Ruth,
I think you'll find that with v2r3 and above the writes are done at the block level - i.e. when updating blocks using sql, the updated
data block is only written out once. I believe there will still be a TJ entry for each data row which is affected and I don't know if the
writes during rollback are once for each row or once for each block.
Most of this information is available in the release notices for v2r3 and above.
Cheers,
Dave
