ASM is mature. It's been around since 10g. (note than 11gR1 has been around for almost two years now)
In 11gR2 ASM has been expanded so that data files (e.g. Oracle instance files) can also be stored on ASM rather than on the filesystem. People just don't like using ASM because they like to "see" those data files sitting on their OS filesystem. Easier to backup, they say. It's also less efficient and less performant. And not auto-tunable. ASM + Oracle DB can do automatic load-balancing of data across available spindles. Takes a lot of the administration out of the DBA role, plus when you put in ADDM, Diagnostics & Tuning... pwede nang pumetiks! :-) On Tue, Apr 21, 2009 at 1:28 PM, Cocoy Dayao <[email protected]> wrote: > > On 04 21, 09, at 12:58 PM, Orlando Andico wrote: > >> BtrFS is from Oracle, but the "religion" is that screw the FS, use ASM >> and raw devices. >> >> > > that one i didn't know. been waiting to hear when the tech's all > mature to try it out. -- Orlando Andico +63.2.976.8659 | +63.920.903.0335 _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
