Activate – activates a subscription. This menu item is active only when you have indicated you are using bulk materialization to materialize the database.
Validate – validates a subscription. This menu item is active only when you have indicated you are using bulk materialization to materialize the database.
Delete – removes the database subscription from the environment.
Properties – opens the Database Subscription Properties dialog box, which is similar to the properties dialog box for database replication definitions.
