Hi Jack and List, we have the same situation. Our DB (mainly OLTP) was built with db_block_size 8k and ext2 filesystem (Linux) has 4k block size. AFAIK 4k is max block size for ext2. Do you think it's worth to rebuild the DB with 4k block in order to adjust it to ext2's block size? I know it's quite a difficult question, so I will appreciate your general advices or thoughts. And does anyone know if direct or async options are available on ext2 ? I have little experience of working on Linux.
Thanks, Ed > > Hi > > > I'd say yes.
