Hi Suvash,
Everything is correct except that "space will not be used for future inserts or updates". If your pctused and pctfree parameters permits the space (holes) within a block can be filled by updates and inserts. Delete operation has nothing to do with high water mark. Currently export and import is the only way to work around the problem of block defragmentation.

Hi DBA's
I have a point, which I want to know whether I am correct.
I have a table containing a million rows. If I delete the data in bulk from the table basing on a where condition. This means that High water mark is not reset and the space that was freed will still be part of the table, and will not be used for future inserts or updates. Also this creates lot of holes in the data blocks. And I understand that only export and import is the way to get away with the holes in the data blocks.
Kindly some body tell me whether I am correct.
thanks in advance
