A Job Server processes scheduled actions on objects at the request of the CMS. You can configure a Job Server to process either report objects or program objects when you add it to your Crystal Enterprise system. If you configure a Job Server to process program objects, it becomes a Program Job Server.
Program objects allow you to write, publish, and schedule custom applications, including scripts or Java programs that run against, and perform maintenance work on, Crystal Enterprise.
The Program Job Server processes scheduled program objects, as requested by the CMS. To run a program, the Program Job Server first retrieves the files from storage on the Input File Repository Server, and then runs the program. By definition, program objects are custom applications. Therefore the outcome of running a program will be dependent upon the particular program object that is run.
Unlike report instances, which can be viewed in their completed format, program instances exist as records in the object history. Crystal Enterprise stores the program's standard out and standard error in a text output file. This file appears when you click a program instance in the object History.
