There is not a HWM indicator for an index as there is for a table. When a truncate occurs, the blocks are cleared in the index and the extents (beyond the initial extent) are deallocated (assuming you do not issue the reuse storage clause).
RF -----Original Message----- Sent: Tuesday, April 09, 2002 5:52 PM To: Multiple recipients of list ORACLE-L Hello, Lisa, what I was wondering when I read Rick's e-mail was... what about the HWM for the indexes when someone truncates a table. The table's HWM pointer gets reset of course, but I can never recall seeing anything about what happens to the index space.

Try it. You'll see that the extents clear up just like the extents in the table do, if you don't specify the REUSE STORAGE clause.
