I know there are many threads on this forum discussed on this. But this one is bit different. I have an application that was coded to make client connection from machine m1 to remote queue manager Q2 on machine m2. M2 has the MQ server software installed. Now it is decided to install MQ Server software on machine M1 and move the queue manager Q2 to machine m1.
My queustion is: should I change the application that used to make client connection, to make a "bindings mode/server mode" connection to connect local queue manager Q2? Will there be any advantages by doing so performance wise? |

You don't have all the facts about anveshita's app to make that kind of call.
sever binding to a local queue manager will always be more reliable and perform better than client to a local queue manager. That pretty much sells it for me.

Well if Performance is the key here then definitely yes, binding is better than client..but as jeff pointed out in my other thread, it might not matter at all. Clients do povide certain advanatgaes compared to binding. That said, its a choice of application design to go which way they want considering other aspects as well.
I have read many posts on this and do have a feeling many GM's out here do prefer to have client connections. But as qabbadely rightly pointed out it was too early to make the call from whatever info anveshita has provided. |

He especially did not specify if there had been any changes in the app that would need a 2 phase commit with the qmgr as transaction coordinator....
