Hi, Yes, changing the metadata.xml file won’t work as it is not read at runtime. What you can do is to externalized the instance declaration in a ‘cfg’ file (if your runtime support this format). cfg files are generally use to push configurations to the configuration admin.
In your case it would be something like : tcp-handler-instance.cfg, with the following content: serverIP=…… serverPort=8080 Changing the cfg file reconfigure the instance.

However, it seems to me you need to find a better way to configure this kind of thing... Maybe others can help here?
