If the file esists, you do not need to take any further action.
If the file is not present, ensure the following environment variables are set:
echo $APPSERVER_HOME
echo $VP_HOME
Ensure that each command mentioned in step 2 returns a valid path.
If the paths are valid, run the command: sed "s@%%APPSERVER_HOME%%@$APPSERVER_HOME@" $VP_HOME/Support/AppServer/appserver.service > /etc/systemd/system/appserver.service
