Public Interfaces Overview In the Foundation1 development environment there are several public interfaces to components which make life easier when developing business applications. In the Business Logic layer these interfaces consist of public methods in system services and public logical units. In the client framework the interfaces are made up from public messages and methods. The methods can be either internal functions or member functions of classes and service objects. These public interfaces described below, are the only interfaces supported between different releases of Foundation1, hence the descriptions below do not include obsolete interfaces. System Services Batch_SYS This package provides services related to batch processing. To be able to use this package, the DBMS_JOB service in the Oracle environment must be installed and some processes must be initialized through INIT.ORA parameters. Exist_Batch_Schedule Exist_Batch_Schedule (schedule_name_) RETURN NUMBER Schedule_name_ IN VARCHAR2 Name of the batch schedule Purpose This function checks whether a scheduled background job with the specific name exists and returns the number of such scheduled background jobs. Parameter Description Schedule_name_ The unique name of a scheduled background job. Returns The function returns the number of scheduled background jobs with this unique name. Pragma None Comments Example IF (Batch_SYS.Exist_Batch_Schedule(‘ANALYZE_SCHEMA’)0) THEN -- At least one batch schedule with this name exists! ELSE -- No batch schedules with this name exists! END IF; Exist_Job Exist_Job (job_id_) RETURN BOOLEAN job_id_ IN NUMBER identity of a batch job Purpose This function checks whether a batch job exist or not in the current Foundation1 instance (application owner). Parameter Description job_id_ The identity (number) of the batch job. Returns The function returns the boolean value whether the batch job exist or not. Pragma WNDS, WNPS Comments The function ch
