Specifying Selectors

Specify message selectors for global topics as properties of routes. You can define these properties in two ways:

  • Define selectors when creating the route (either in routes.conf, or with the administrator command create route).
  • Manipulate selectors on an existing route (using the addprop, setprop, or removeprop administrator commands).
Note: If you change the message selectors on a route, only incoming messages are evaluated against the new selectors. Messages pending in the server are re-evaluated only if the server is restarted.
