Establishing MQ connections for FMT FIN

When FMT FIN messages are to be sent to an LT that belongs to a different FTM SWIFT instance, the queue managers of the sending and receiving services must be connected by two MQ message channels (one for each direction). Each of these two message channels requires two channel definitions:
  • The sending system requires a sender channel definition for the sending queue manager
  • The receiving system requires a receiver channel definition for the receiving queue manager
For information about how to create message channels, see:
  • IBM MQ: Intercommunication
  • IBM MQ: System Administration Guide
  • On the receiving system, give all user IDs that are to be able to place FMT FIN messages into the queues with names of the form instance.ou.DNF_PF_IR authority to write to those queues and to the dead-letter queue (DLQ) of the receiving DNF_PF_IR service. You might also need to give these user IDs write access to additional IBM® MQ resources.
  • One way to ensure data security without having to administer the rights of users who are at remote systems is to do the following on the receiving system:
    1. Create a special user ID to be nothing more than the MCA user of the message channel. Do not give this user ID any access rights other than those required to receive FMT FIN messages.
    2. Set PUTAUT to ONLYMCA.
