Error description

  • If the first MQ operation in syncpoint fails, the MQ
    transaction may continue to have problems.  This can result in
    uncommitted messages increasing on queue(s), and then problems
    at commit or rollback time where the messages are not committed
    nor rolledback, and no error signaled to the IBM i commit
    processing.
