Hello Experts,
I am working on MQ service concept. Could u please tell me what's the difference between using MQ service and the normal MQ nodes?
I could not understand how the already existing queues will be used by the other users when they are already in use??
Correct me if my understanding is wrong..
Thanks in advance |

An MQ Service needs to start with an XML contract for the (service) queue.
The operations will then be externalized as a web service through a WSDL that gets built. This all happens automatically as you step through the wizards.
Have fun

Thanks fjb_saper for your response.
But could you please elaborate somewhat as I still could not understand its prompt use??
You said "An MQ Service needs to start with an XML contract for the (service) queue".Does this mean that the input and output schema has to be the XML schema type only??
Thanks in advance |

When using MQ Service, you are defining a contract, much like a wsdl. It will have the end points(queue/s), an operation(one-way/request-response), and input and output message types(XML user defined types/built-in elements only!). You start with creating an MQ Service first and then applying it to your MQ nodes.
By doing this you have a description of the API that your message flow represents and when added in a library the MQ Service file can be re-used in other message flows, thus immediately configuring your new MQ nodes. |

Hey Thanks menonshankar for your response..
I understand that the MQ service we have defined is re-usable,what I don't understand is that the MQ nodes which have the services(queues) are already used by one of the project then how can we re-use those working services(queues) ?? I hope am being clear in my explanation...
Thanks in advance |

Hello All,
I have been trying to publish the mq service to the Integration registry but it is always in OFF state. I got to know that the Integration registry will be UP by default when the Integration node is started. But in my toolkit the registry is always in OFF state.. What could be the reason for this?? Can anyone please let me know??
Thanks in advance. |
