Resolution: In Integration Manager, RVCM advisories go to the Engine console. However, if you want to capture the advisories, you will have to do it within IM. You will have to create an IM Subscriber listening to these advisories, which uses the same transport as the publisher. An RVCM example that is shipped with the product, demonstrates this. You can have a look at the example features_channels_rvcm_publish.dat
