While that would be nice, I would submit that if using ASM, usage becomes
solely a DBA problem. From the OS level, as a system admin, I don't really
care…I refer any questions back to the DBA. They should have tools to deal
with all that.
OTOH, with more things stacked on more servers (zones, etc.) I might care if
there's a chance of whatever Oracle is doing affecting performance elsewhere.
Thoughts?
