Hi Diego,
If lock type is 'TX', rollback segment number = trunc(p2/65536)
and slot number = p2 - 65536*trunc(p2/65536).
May I know which table you are looking at to get the following
detailed info about enqueue waits?

Hi Diego,

(normally a rollback segment) then a reuse block range cross instance call is
needed to flush the unwanted blocks from cache. Similarly, before a parallel
direct read a checkpoint block range or checkpoint
