Looking to replace our existing message switch with Broker on Z/OS.
We have a number of protocols between apps and the current message switch (i.e. Lu6.2 over IP).
The blurb surrounding version 6 mentions protocol conversion and IP support but cant find any details on it? Will we have to code our own session level handling (i.e. resync) in Java nodes for these app protocols in the Broker or does it come with some clever session/application level protocol handlers (window size etc etc).?
Any ideas or anybody had experience in doing this? |

are you looking for the broker to wrap/unwrap your LU6.2 traffic from the TCP/IP envelope? The broker can't do that ...

| Guess easiest way to explain is need functionality for other protocols similar to what MCA does in MQ, so initiate link between app and middleware, window size and depth, resync in case of failure etc etc all MLP type items. otherwise what does IBM mean when they say: 'V6 implements protocol conversion"? |

More along the lines of hhtp(s) <-> mq <-> jms (realtime) <-> scada <-> mqE .....

Got you, well thats good for the new stuff but we've even got some X25 still floating about.. let alone inhouse developed protocols and telex... and LU6.2 being IBM..... so much for legacy app inclusion 
Was hoping the FN pack might help, but sounds like might have to dust off java skills and write from scratch, cheers for the info. |

MQ itself will bridge LU6.2 to TCP/IP... Just create an LU6.2 Receiver channel and a TCP/IP Sender channel... And cause messages to move through both.
But both ends need to be already using MQ.
I suppose you could modify the TCP/IP Nodes that are in a support pack IA98 to speak LU6.2 and your other protocols.
Also I know there is a WBI Adapter for TCP/IP, there may be for other protocols. If there isn't, you could probably pay the Dublin lab to write one for you.

| Thanks for that info, also looking at session / application level issues. |

| Impacting the clients is not an option sadly, cant put a new middleware product in and tell all the legacy apps to change in the real world! Costs too much. |
