IBM MQ settings

Defining the IBM MQ request and response protocol

In FTM service participant and channel definitions, the communication to and from the connector use the IBM MQ request response protocol. This protocol is defined as the default setting in the TCH reference application. For the connector, it is important to define Tco_FTMReplyToQueue for each connector instance so that the responses to requests from RTP are sent back to the same instance of RTP.

Message expiry

In immediate payment processing, messages are not worth being exchanged after a certain amount of time. Protocols that are defined by the payment schemes support the correct behavior, even when messages are lost because of technical failures or slow network performance.

The FTM TCH connector component uses message expiration settings according to TCH specifications. The message expiration for echo messages, payment messages, and non-payment messages is set by using the TCo_RTPMQExpiry property. The default value for this property is 10, which matches the TCH specifications.

SNM messages that are received from TCH are persistent and do not expire.
