Use the CHECKPT function to add or delete a record in the BSDS checkpoint

and CANCEL keywords to delete a record.
This can override WebSphere MQ efforts
to maintain data in a consistent state. Only use this function when implementing
the disaster recovery process described in
Recovering a single queue manager at an alternative site and
Recovering a queue-sharing group at the alternative site, or under the guidance of IBM
(R) service.
