[opensuse] async I/O on SuSE 9.3 (aio)
does anybody have any experience running aio on SuSE? how do I make it happen? this is to connect it to Oracle 10G (10.2). A-sync I/o's is default for Oracle. is it stable? do I need to patch the kernel? --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-unsubscribe@opensuse.org For additional commands, e-mail: opensuse-help@opensuse.org

If you run that Oracle in production, run it on SLES9, not on SUSE Linux 9.3. SLES9 has AIO and you don't need to do anything, because it's default. So I guess 9.3 has it too. Why don't you subscribe to suse-oracle@suse.com? It's a better list for Oracle stuff than this one... --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-unsubscribe@opensuse.org For additional commands, e-mail: opensuse-help@opensuse.org

OK, it is now running on SLES9 with Oracle 10G. I also sent an e-mail to suse-oracle@suse.com to subscribe. Thank you for the tip. I can see two AIO running when I do a ps on SLES9: root 350 6 0 10:06 ? 00:00:00 [aio/0] root 351 6 0 10:06 ? 00:00:00 [aio/1] On the aix side I can see many daemons so I was expecting more aio daemons on linux. is two sufficient? are there parameters to tune? Oracle has aio set i.e. init.ora parameter DISK_ASYNC_IO is true. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-unsubscribe@opensuse.org For additional commands, e-mail: opensuse-help@opensuse.org

One aio process per processor. --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-unsubscribe@opensuse.org For additional commands, e-mail: opensuse-help@opensuse.org
