Response Mode

The Event Settings section includes one attribute, Response Type, for setting the object's Response mode. If Without Response is selected for this attribute, the attribute Maximum Retrieval Hours is available for setting the rejected message retrieval filter.

The following response modes can be selected:

With Response

Select this mode to receive notifications about the delivery status of messages for the OCO calls. If you select this mode, you will receive notifications, such as messages are successfully delivered or messages are not delivered due to system or communication errors.

Without Response

Select this mode if you do not want to receive the notifications about the delivery status of messages for the OCO calls. The messages that are rejected by the MES middleware are stored in the Rejected Messages table in the MES database.

If Without Response is selected as the response type, the Maximum Retrieval Hours box becomes available. Rejected messages that occurred up to the number of previous hours entered here will be retrieved. The range of values is 1 to 100. The default is 72. Every hour, the object will set the Time filter to a value in the past that is the number of hours entered in this box from the current time.

The middleware can reject messages due to system or communication errors or other errors such as invalid inputs.

To allow an OCO to log messages in the Message Queue while in Without Response mode, an Anonymous Logon user with the Send Message privilege must be added to the MESAsyncQueue on the middleware server. Otherwise, the messages will not be logged. See Add an anonymous logon user to MESAsyncQueue.

You can view, edit, and resubmit rejected messages using the Rejected Message Viewer feature in the MES Client application. For information about using the Rejected Message Viewer feature, see the MES Client User Guide or online help.
