Hey @Dileep_V_S! The mechanisms are the same like here: List of available override the application properties (like database settings) in EHRBase - #5 by jake.smolka
So you could change the node name with, for instance:
SERVER_NODENAME=test java -jar application-0.16.5.jar
And, just as a side note, to quickly check the result:
curl --header "PREFER: return=representation" \
--request POST \
http://localhost:8080/ehrbase/rest/openehr/v1/ehr | jq
