Hi Dimitre,
I am using direct path insert, which writes above the HWM. I cannot
preallocate space in the table for that.
Regards,
L.

If you preallocate the storage, you'll avoid the updates on tsq$.
Try insert/truncate reuse storage and reinsert, the waits have to
disappear.
So if you know the regular size of the tables, you could prepare the
storage.
