Home -> Community -> Mailing Lists -> Oracle-L -> Re: Move table online and update the indexes at the same time.
Tanel,
Thanks for the reply.
It's 9i. I thought about table redefinition but I am not sure how it
affect the performance. Second, I wonder if there a need to get a lock on
the table just for a split of a second. We do not have any chance locking
the table since there are always several transactions using it.
What is your experience? Since it appeared only in 9i I am a bit worried
about using it.
Thanks,
Alex

Oracle 10g: alter table shrink space cascade
Oracle 9i: dbms_redefinition package
Pre-Oracle 9i: custom mechanism, cloning table and recording changes with
triggers or snapshot logs.
