What are all the pros & cons you guys can think of for allowing a external company to connect to your queue mgr as an MQClient versus requiring them to use their own internal queue mgr and configuring a SDR/RCVR channel pair ?
I know the there are more security concerns with the MQClient approach, but not sure if I know them ALL. Some can be addressed with BockIP and security exits.
I know there may be differences in the efficiency of your network bandwidth utilization, depending on how many MQClient connections are needed.
From reading this forum, it seems like the preferred MQ interface model between two different companies is point to point message channel connections between two edge servers or MQ gateways. But, using MQclient is cheaper because fewer MQ licenses are needed. Are the negatives associated with using the MQClient model heavy enough to outweigh the cost of making all our external vendors support their own queue mgr ?? |

I have not been clear about the licensing for MQ Clients when it comes to external organizations. You should confirm with your IBM sales representative whether or not that is valid.
Client connections are generally harder to troubleshoot and harder to monitor . The security issues are generally the same.

My understanding has always been the the MQ Client code is freely available to anyone, not just existing MQ Server licence holders. You could download and install it at home if you wish, but you will always have to connect to a licenced server in order to do anything.
Any external organisation could download and install the MQ client and connect to a server. Obviously the terms and conidition of the licence would have to be upheld but other than that I don't believe there is an issue.
I am always willing to have my understanding corrected if this isn't the case.  |

I may be entirely wrong on this.
My understanding is that, although the client is freely available for everyone, servers are not necessarily licensed to accept client connections from clients outside the licensing organization.
But it's been a while since I've had any conversations on this, and the licensing may have changed.

Hmmm interesting. I can see where that would make sense, but what about Web applications that connect to an MQServer? They could (theorectically) come from anywhere.
Does it depend on the client type in that case? |
