Scheduling is a process which allows you to run an object automatically at specified times. When you schedule an object, you choose the recurrence pattern that you want and specify additional parameters to control exactly when and how often the object is run.
At the time you schedule an object, the system creates a scheduled instance. Although a scheduled instance appears in the History dialog of a respective object (with a status of Recurring or Pending), it contains solely object and schedule information—it does not contain any data.
When the system runs the object, it creates an output instance for the object (for example, a report or program instance). A report instance contains actual data from the database. A program instance is a text file that contains the standard output and standard error produced when the program object was run. Output instances also appear in the History dialog of an object and have a status of Success or Failed.
For end users to schedule and run objects, they must use a web-based client such as InfoView or a custom web application. InfoView is designed primarily to schedule objects and view reports, whereas the CMC enables you to manage and administer objects in addition to scheduling objects and viewing reports.
