How to get the status of orders in quickfix

Question

I'm working with quickfixgo 5.0. in the FromApp function I'm receiving the execution report message and parsing it and trying to store it in the db. but what happens if my db connection fails and it returns error? I need to get the execution message again. but the message sender doesn't support msgType=H(OrderStatusRequest). how can I make sure that the system can have the latest order statuses?

func (e FixApp) FromApp(msg *quickfix.Message, sessionID quickfix.SessionID) (reject quickfix.MessageRejectError) {
    messageDTO := model.MessageDTO{Message: msg}
    executionReport, err := messageDTO.ToExecutionReport()
    if err != nil {
        return err
    }

    e.PersistExecutionError(executionReport)
    return
}

there is also a ResendRequest msgType. and it gets from seqNumber and to segNumber. but what if my system restarted and I needed to logon again and reset the seqNumber?
