I had made a mistake of specifying my SDS port as 30016 earlier but later changed it to 30026 as advised. Now my streaming projects seem to be working correctly via the SYSTEM ID.
But when I move over to the HANA Admin "Landscape" tab, I can see that my streaming server has been configured on 30016! ( As shown in the image below)
I am a little confused how my streaming projects connect to 30026 port and run automagically. Am I missing something here?
