Enable and configure Guaranteed Delivery for a project, submodule, or stream in the Properties view of Sybase CEP Studio with setting options.
Use properties of the CREATE MODULE and CREATE STREAM statements to enable Guaranteed Delivery on a module (in the Sybase CEP Eclipse plugin only) or stream. For more information about the Properties pane, see the "Editing Query Module Properties" section of the Sybase CEP Studio Guide . For more information about the CREATE MODULE statement, see the Sybase CEP Eclipse plugin documentation. For more information about the CREATE STREAM statement, see the section of the same name in the Sybase CEP CCL Reference Guide .
Sybase CEP query execution is repeatable. Providing the same inputs to multiple executions of the same query will produce the same result. This characteristic allows Sybase CEP Engine to recover from a failure, since it can, in essence, pick up where it left off. Note that there are a few CCL exceptions to repeatability, such as the RANDOM() and NOW() functions, which are designed to return a different result each time you call them.
