Re: Progress of an index rebuild

Hi!

Check v$session_longops view, it is meant for monitoring this kind of long-running jobs - but it can be quite inaccurate. Another way would be to check v$sort_usage during sorting phase of index recreation and then check the newly created index segments size (it'll be created as a temporary segment initially and switched to index-type afterwards).

So, in theory, I suppose I could see how big (in terms of extents) the index is before moving it and use that as a rough indicator to see how far along the rebuild is by counting the number of temporary extents allocated in the new tablespace (taking into account the extent size in the new tablespace).
