    - You can force the failure of a distributed transaction for the following reasons:

    1. To observe RECO automatically resolving the local portion of the transaction

    2. To practice manually resolving in-doubt distributed transactions and observing the results

    - RECO (Oracle RECOverer Process) is an Oracle background process created when you start an instance with DISTRIBUTED_TRANSACTIONS= in the initialization parameter file.

    - The RECO process will try to resolve in-doubt transactions across Oracle distributed databases.
