Dial-up problems

 

WebSphere MQ supports connection over dial-up lines but you should be aware that with TCP, some protocol providers assign a new IP address each time you dial in. This can cause channel synchronization problems because the channel cannot recognize the new IP addresses and so cannot ensure the authenticity of the partner. If you encounter this problem, we need to use a security exit program to override the connection name for the session.

This problem does not occur when a WebSphere MQ for iSeries, UNIX systems, or Windows systems product is communicating with another product at the same level, because the queue manager name is used for synchronization instead of the IP address.
