Hi All,
I have an asincronous application that act as gateway from VAX to JAVA applications.
This Infrastructure is based on WebsphereMQ Webshphere6.0 and VAX+WebspherMQ on the host part.
Messages on the Queue are read by an MDB that executes operations.
VAX ---------->WSMQ queue 1---------------->WS JMS(MDB1)
By this architecture application is difficult to scale, if adds queue, it's necessary to redeploy the
application with 2 or more MDB.
VAX ---------->WSMQ queue 1---------------->WS JMS(MDB1)
VAX ---------->WSMQ queue 2---------------->WS JMS(MDB2)
VAX ---------->WSMQ queue N---------------->WS JMS(MDBN)
There is some possible work on java architecture to increase scalability?
Best Regards
Xavier |

| I quite didn't understand what you are saying, but you can configure multiple MDBs to one MQ Queue. |

Usually, the data in different queues is different and requires different logic to process.
So usually there is a good reason to have more than one MDB for different queues.

I would be interested to know how you send data from a VAX system to MQ. As far as I am aware there are no supported MQ options for VAX hardware.

More than one JMS Destination can easily point to the same MQ Queue.

At the same time remember that you can have more than one instance of the same MDB running on one queue. You just need to plug in the number of instances in the config of the MDB.
Enjoy

Would this work If we consider Synchronous Messaging???[/code][/quote] |

MQ Series is by essence ASYNCHRONOUS. So I have no idea what you are talking about with Synchronous messaging...
However the request response design pattern may make it seem quasi synchronous...
Enjoy

a bit perplexed as to all the talk about creating multiple MDB's to listen to a particular queue.
why not use connection pooling which essentially allows you have concurrent processing of all messages with a single MDB implementation??
I am talking about WMQ ans WAS obviously.. |

Because, perhaps, you have decided to inappropriately share a queue between different logical functions.
