Hi,

I am trying to connect Raspberry pi and SDS (Hana Developer edition) running in Azure cloud. I am following the instruction given in the SAP document "

Streaming Lite
Freezer Monitoring Lite Tutorial
Document version 1.0
November
2015
SAP HANA
Smart Data Streaming
SP10

Configured all the except establishing the connection to SDS(esps://:hana.infomericainc.com:30026) server from Raspberry pi.

The error saying "Connection could be established"

We could not ping the SDS server using putty also.

Any suggestion would be very helpful.

Thanks,

Regards,

Deva

Hi Deva,

One obvious issue is with the port # that you specified. As per the documentation ( http://help.sap.com/saphelp_hana_options_sds_adapt/helpdata/en/0c/2bfd028a8e42b482e3cdf396aa0bdb/content.htm?frameset=/en/0c/2bfd028a8e42b482e3cdf396aa0bdb/frameset.htm¤t_toc=/en/5e/9157734b6548cb912d6b68f9cba830/plain.htm&node_id=321&show_children=true#jump321 ) "The Streaming Web Output adapter must be used with the Streaming Web Service." That sentence could perhaps be worded better to more clearly state that "The Streaming Web Output adapter is intended to connect to the Streaming Web Service." The corollary is that the SW Output adapter does not connect directly to the SDS server but rather has to connect through the SWS.

By default, the SWS listens on port 9093. You will notice that this is (of necessity) a different port than the SDS server itself uses. The SWS in turn would connect to the SDS server over port 3XX26. You can confirm your SWS configuration through HANA Cockpit, but unless you have changed the port from the default then the SWS will be listening on port 9093.

If you haven't already configured the SWS to start automatically, then you will need to do that as well.

On a side note the SW Output Adapter docs also state that the adapter uses port 8000 be default for the SWS connection. I'm following up on that as it doesn't make a lot of sense for the SW Output adapter to default to a different port for the SWS connection than the SWS itself uses by default.

Thanks

Rob

Thanks Rob.

I will follow the steps and try connecting the SDS thru SWS.
