Is there any way to check on the progress of an index rebuild? (Oracle 8i). I.e., it 
would be nice to get some indicator as to how far an index rebuild has gone, something 
like "75% done...".

As a rough indicator, I've noticed when rebuilding/moving an index to a different 
tablespace, Oracle will allocate temporary extents in the tablespace to which the 
index is being moved. 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). 

Are there better ways to see the progress of an index rebuild?

Thanks for any help.
