reorg forwarded_rows uses allocation page hints to find forwarded rows. Because it does not have to search an entire table, this command executes quickly, but it may miss some forwarded rows. After running reorg forwarded_rows, you can evaluate its effectiveness by using optdiag and checking “Forwarded row count.” If “Forwarded row count” is high, you can then run reorg compact, which goes through a table page by page and undoes all row forwarding.
