Thanks darren.
A few further Q on your points
Regarding aio. On filesystem, I know on solaris it uses threaded model(lwp) to
simulate asyhch io. Not sure what is oracle aio on Linux now ,anyone has
details/internal implement ions..? On filesystemio-options, not sure how
efficient it is comapred to Asm native aio/dio.
Regarding multipathing, solaris has it's mpio(did I spell it right.), did Linux
now has something similar (udev u guys talking about?) how mature it is?
The answer I want to ask the list friends is:
For those who are running oracle on Linux, how many of using ASM and how many
uses ext3/vxfs?
How many using VCS and how many using CRS?
Thx
Best regards
Zhuchao
