4.6 System Tool Interface

 

The lowest level of abstraction in the tool control layer of the VISTA/SFC environment is represented by the System Tool Interface (STI) , that provides access to system executables in a uniform way. The purpose of this interface is to hide details of tool invocation that are related to queuing systems, file location of executables, authorized hosts for a given executable, and site-specific invocation procedures; basic logging and work-in-progress facilities are also offered. In this way, external tools can be accessed by symbolic names throughout all source code files and user-defined task-level applications. The actual mapping from the symbolic name to the operating system's command line is defined in a central configuration filegif.
