I had the same problem when truncating a huge table (24 Mill rows). It
turned out that the reason my table was taking so long was the amount of
extents I had on it. I could look at what was actually happening during a
truncate and it had to go and take each individual block and put them back
in the available lists.
Well, after changing the settings on the table to make larger extents (and
therefore fewer) the truncates on that table went hundreds of times faster
(we had real bad settings on that table before).
You might investigate your storage parms and see just how many extents you
do have on that table.

Hi All,
Is there any way to speed up the truncating a big table with 12 million
rows?
Basically, I implemented truncating that big table on Production, but it
affected the performance much, so I had to stop it in the middle of way. All
the rows were truncated but the HWM was not shrunk at all. I want to do it
again to get the space back. Is there any way to speed up this process?
Platform: Oracle EE8.0.6 and Solaris 2.7
Thanks a lot in advance.
Chuan
