System and method for accessing mainframe system automation from a process automation application
A system and computer-implemented method communicatively interfaces a Process Automation (PA) application executing on a mainframe computer with a mainframe automation function executing on the mainframe computer. The PA application executes within a services layer, which runs on top of a base Operating System (OS) layer of the mainframe computer. Some automation functions execute within the base OS layer, while other automation functions within the services layer. Therefore, an interface executing within the services layer determines which of the two disparate execution environments is needed to execute a given mainframe automation function, and invokes the function within the appropriate environment.
