MessageYou still can have row migration when pctfree is set too low. ASSM doesn't resolve that. But yeah, ASSM removes the pctused and freelist/group issues (and introduces others :)

And why not? Forgetting about PCTFREE/PCTUSED is the main point of automatic segment space management. Initial/next are resolved by using LMT, because that's what takes care of your extent sizes.

Hi Mladen,

I can't help you with your problem, I haven't had the pleasure on NT or Tru64 but I just wanted to point out that you can't forget about PCTFREE even with ASSM.

Cheers

Richard

I have RDBMS 9.2.0.4 on RH 7.3 and I executed the following command:

create tablespace wizard
datafile '/oradata/WIZ/wizard01.dbf' size 3072M reuse
autoextend on next 1024M maxsize 16385m
extent management local autoallocate
segment space management auto;

The whole system just hung, doing I/O like crazy. I was unable to killl one of the server processes
which survived even shutdown abort, so I had to bounce thw whole box. No errors, no traces, no
anything. Does anybody else have experience with this? Is there a known bug (not currently known
to me) with a patch that I can install? I'd really like to use "SEGMENT SPACE MANAGEMENT AUTO"
and forget about pctfree/pctused stuff.
