+=== Start APEX Engine
+
+In a new terminal, start APEX with the new configuration for Websocket-Server ingress/egress:
+
+[source%nowrap,sh,numbered]
+----
+#: $APEX_HOME/bin/apexEngine.sh -c $APEX_HOME/examples/config/VPN/Ws2WsServerAvroContextJsonEvent.json
+----
+
+[source%nowrap,bat,numbered]
+----
+#: %APEX_HOME%\bin\apexEngine.bat -c %APEX_HOME%\examples\config\VPN\Ws2WsServerAvroContextJsonEvent.json
+----
+
+Wait for APEX to start, it takes a while to create all Websocket servers (about 8 seconds on a standard laptop without cached binaries).
+depending on your log messages, you will see no (some, a lot) log messages.
+If APEX starts correctly, the last few messages you should see are:
+
+[source%nowrap,sh,numbered]
