Kirti,

In LMT you can query the X$KTFBUE which is roughly equivalent to UET$ in DMTs.

select v.name "FILE NAME",count(x.KTFBUEFNO) "TOTAL # of EXTENTS" from V$datafile v, X$KTFBUE x
where v.file#=X.ktfbuefno
group by v.name;

Ethan, Is this what you are looking for or something else?

Best Regards,

That's what I thought too, but it will skip extents from any LMTs in use. And getting extents info when LMTs are is use will be slower as compared to DMTs due the way this info is stored in the bitmap in each datafile for the LMT.

How about counting rows from uet$? I have not tried it.

                    Please

                    respond to

                    ORACLE-L

Anyone recommend a faster access path for getting the total number of extents in the database? select sum(extents) from dba_segments is too slow for my purposes.
