engine running. When there are no raw device available (Linux, 2.2.*) using the block devices is faster, anyway. If you have a disk partition > 2GB you should create more than one chunk, with the offset option. regards--- Diego Mezzera. ----- Mensaje original ----- De: Paul Jazwierski <uszko@earthlink.net> Para: <informix-list@iiug.org> Enviado: Jueves, 27 de Enero de 2000 02:09 p.m. Asunto: Raw vs Cooked space? > Can anybody point me to any factual information about the > benefits/drawbacks of using raw vs cooked spaces.
