- ORDS (oracle Rest Data services)

- ORDS (oracle Rest Data services)

Oracle now support data services - running on standalone machines, means no need of weblogic , glassfish application/ tools,

installation / is simple need to define
Port and Image in

standalone.http.port=8080
standalone.static.images=/home/oracle/apex/images

Based on the installation in the linked article, you will find the standalone settings in the following file.

/home/oracle/ords-3.0.7-conf/ords/standalone/standalone.properties

-------------

you can always star the service using

cd ~/ords-3.0.7
$JAVA_HOME/bin/java -jar ords.war

ctrl+C will stop the service, for production environment , use Nohup to run the process in backgrond and you can kill the process when you want to stop.
