Setting a value of false for the user.allow.link.based.workareas key indicates that you want to start Rational Synergy in copy-based mode. This causes work areas to be copy based by default. Type the setting in the following form in your $HOME/.ccm.user.properties file:
user.allow.link.based.workareas=false
Setting this value to anything other than false will cause Rational Synergy to start in link-based mode. Note that the value is case-insensitive.
