HANA Express: Streaming server tutorial / Name resolution

Dear experts,

I was running through the steps of the tutorial and noticed an issue when starting the service from Eclipse. It errored out showing:

Failed call to:https://gunter-hxe:49901/RPC2 (Failed to read server's response: gunter-hxe)
Failed call to:https://gunter-hxe:49901/RPC2 (Failed to read server's response: gunter-hxe)
Failed call to:https://gunter-hxe:49901/RPC2 (Failed to read server's response: gunter-hxe)

Now with wireshark I figured out it's a DNS issue because the fully qualified domain name (FQN) is cut by Eclipse. Unless I missed something I'd say that's a bug somewhere in the streaming plugin for eclipse (request goes from Eclipse to HANA Server).

It's cutting away the domain. Could someone look into that? I added the "gunter-hxe" to the hosts file on Windows and it works. but it should be the FQN which is gunter-hxe.<domain name>. Of course the correct name is set in Eclipse everywhere.

When installing Streaming, one of the first questions that the installer asks for is the hostname. That hostname needs to be fully qualified. It seems that it’s that hostname that’s used for the RPC calls. So I’d guess that when streaming was added, you chose “gunter-hxe” instead of “gunter-hxe.something.something.else.sap.com” as the host. I don't know of a way to change it other than to uninstall and re-install Streaming.

Hi Jeff,

thanks for the answer, that seems to be the root cause. Thanks for making that clear.

Hi

So your thread, Im also struggeling installing streaming server. Is is so that when you run install_hsa.sh and you are asked for host name, FQDN is needed?

FQDN is preferred but not always possible, in part due to network configuration. When using the VM install, then the VM is already assigned a host name of "hxehost". When not using a FQDN, you then need to edit the /etc/hosts files on the server and the client sides to alias the unqualified domain name to the IP address.
