An open query(no insert, no update, no delete) is enough to stop the
OAT from advancing, since it uses a transaction as well. And, if you
use the same transaction to insert, update and/or delete, then you can
see why the OAT might not be advancing.

OAT problems can be produced with other connection solutions(other
than IBO), if the transactions are not handled properly(i.e.
transactions that are active for a long time).
