INDEX REBUILD. EXTRA SPACE REQUIRED

edited May 13, 2009 5:00AM in Database Administration (MOSC) 5 commentsAnswered
Hi, I have tested to rebuild many partitioned indexes since i plan to move the related partition with this sentence:

alter index owner.idx_name rebuild partition part_name tablespace ts_name parallel;

Too much space was allocated (and wasted). 

Many notes indicate that no extra space is required when an offline rebuild is done, but as you can see I didn't use online option and extra space was used anyway (by the way offline is the default option, isn't it?).

Can you help me with this issue?

What is the rebuild option that doesn't require a lot of extra space?

Howdy, Stranger!
