Kevin - Since you haven't received any replies, here goes. Within an extent, Oracle uses blocks. I haven't seen a way to find the used space within a block. There are methods to find the number of empty blocks underneath the high water mark. Analyze does that, but you've ruled that out. It might help if you could explain what you are trying to accomplish. Other ideas are:

Hey guys;
  Does anyone know where I can look to find the space remaining in an individual extent ?? I know that you can get the freespace from dba_free_space but that seems to be based only on unallocated extents. I have been asked to find out, down to the byte, how much free space is available ..... on the fly (which means not only after every analyze)

Any suggestions ??? I am sure Oracle has a table with the information somewhere .

Thanks

Kevin
