    Please let us know if Virtual Service Tracker step has both Image Response and Live Response fields set or not. 

     

    Thanks,

    Surya.

    Can you please confirm that the properties are set in the section as shown below.

    Yes I can confirm these only properties are set. Also have noticed here I have modified VSM with two Response Selection. And from first Publish Selection, I have removed VSE Message Workflow assertion. I have removed that because I want to achieve one scenario here(i.e. for one request , sending two responses to two different queues)

    Hi,

        Make sure virtual service execution mode is either "Image validation mode" or "Live invocation mode" and add an assertion like below and route request to Virtual Service Tracker step as shown below to execute this " Virtual Service Tracker step" only during  "Image validation mode" or "Live invocation mode".

     

       

     

    Thanks & Regards

    Hello Srikanth,

     

    Please find screen shot of my VSM. and suggest me the reason and what changes I can do here.

    I notice two VSI Selection steps in the model posted above which makes this a custom VSM, IMO. I wonder if there are issues related to attempting to transaction track using two VSIs. I am not clear on what events are raised & reported in the database in this situation.

     

    sursu06 do you know what happens if trying to track against 2 VSIs? I am curious if the second VSI's tracking events are throwing the exception.

     

    I would assume the same incoming request is used in both VSI Selection Step responses. Is there any possibility of adding two (i.e., multiple) responses into a single VSI and publishing each response to the respective queue? 

     

    As an aside, when one customizes a VSM by adding steps, it is possible to break or disable some of the learning, tracking, live mode logic.

    Hello Joel,

     

    There is way to configure two responses in single VSI and send them to diff diff queues. But that is not working unfortunately here. Even Kevin/David Woodman also checked not able to work. So David suggested this way.

     

    In 7.5.2 , I am getting this exception, but in 10.1 version , VSM is totally different. So with help of David, I implemented this in latest version and it is working there.

     

    So this was whole and brief picture behind this. hope it is bit clear to you now.

     

    But I am curious to know , even David checked this exception not able to found root cause, why this is happening? any way we can resolve this exception?

     

    Please advise. If we gonna resolve this exception then we can achieve this in 7.5.2 version as well.

     

    Cheers..

    Firstly, continue following the direction provided by Kevin & David.

    In terms of 7.5.2, it would be best if you can upgrade. Support is no longer available. 

    In terms of the exception, I do not know as I have not seen this exception. I was curious a model having two VSIs could be creating a strange scenario that could cause the issue; hence, my shout out to Surya to see if he had seen this.
