How to “user defined functions (UDFs)” without the Streaming Cockpit

Hello,

on our HANA SP9 SDS development system I currently cannot not use the SAP Streaming Cockpit (btw.  My issue with the streaming cockpit is
discussed at SAP Support message and will be fixed in HANA SP10)

So currently I cannot apply the “Enabling External User-Defined Functions” in the Streaming Cockpit as
described at

http://help.sap.com/saphelp_esp_51sp09_cp/helpdata/en/8d/b8047e09364c159c13726f2d2a3e3f/content.htm”

I assume that I can change this cluster setting in the cluster_config.xml I retrieve with

$STREAMING_HOME/bin/hdbstreamingserver -u –config cluster.cfg –show > current_config.xml

set “udf = true” parameter  and deploy

$STREAMING_HOME/bin/hdbstreamingserver -u –config cluster.cfg –deploy –config-type file –file current_config.xml

But I don’t know the correct syntax of this   “udf = true” setting in the cluster.xml and don’t like to try and error.

Can someone help me with this?

best

Roger
