Just a comment....I just noticed that for bigfile tablespaces, ASSM is
required.....hmm....I guess that answers the question of ASSM vs. MSSM.
I'm setting up my test environement w/ 10gR2, three node Opteron RAC
running 64-bit RHEL4, w/ ASM. With ASM, it makes a lot of sense to have
one datafile per tablespace, that autoextends, and use bigfiles. That
way, you never have to add a datafile. You just monitor the free space
in the disk group, and add space at the diskgroup level, when necessary.
But, bigfiles require ASSM....though I'm not sure why...it doesn't
strike me that those two features would be related....but apparently,
they are.
