How to put response in different Queues in MQ Virtualization

  • 1.  How to put response in different Queues in MQ Virtualization

    Posted 08-30-2018 07:00 AM

    Once DevTest listens request from REQUEST_QUEUE, It needs to send 2 responses one after other in 2 different queues.

     

    Scenario:

    Request Queue Name: ENV.SIT1.REQUEST

    Response Queue 1: ENV.SIT1.PAY.RESPONSE

    Response Queue 2: ENV.SIT1.AD.RESPONSE

     

    I need to send 1 response to ENV.SIT1.PAY.RESPONSE and other response to ENV.SIT1.AD.RESPONSE. How we can do this in DevTest when I have create MQ Virtual Service through request response pairs?

    There are multiple ways to do this: 

    Option A:  (Preferred)
    With the new 'IBM MQ Native' protocol, you can put multiple response queues into a single Respond step.
     1. Create a separate queue asset for each of your response queues. 
    User-added image

     2. Add multiple response channels in your VSM 'Respond' step (or in the VSE recorder when generating your VSM).  Create a separate channel for each response queue and give it a name.

    User-added image
     3. In your VSI service image, find the 'channel.name' property in the response meta-data of each transaction and change its value to match the name of the response channel corresponding to the correct response queue.

    Option B:

    You can do this with a response-side scripted DPH :
    if ("A0001JH3".equals(lisa_vse_request.getMetaData().getParameterValue("...field.Usario"))) {
        lisa_vse_response.getMetaData().setParameterValue("channel.name", "Response 2");

    } else {
        lisa_vse_response.getMetaData().setParameterValue("channel.name", "Response 1");
    }




    Option C:

    Add a Scripted Assertion, 

    • Change the assertion in the Image Selection Step to a Scripted Assertion and set the responseChannel property based on the input parameter.

    Set the Assertion to FAIL if False.
     
    // set the response channel 1 or 2 depending on the input arg
    // use getStateString in case the argument is not parsed by the XML dph
     
    if ( “A0001JH3”.equals( testExec.getStateString(“requestMsg_dse_formattedData_kColl_field_1_value”, “unknown”) ) {
          testExec.setStateValue(“responseChannel”, “Response 1”);
    } else {
          testExec.setStateValue(“responseChannel”, “Response 2”);

    Hi Shiney.

    The images you uploaded, i guess they are not visible. Could you please upload it again, so that I can have clear idea about it.

    Hi Shiney,

     

    I did exactly the same way you recommended in option 1. But the third response I am not able to put the 3rd response in ENV.SIT1.AD.RESPONSE .

    MQ team says, all three responses are getting dropped on Single Queue (ENV.SIT1.PAY.RESPONSE).

     

    Response Queue 1: ENV.SIT1.PAY.RESPONSE

    Response Queue 2: ENV.SIT1.AD.RESPONSE

    Pranay,  can you share your VSM/SI ? I can take a look at it. 

     

    You can also open a ticket with CA Support and I can assist you in a webex. 

     

    Thanks

    Hi Shiney,

     

    I have made some changes as original project I cannot share. Please find the attached LISA project for the below Details:

    Req Queue Name: DEMO_REQ_QUEUE; LISA Channel Name Given: CARS.REQUEST

    Rsp Queue Name: DEMO_RSP_QUEUE (Response 1 and 2 drops in this Queue); LISA Channel Name Given: CARS.RESPONSE

    Another Rsp Queue Name: DEMO_ACK_QUEUE (Response 3 drops in this Queue; LISA Channel Name Given: CARS.ACK

     

    Other details are in assets. I will try to raise ticket to have webex with you.

    Hi Shiney, I am unable to upload the project from my machine. Probably restrictions. Is it possible if I can share you webex link through mail and you can guide me?

    Hi Shiney,

     

    I am able to put the response in two different queues now. But I was able to do this with old IBM MQ WebSeries Deprecated protocol. Things I changed here were:

    • As suggested by you: changed the dest.channel  and dest.destination in VSI.
    • But it still did not worked till I changed the disregardReplyTo = true. And then the 3rd response dropped correctly in second Queue.

     

    What should i change in new IBM MQ Protocol to have same effect. I do not find disregardReplyTo in IBM MQ Native protocol. Please help.

    Please verify your VSM 'Respond' step   Response 1, 2, 3  and VSI service image, ( 'channel.name' ) Response 1 , 2 and 3  matches.  

     

    Thanks

    Shiney.

    Please find the screenshot:

    1) Respond step - Channel Names

     

    2) VSI channel.name - Assume response 2 to drop in RESPONSE.PAYMENTS and response 3 in ADVICE.PAYMENTS

    Hi Shiney,

     

    Any idea what to change in VS created by IBM MQ Native. I have attached screen shot and have used correct name in VSI and VSM with respect to channel name. abrsh01

    Able to resolve the issue with IBM Native MQ protocol abrsh01. By ignoring default response queue, the response message drops in specified queue.
